Find someone normal, who is not completely clueless.
It's literally ctrl+c ctrl+v 2 maps in the sw.
And it's retarded exactly for the reason of having to fuck with immo. Not to mention buying a whole damn ECU for something that takes a competent person 15 minutes!
This thread here is a
perfect example of the
XY problem.
Thanks for wasting everyone's time.
I figured the two maps you meant are KFKHFM (correction factor for HFM) and MSHFMTPH (massflow as a function of period). So I transferred them from a TTS binary. And it worked: the car starts and idles just fine, the MAF reading reacts to throttle and I get no implausible signal DTCs.
However, what worries me and what is the entire reason I chose the "retarded" approach, is this little bit from the wiring diagram of TT-S:
TT-S MAF uses 4 wires, as opposed to 3 wires in 6R. The extra wire on the TT-S version goes to pin 42, which is likely "Sekundärluftrückmeldung (Min HFM)" (as per MED9 FR). I tried searching the FR for it, but the only hit is the pin out section. I'm guessing the extra wire isn't the temperature correction signal
Also, it turns out the immo fix is really easy, just 4 bytes. However, the real problem seems to be CAN coding, because even though TTS software allows the car to start and run fine, I get U0146 DTC.
