Need help with leaning AFM on Voodoo 2 Kit (92 NA6)
Idk if this is the correct sub. Sorry mods if it isn't.
I have a 92 NA6 with a Voodoo turbo from FM.
Basically my problem is that when I'm in boost my air fuel ratio meter is saying 10-11 which is great. But then it rises to 14+ which is very lean during boost.
I have doused it in brake cleaner trying to find a vacuum leak. There is no misfire, but I changed plugs/wires/coilpack. I rechecked my tune on the Voodoobox. I changed the 02 sensor (not that it matters, Voodoo takes over once in boost), and I changed the airflow meter. I've also done fuel pressure tests and fuel pump is strong. Changed injectors (stock to stock).
I have a suspicion that the air flow meter doesn't like being upside down, but I haven't tried putting it right side up cause that's FM's way of configuring it for the turbo. But I haven't had those issues before. I've tried the AFM from my other car to compare and it does the same thing.
Again, I will have perfect air fuel until about 3 seconds into the pull and it'll lean out. Boost pressure where its suppose to be. No change in performance when it leans out either but it's obviously not a good thing to be leaning out during boost...
