No you don't need a dyno to make a useful Timing Map or any VE (fuel mixture) Table, etc. I'll try and answer each part of your post in turn. I know that it has a close and open loop mode, but I don't know if ECU determines outputs by including input data into equations or it simply search the output values from comparising inputs and outputs in the maps. The other request is that if it is not to hard that someone can briefly explain or give an internet link to an explanation how exactly ECU even work.

So I was thinking to buy a cheap Galletto ecu flasher but I will also need some software to play with maps.

My interest in playing with maps intent to be only as a hobby and I don't mean to realy tune cars, except that I will have to test my mapping somwhere and that will be my second car that is Seat Leon 1.6 (I don't know if its ECU even has OBD flashing cabability).īut I think that if I also load a new and tested code (bought online from example UCABLES for 100$) to my A4 2.0TDI it can't kill it, or it can? I don't know much about engine tunning but I do know that ECU as electronic device can't be damaged if you flash it (unless it has a safety switch that locks it from irruption). I used to program MCUs for industrial automatization and you can't believe how much can a single 8bit MCU perform in just a second, and BTW 32bit MCUs today cost nearly the same a 8bit, round few bucks! My personal opinion about 32bit MCUs in ECU is that this is no more than exaggeration like everything in todays car industry. I aslo know that not all cars have EGT sensor that can be wery helpful determing the engine conditions and from my engineering education I also know that too lean mixture raises the EGT and can damage the piston rings. It can takes a whole week to perform a custom chip tuning (by the words of my local tunner). I also know that modern ECUs don't allow real time programing, (at least I read about that and it means that every modification that you make have to be written into flash and tested on dyno). I also know that when you want to make a useful remap you need a dyno and it is helpful if you even have exaust gas measuring tool.

The software for this is around $1,000 and is seriously sophisticated.įor example: OK so just let me explain that I don't treat myself as any kind of expert regarding a tunning process, on the contrary I have never seen a tunner from a close working with engine electronics. I have experience only with GM,GMC, Chevrolet & Pontiac controlled cars that have LS1-B, LS2, E40, E67, E38, T42 & T43 controllers. PCM's, ECU's and ECM's are not just 64bit or 32bit. It is not much help asking a question without knowing where you are and what you want to achieve with whichever type of car. Which type of parameters do you wish to alter?įuelling, AFR, Ignition advance, Torque Management, Electric Fan Control, Injector Flow Rate, etc, etc. For which make of car?ĭo you want chip re-programming and replacement or.ĭo you want hand-held programmers type flash-tuning or software that you can down-load into a lap-top and to re-flash? How can you expect ppl here to help you if YOU are not specific NOT TO CORRECT when ppl try to be helpful. It's not required for me or anyone to prove anything. On a public Forum one can ask a question and you normally get opinions.
