Flash tuning 101: ECU Re-mapping By Dan Everett, 15 Apr. With most modern common-rail turbo-diesel engines you can expect a 20-30 per cent increase in power and torque with just a tune. Other times they’ll have tiny issues that you need to chase and do the tune specifically for the car. I’ve been working on a Hilux at the moment for. Just Autos can remap your vehicle to your needs; towing, performance, economy – you name it and we will custom tune it on our in house Dyno Dynamics dynamometer. With a Just Autos custom remap, EGR (exhaust gas recirculation) functions can be switched off in the ECU, this stops abrasive diesel exhaust gas being recirculated through your motor.

Intro Guide to Do-It-Yourself ECU Map Chip Tuning / Programming / Flashing (Using HEX Editor)

PART 1 of this article will talk about basics of ECU. You'll first need to get familiar with this information before attempting to code (as discussed in PART 2).

PART 2 demonstrates example how to program ECU via HEX coding software.

First a basic beginners guide introduction into world of car tuning and what you need to know:

The ECU of your car is like its brain. For your car to deliver it’s best performance you have to keep it in a fit condition at all times.

This is the only way to ensure that you get the best in both driving as well as handling. Modern day cars do not have manual controls. Nowadays sophisticated technology is being incorporated in the form of computerized controls that guide and ensure Engine performance.

Whenever you make a physical intervention the data pertaining to such intervention gets recorded in the memory banks of your car’s computer.

The computer uses the mapped data to work out the optimum control conditions in which the engine should function.

The ECU shuffles through the tons of data that come to it in the form of readings to decide the course of action that should be taken by the engine to ensure an ideal drive. The ECU tells your engine not only what to do but also how to do it. Thus the ECU in order to make accurate diagnosis on engine control utilizes stored data.

Even though you have made modifications in your car, the ECU still continues to get an input of the old data which is stored in it’s memory. This old data no longer is credible as it pertains to conditions that existed before the modification.

The input data to the ECU should pertain to the post modification situation of the components and parts introduced, while making the modification. This means that you have to erase the old data from memory and new data pertaining to post modification should be logged into the ECU memory by mapping in new readings. This is the reason why ECU resetting is essential for optimum performance after any modification has been carried out in your car.

The moment you have carried out the modification you should purge out existing data in your ECU’s memory. You should then feed in fresh data pertaining to the conditions that have come into existence post modification. The ECU has to operate on the newly acquired data as this new data reflects the true conditions post modification.

You should be well versed with the vital art of resetting the ECU of your car. You have to let your ECU adapt itself to the new situation arising out of the modification. Allow your ECU to relearn and perform.

Now therefore the step to be performed is to purge the old data and reset your ECU. Doing this allows it to adapt itself to new parts and efficiently perform post modification also. To reset the ECU you simply have to unplug the negative battery cable connection. Theoretically it is best to leave it in this disconnected condition for as long as you can. Practically leaving it disconnected overnight is more than enough.

After having left the cable disconnected for sufficient time you have to connect back the cable. Start the car and keep it running so that it warms up. This would not take more than 10 minutes at the most in summers. Once you have done this you have accomplished the ECU resetting. Shut off the engine.

You can now use your car whenever you feel like. ECU resetting is over.

You should remember a few points when doing the ECU setting. One important point that you should remember is not to reset ECU when using fuel additives or different octane fuel than you normally use. The idea is not to reset the ECU when using anything in your car that you normally don’t use. You should prepare the ECU to get adapted only to the conditions that it would normally encounter. This would also reduce the number of resets you will have to do to the ECU.

However if you are going to change the operating conditions on medium or long-term basis then you should reset your ECU. One such instance could be when you think of boosting octane.

Resetting the ECU when you choose to boost Octane becomes necessary because your ECU has a memory bank for octane.

This means that if you've been using lower octane, the response of ECU will correspond to lower octane with the booster matching lower octane performance.

The ECU response will continue to correspond to lower octane even though you have started using higher-octane fuel. This is because the ECU has not been reset for higher octane. Thus even though higher octane is in actual use, the data in ECU memory still corresponds to that of lower octane. This mismatch affects performance, as you are unable to derive the benefits of boosting the octane. Therefore you should reset your ECU periodically after filling up full tank in order to ensure that ECU adjustments for its octane memory are made afresh corresponding to the octane actually in use.

You can even customize resetting of your ECU so as to enable it to adapt itself to seasonal changes. Since humidity, air density, oxygen levels etc in air affect performance you could reset the ECU to adapt to these variables too.

The advantage of such resetting made to your ECU is that your car performs the best in every climatic condition. This lends versatility to your car- and all this at no cost.

Now let's dive more into the technical detail of tuning - but still keeping it simple..

Back in the good old days, the task of timing the ignition spark was performed by the mechanical distributor.

The greater the RPM, the more the timing would advance. It was clunky and mechanical but seemed to work reasonably well.

This did a sufficiently good job, but for the most effective power you would need to vary the timing to a greater degree than a fixed ratio advance curve.

The electronic ignition system was born giving much finer control over fuel delivery and spark timing. You ended up with a perfect spark timing only in a limited RPM band.

A complete map of variables was entered into the ignition program and the preset timing would be read from a table.

Now air temperature, engine speed, engine load and even control over turbo/wastegate control & fuel delivery rates means that precise management of the engine ignition timing is possible and you can achieve the maximum power output throughout the rev range.

What does ECU remapping do?

Electronic ignition allows the manufacturer to fine tune economy at popular road speeds such as 30mph, 56mph and 70mph where most cars spend a large proportion of their time. (Some manufacturers in the 2016 cheat software scandal have even created code to detect test conditions and run super lean to pass emissions limits.)

It is now possible to advance the timing if the throttle is wide open to give greater power or back off the timing when cruising at constant speed for improved economy.

Manufacturers do not want people breaking down, suffering premature parts failure or to get a reputation for uneconomical cars so they build in a wide margin of tolerance. Different countries use different grades of fuel and have varying degrees of extreme weather conditions, all these factors add to the fudge that has to be done to keep all the cars working well across the globe.

Each car that leaves the production line is also unique, some achieve 20bhp less and others can be 20bhp up on standard specs, depending on how well the components are machined and put together. So rather than put each car through a unique assessment and get a bespoke timing map, they adopt a standard one map fits all philosophy.

It is also a fact that manufacturers use the remap to produce different power versions of the same engine and get lower insurance cover ratings and better fuel consumption. You start to see the fantastic scope for improvement, when you add into the mix the fact that the average TorqueCars reader will be adding better performing components to the car, you have a really strong case for a remap.

Other things that the manufacturer builds in to their map equation is the possibility of user neglect i.e. infrequent servicing with items struggling like dirty plugs, bad leads, clogged air filter, partially blocked injectors etc.. The list goes on.

Who should remap?

Anyone who has added performance parts to their engine should consider a remap. If your car is a turbo model & has electronically controlled fuel injection, there are massive power gains on offer and TorqueCars would strongly recommend a remap.

What are the hidden costs or drawbacks? You will need to be prepared to keep the car serviced more frequently, and, sometimes decreasing the service interval by half. When you fill up you are also restricting yourself to high quality fuel and even high octane fuel if this was what the map was optimized for, and you must be prepared to replace components that fail due to the extra work they are doing.

When an engine is tuned to produce more power, you are also creating more stress and strain, so things will start to fail such as air flow sensors. Any weak spots in an engine usually show up a couple of months after a remap has been done. Generally the turbo/clutch weaknesses will manifest themselves clearly at this point. Also turbos can wear out, other major components like pistons and bearings will need care and attention and you will find that the clutch lasts a shorter time.

If you do not have a turbo there's very little to be gained by a remap alone - perhaps only a few BHP so TorqueCars' recommendation for non turbo cars is to modify everything else first (cams, pistons, increase compression, engine balance, air intake, exhaust, head work, bigger valves etc..) after these things have been done you can then consider a remap which will help you get the full benefit from them.

On the subject of turbos, (briefly though as we have a comprehensive article on turbos in the forced induction section), a remap will often introduce boost from lower down the rev range and because of this the turbo is running faster and hotter. In this situation you must let the turbo cool down a little before shutting off the engine, otherwise the oil will degrade and you will have an expensive turbo repair on your hands. Fitting a turbo timer will also help with this problem and keeps the engine ticking over.

Of course the amount of power you choose has a bearing on the reliability and cost of running the car. Many people go for an off the shelf remap which are on offer all over the country and typically cost around $260-$600.

This is better than the manufacturers map in that it uses tighter parameters but it is still a one size fits all job. If you are after big power gains and have changed major components like the turbo, waste gate and have done extensive engine work then a custom remap is the best option.

Switchable Remaps

Things have moved on and it is now possible to have a few maps stored which you can select from. It is typical to have a valet mode to stop the boy racers at the garage thrashing your pride and joy on the 'test run' to bed in the new wiper blades they have fitted. Then there is often an economy option to give very frugal fuel consumption, particularly useful when cruising on long journeys.

Then you have the 'sport' or 'power' modes which give lots of power and often require high octane fuel. TorqueCars strongly recommend that you get a switchable remap - it may cost a little more at the outset but you will avoid many of the pitfalls of running a high power remap all of the time by doing this and get the best of both worlds.

Some maps use the cruise control to choose a map, other companies offer handheld flash devices which allow you to choose a range of maps and upload these. It typically takes about 3 minutes to flash a car through the OBD port so is not an on the fly option.

Most people will run an economy map through the weekly commute and then go for a performance map at the weekend or a race map for track days.

Please do not confuse a remap with the little 'tuning boxes' you can buy for $60 which generally contain little more than a $5 resistor and often do little more than fool the car into thinking the air is cooler than it is. If it was really this easy to get more power from a car then the manufacturers would have already done that themselves.

Some cars are not easy to remap, I remember that the Rover MEMS & Toyota ECU's are a case in point. The Manufacturer holds the key to the ECU and locks their Map into their firmware. Some ECU's are simply not reprogrammable. So what can you do? Is there an option? Well thankfully there is and they are called piggy back ECU's or aftermarket ECU's.

Piggy back & Aftermarket ECUs:

Piggy back ECUs connect between your existing ECU and the engine sensor inputs and outputs. All work slightly differently and apply some or all of the following combinations.

Some will adjust the sensor readings such as air temp, engine speed, crank position and effectively lie to the standard ECU forcing a more aggressive timing. Some will actually perform their own calculations and take over control of some aspects of engine management like turbo waste gate control and ignition timing.

Tuning boxes are relatively new and these alter readings going to and from the ECU giving extra power or economy.

Aftermarket ECUs are often direct replacements for the car's ECU and will take over all the functions associated with it. They are generally faster and able to cope with a wide variety of additional factors such as water/methanol injection and a turbo timer.

Be wary though, as some piggy back ECUs and aftermarket ECUs do not include knock protection. If this is the case then set your timing conservatively and use high octane fuel.

3 Typical Questions When Attempting Car Tuning:

1. Should I get a 'one size-fits all'?
2. Should I get off-the-shelf chips like (Mugen, Jet, Spoon, Skunk2, Comptech, Neuspeed, FF Squad, Inline4, Power XS, Bayou Performance). Or Dinan ECU - which are 'best guess' chips?
3. Should I get one of those chips I see for sale on eBay all the time?

So here's the answers to them:

First, don't chip too early
There is no point in getting a new ECU program early in your engine build up and then later upgrading to bigger lift and duration cams, or larger injectors, bigger fuel pump, or an aftermarket IM/bigger bore TB , etc. , since these parts just render your 'new' ECU program obsolete and useless (ie. any power gains from the chip are eliminated).
So please do not get your chip reprogrammed just after i/h/c/e , if you later plan on going for bigger & better things in the future. It's supposed to be one of your last modifications and not one of your first, to prevent the need for multiple chip reprogrammings after each addition of a new modification.
The reason you see so many chips for resale on eBay?
Other enthusiasts made the mistake of buying a chip too early that was not programmed correctly for the unique way their engine package breathes. It made very little power for them , or likely made their engine run too rich, or both. They are now trying to recover the money lost from an obsolete or incompatible chip.
Then there are the programmers who take advantage of import enthusiasts who do not understand the performance difference between a pre-programmed, mail-order chip versus a chip tuned and programmed on your car at a dyno. They are selling them based on the attractiveness of convenience for unsuspecting people who don't have a local programmer and dyno, the hyped hp gains from the magazine articles or ads, and a lower cost compared to other significant hp gain modifications, like cams or an intake manifold (IM).

Second, What does an ECU do and what am I doing when I get a new chip ?

The ECU controls:

• the fuel map (ie. program commands for how much fuel to add at each rpm) and sequential firing of the injectors
• ignition map (program commands for how much spark timing to advance or retard from the baseline ignition timing you set at the distibutor cap at each rpm)
• VTEC switchover
• Redline
• Speed limiter (JDM and European models)
• Knock sensor warning
• Second O2 sensor CEL warning in OBD 2 and OBD 2b cars for testpipes and high flow cats and closed loop operations
• Activates the opening of the secondary runners' valves based on the IAB vacuum input, if you have a dual stage IM (eg. 3rd gen. GSR)

The ECU also activates your other CEL error codes and controls A/C & Idle/EVAP inputs/outputs.
When you get a new chip, the programmer has changed the program's commands of the ignition map and fuel map in response to a change in air flow and rpm (ie. both are indicators of 'engine load'). The amount of ignition timing and fuel delivery is changed for a given air flow and rpm compared to the stock program. The programmer can also remove or inactivate the sensor CEL warning codes and move the VTEC point, redline, and speed limiter points to anywhere you like.
What do these ECU program's commands look like?
Example of a 3 dimensional ignition table of program commands (or 'ignition map'):
Manifold Absolute Pressure or MAP which monitors air flow (Y axis), RPM (X-axis), and Ignition Advance/Retard from Baseline Timing (Z-axis).

There is also a 3-D fuel table (or 'fuel map') which has Intake Manifold Pressure (Y-axis), RPM (X-axis), and Fuel Values instead of spark Advance (Z-axis).

The program commands can be entered on 2 dimenional tables.

Example of a 2-Dimensional fuel table's commands during a GSR's VTEC cam lobe operation:

RPM down the Y axis to far left, MAP (mBar) across the top row, and fuel values for the injector duty cycle in the table cells.

Third, 'Best Guess' programs are not as good.

An 'off the shelf' or mail order ECU is a programmer's best guess at trying to make a program that will fit as many different engine combination of mods as possible..that's why I call these 'one-size-fits-all'. These usually get you in the no gain or 5% disappointment gain ballpark. You will not get major gains with these 'best guess' chips. Save your money.

So you want to make major power gains (ie. 13-15% or at least 7 whp from midrange up) with an ECU reprogram?

Please get a true custom chip instead, programmed on YOUR unique car with its own combination of mods, on a dyno using a wideband exhaust O2 sensor/Air:Fuel Ratio meter. This is the only way to go, if you are serious about getting the most out of a computer program upgrade for a street/race setup. If you got your chip by mail then, please understand that you did not get the most out of it..even the custom pre-programmed, mail-order kind of chips. The only correct way is to do the reprogramming on the dyno. And this leads us to who do you go to?
If you are lucky like me and have a couple of local programmers with Honda experience near your town, then your local programmer will go with you to the dyno and work his experience in tuning on the laptop and EPROM or EEPROM burner.
If you do not have a local programmer or race shop that does programming, then I strongly recommend getting together with some friends and investing in a Hondata Stage 4 or P200 system. It allows YOU to tune YOUR car on the dyno or at the track using elapsed times between known rpm points.
It comes with a chip burner, chips ($25/each), emulation laptop capability, instructions, and tech support. Investing in a wide band O2 sensor like the MOTEC they sell is also a good idea. This takes the guess and disappointment out of ECU upgrading.
If you want to go at this alone, then an AEM EMS is worth looking into, since it has base programs and laptop emulation. This is a serious investment for serious people.

If neither of these appeal to you and you insist on getting a mail order chip knowing that it won't be the best program, then stick to the known programmers (PM me if you want recommendations from people I've known who do a decent 'best guess' chip). Most people who buy a mail order chip usually have a piggyback tuning box, like an Apex fuel controller (SAFC or VAFC) or Field SFC VTEC/fuel controller, and use those to further tune the fuel delivery on the dyno with a wideband O2 sensor.

Chip reprogramming at the dyno requires a wideband universal exhaust gas oxygen sensors (called an UEGO that you can get from dyno shop or race shop) to measure air:fuel ratio at each rpm. Expect at least 3-4 hr dyno time minimum to tune these even if you are experienced at partial and wide open throttle fuel tuning.

Other systems to consider are the Motec M4, Apex Power FC, Accel DFI, SDS EF3, and Electromotive Tec3. Compare processor speed (16 bit, 16 MHz versus 32 bit, 33MHz ), available baseline programs to get you going without startin from scratch, sensor compatibility, emulators availability, and a good track record for tech support/customer service (not just whether they have one or not).

2. Why an 'off the shelf' mail order ECU will disappoint:

SDS and Hondata agrees with me that the best way to rechip your computer is to program your ECU instead on the dyno on your car rather than buying a previously programmed 'best guess' chip made to fit as many different engine packages as possible.

Here is some very good advice when buying a pre-programmed , 'mail order' performance chip from SDS' website that I have found to be true:

Be careful. Some unscrupulous programmers will promise to sell you a 'Mugen' like chip but in reality, all they have done is moved the redline higher and removed the CEL warnings. The advice to stick to known reputable programmers is wise, if you plan on mail orders.

What about standalone computers like a Hondata instead of a redone chip?

3. Some Basic ECU Info for OEM Honda ECUs

This is a brief introduction on how to tune a sample car map file using a good ECU HEX editor like TOAD.

NOTE: This is only a very brief introduction to tuning. There are many forums online on how to edit map files.

STEP 1: Download the stock ECU load from the vehicle. This image is the raw data from the ECU memory and is the application and Operating System code for the ECU. It controls how the car runs. Above the code area you will find the Constants and Maps, among other things.
Take a look at the figure below..

In the hex dump window you see a series of highlighted bytes, 43 7A 00 00, and in the Inspector window you see 'Float 250'.

This is showing a map or constant value, in 32 bit floating point format, of 250.

The next series of 4 bytes, 43 FA 00 00, is a value of 500.

A value of 00 00 00 00 is a zero value.

Notice there are lots of 32 bit floats in the area of memory. This is part of a table.

The 20 values shown are:

250, 500, 0,0, 9, 800, 1200, 1600, 2000, 2400, 2800, 3200, 3600, 4000, 4400, 4800, 5200, 5600, 6000 and 6400.

The values 200 and 500 are not RPM based on the magnitudes (RPM would not normally be lower than 650), the values 800 thru 6400 are most likely RPM values used in a lookup table or map.

What is a Map? Look at the array below..

The numbers in red represent RPM values, the green numbers represent Mass Air Flow and the numbers in the yellow matrix represent fuel injector pulse width.

The longer the injector pulse the more fuel gets injected into the rotor.

To find this table you would look for ascending RPM values, ascending MAP values and many fuel injector pulse values, RPM X MAP numbers, in this case 13X9. This is a purely hypothetical MAP for illustration only.

Just Autos Hilux Tune 2017

Going back to the ECU hex dump, the ascending RPM numbers could be the start of a fuel map, or it could be a timing map, or possibly a map to control oil injection, at this time we don't know the definition of that map.

To find a Constant, you need to know what to look for.

An RPM limit would be a 32bit float at 9000 for a standard transmission car or 7500 for a automatic.

You would do a search for '46 0C A0 00' to find all values of 9000.

Pick one and change to 8000 and see if you hit the RPM limit.

Not all values are stored as floats, there are also single byte values of 0-255, unknown if 16 bit integers are used.

If its a question it is followed by two numbers; one for the position of the line to go to if the user enters 'no' and another for 'yes'. The program works fine until the user inputs 'no' for a new animal(updated animal) after he enters yes for a new question(that he entered the last time to differentiate between animals). The program enters the file data into an array of structures, with the animal and question in the same variable(question) and the bool isAnimal tells me whether its an animal or a question.

Once you take a look at the MAP area in memory, you will see it's nearly all floats or byte values.

ECU Flashing / Programming / Tuning / Chiptuning Resources:

On the last note..

Even though chip tuning is possible with any ordinary HEX editor (as described above) — the fact is it can be very time consuming, tedious and error-prone.

That's why if you're serious about car ECU chip tuning — you want to look into dedicated ECU chip tuning software like TOAD. Software that not only provides HEX editing capabilities, but can also visually map out cars ECU map into sections.. without you having to look for them manually. This means you can tune a map in minutes vs. hours.. and without making any mistakes that could potentially render cars ECU chip useless. Check out the software here.
