Posted by Alex (Im) E. On 21 February 2013 01:09 AM Intro Guide to Do-It-Yourself ECU Map Chip Tuning / Programming / Flashing (Using HEX Editor) 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). 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.
