The M3 unit doesn`t really have to be ''boot loaded'' to be reprogrammed.
The truth about the M2 unit is that these ECUs are incompatible with most of iaw decoders. A vast majority of an IAWdecoder programming hardware is simply cloned and doesn`t work correctly. Here i tell You why:
I just have learned my lesson about it.
I had a situation with a M2 ecu and tried to reprogram it with a cheap IAWdecoder clone, and that was obviously unsuccesful - programming session crashed - a programming software doesn`t close the data transfer session on the last part of write sequence, heavens know why - SIMPLY IV`e BAKED it UP , then i bought another one M2- BAKED UP AGAIN!!! , then i tried to cheat the central body computer on client`s punto using a M3 model reprogrammed to M2 software. That was a smashing setback - the client took his car on the road very content, then called me at the same day asking to tow the Punto back to the workshop - engine stopped for good. The remedy came on the next day, i bought an another M2 unit and took it to the guy miles from my town that have had an ORIGINAL iaw decoder.
After reprogramming using an original equipment the problem`s been resolved. I hope my story will save someone`s time and money.
