Well as I know at this time almost all ECU's (except those from oldtimers:)) have EEPROM so they can be flashed, but as I also know not all can be flashed via OBD, but they need to open the ECU and flashed it in boot mode. Cheap tool to flash most of the ECUs is Galletto, there are tons of...

I don't now thats why I post my question on this forum as I thought that forum is the right place where people share its knowledge. I didn't state I'am not willing to spent no money, I just wanted to say not like 10.000€ on professional equipment. We all know about Galletto and cheap alike...

you definetly did't understand me! I sad that I am no fool that I will experiment on my 40k€ BMW 530 d. This car has been chiped allready at the local tunner for 700€ (although I thing half of that amount will be enough for a generic remap). But it is true that after a generic remapping tunner...

on the fly - sorry but I am all new about the expresions. the intention is not to gain HP, but to experiment and learn about remapping and the desire of doing that is I my personal fun. If I want a HP gain I'll wisit first local tunner. Sure you don't expect that I will test that on my new 40k€...

Hi, car has these ECU my question is wether it can be flashed via bdm or boot mode or it cannot be flashed at all. Also tell the difference betwen bdm and boot mode.

Hi, can someone explain the difference and by which option ECU form the pic below could be remapped?

I thought that merely remapping is quiet universall. 2000+ OBDII I really don't wish to work physicaly with ICs on the circuit board, I preffer flashing method via OBD socket. Ok thanks for that one I will have a lok at it.

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 also know that when you want to make a useful remap you need a dyno and it is helpful if you even...

And where do you prove that free isn't worth a thing? Can you maybe be more specific and list a few things that didn't work or wasn't good. As far as it is all hardware interfaces are just a single 8bit MCU that converts electrical signals of two different communication protocols. And...

Whoa:amazed: I usualy read the question and then give an answer. who does ask for advises??? Cars and its oboard electronics is not a rocket science. You can't destroy ECU or engine if you don't hit with the hammer on it. Finaly if your changes are not good you can allways write the stock...

Which ecu remapping software do you use or suggest? I found two freeware programs; ECUedit that seems to be only for Subaru and Mitsubishi cars and ECUflash that seems to be an application just for read/write not also modify.
