alpha-n and fuel trimming

EVANGELOS · 30-03-2011, 08:15 PM

Hello ,

I own a normal M3 E46 with an MK airbox and an alpha-n reprogramming on the stock ECU.

Although my car is running very nice , I have been checking through the GT1 module the adaptation values and I have discovered that the dme is making NO compensation what so ever on the injection time (both additive and multiplicative adaptation values are ZERO).

I think that the MK alpha-n programming has "locked out" the fuel adaptation routines ...

my question for all the csl owners is whether this applies to the STANDARD alpha-n programming of the csl , or not ???

I mean does the csl make fuel adaptions (have you ever checked) or not ???

thanks
