MAF tuning

[doubas]

Hello,

Coming from an OEM ECU chipping community so standalone tuning strategy is a bit new.

This is my first post on this forum although i read and learned a lot from you guys, so thanks!

I have an 1.8t AGU stock internals engine with T3T4 turbo/lightweight pulleys, CAI, 3" exhaust, Genesis2 630cc Injectors on VW MK4, and managed to run the car on MS3x with MS3 pre-1.5.1 beta 2 firmware. Although it needs a lot of tuning but it runs ok for now. Need to try tuning using an Audi S4 OEM MAF 76mm id as primary fueling since I had great results tuning it to my OEM ECU.

The problem is when I set the fueling for MAF, the car does not start and run pig rich (pulsewidth go to 60+ on cranking) no matter how I lower the MAF/volt table. I also tried loading the mass airflow/MAF volts table from Audi ECU but same issue.

I'd really appreciate if somebody experienced enough to shed some light or point to the right direction.

Many thanks in advance.

You have not configured TS to use MAF.
