The only reason I asked - is you only joined ASN yesterday a day after Thomas's thread, although I "lurked" on these forums for a while awaiting some inspiration too. I certainly am no expert in the ECUs but my little understanding is ME7.5 controls the components to achieve the "numbers requested" and M3.8 reacts to the values from components to try and work out what the numbers are - making any meaningful hobby modifications an "expensive" <-- not in money but time and fruitless (dangerous) experimentation. When I had my 2003 Kia Sedona I bought essentially a variable resistor which turned the diesel pressure up and that made a V6 3.0 CRDi 15% more powerful than before? but the other day I told my ME7.5 I wanted a maximum of "210" (whatever's) @ 5500RPM @ 100% load which equals about 21PSI and said I want the car to try and get 0.83 Lamda - and that is after a couple of hours of reading? 3 additional settings later I have set a 2 step launch control, I was told don't touch a PID as I will not know what to set properly - this is why people are not fans of "difficult" / "black art" tuning.
