Hello! I do wiring swap in my agu (m3.8.3) to aum (me7.5). I use standard agu non vvt chain tens and cam sensor pulse wheel (4 gaps). What i need to vvt delete? I do:

CDNWS changed to 0.
KFNWSE whole table set to 18.
ESKONF
Copied KFZW to KFZW2 and KFZWOP to KFZWOP2.

And i have problem with incorrect corelation error and my car on 1 bar ride like crap.  Huh Huh Huh Huh
Do i need one gap cam sensor wheel?

Holy , 17 kw cf idle stab is most definitly not good. Check your timing first. You need to use the VVT and the rotor and the sensor from the new head if you want VVT. You can code out VVT if you want but why when its there?

I am running AEB head with AEB cams and vvt.
