Hi again everyone.
I just put extractors,cats and an exhaust on my s1 vt v8 and now when its cold it will hesitate when taking off due to been lean for about the first minute.I think it is an enrichment problem cause its acting like a carby with the accel pump disconnected.(hope this makes sense)
So I was just wondering if someone could help me out on which map to change as I am new to maf.
Thanks in advance.

I had the same symptoms on my VS series 3 with the same VT engine many years ago but it wasn't related to fitting a new exhaust. It would occasionally bring up one of the TPS error codes. Tested the TPS and it was fine, but replaced it anyway. I ended up replacing the MAF and the problem was solved.
If you are able to log the air flow in any way, perhaps you could rule this one out.

Hope this helps.

Hi thanks brindo I will have a look at afm readings and see what I can see.
Cheers
