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.
