Nowadays sophisticated technology is being incorporated in the form of computerized controls that guide and ensure Engine performance. Modern day cars do not have manual controls. This is the only way to ensure that you get the best in both driving as well as handling. For your car to deliver it’s best performance you have to keep it in a fit condition at all times. PART 2 demonstrates example how to program ECU via HEX coding software.įirst a basic beginners guide introduction into world of car tuning and what you need to know:

You'll first need to get familiar with this information before attempting to code (as discussed in PART 2). PART 1 of this article will talk about basics of ECU. Intro Guide to Do-It-Yourself ECU Map Chip Tuning / Programming / Flashing (Using HEX Editor)


That's another matter but hopefully this gives you an idea of the main difficulties you'll face should you decide to tune the car.Posted by Alex (Im) E. To really get good you'll need to understand assembly language for the CPU in your DME. You will have to find the relevant ones yourself and although you will find guides, likely for pay, they will never match up perfectly and you'll be doing a lot of work at first to find things. All the tuning data to run the engine is contained in several thousand individual tables of numbers called maps. If you're not good at it, well, you'll probably give up lol. Assuming you can find enough info and motivation to get going, it will probably take you months to make a halfway decent tune even if you're good at it. Learning ECU tuning particularly with late-model factory ECUs can be tricky because the few people who know a lot about your ECU, won't talk about it. However, I get the impression you've never done anything like this before. If you want a N55 you'll need to invest several thousand in legit WinOLS and a legit programmer. If you're getting an N54 I think you can easily tune it with pirated WinOLS and an inexpensive Chinese clone cable from ebay. There is other editing software but WinOLS is the standard and it's very powerful and easy to use once you learn it. You need WinOLS and a programming cable like cmdflash.
