Gm maf and ecmlink cable problem

[Jpaulson64]

So i recently installed an hx35,gm maf with ecmlink gm maf cable and fmic and also deleted the evap and egr on my 91 talon tsi auto. I have ecmlink v3 lite still waiting on v3 full but heres my problem, cars runs super rich and is really boggy and sputters out after 2k rpms and also when i hook the ground up from the gm maf cable the car dies? Anyone have this problem?

No check the wires again, running rich due to what might i ask, do you have a wideband, stock injectors or aftermarket.

Runnin rich due to the gm maf i believe i got it to run without the sputter but now im fouling plugs out and my afrs r 10-12 while crusing and on deceleration im hitting 13-14 afr witch is terrible im wondering if im unable to tune the car until i get v3 full?

The gm maf is causing you to have more fuel to run rich is that what you are saying? You should have to use v3 to tune the car, sounds like something esle besides your version or gm maf, injectors perhaps.

Ditch that pos gm maf go speed density.. pm my1gdsm if need a good tune at a good price..

Sd the way to go, im headed that direction next after turbo upgrade, and more fuel to run e 85. I hate the gm maf.

Ya im really thinking about it ### does it consist of just the iat sensor the map sensor and ### else? How do u install it?

Check out ecmlink.

well my theory was right, i got my link upgraded to v3 full switch maf types to gm 3in. and it started right up still having some tuning issues tho really doggy just cruising around getting like 12.8 degress of knock thinking its some phantom knock or some sort of timing issue if anyone with gm maf experience could give me a good base map set up that would be great i can also post a log up so u guys can see wats going on

You do realize the GM MAF cable only works with v3 full, right? Basically your ECU was seeing no MAF signal.
