Okay, so I have a 90 with a T-28 Turbo. Now I first put in 326cc injects, but my car wouldn't run. Too big so I put in 265cc tan tops from 94, but my question is how do I adjust the idle being that I am a MAFer. I know you AFMers don't have any prob, but what do we do???? HELP

shouldnt have any problems idling 265cc injectors without touching a thing.

shouldn't have any problems idling 326cc injectors without touching a thing, however, it will idle rich.

shouldn't have much trouble with either size, the latter you may want to adjust the clockspring in the maf, is that info even still out there?

MAF sensors don't have clocksprings.

VAF sensors do, however.

Doesn't the OP's '90 have an AFM (with a clockspring) and '94+ have MAF? Or have I had this wrong in my head all these years?

Stock ECU, one AFPR before fuel rail, then a FMU 10/1 and AFPR after rail. 100 psi pump and 94 injectors. I put in 89 326cc injectors from a turbo probe, but I think they were died to start with because it didn't run. The 94 injects make the car run a little ruff, but I'm thinking that one of them isn't sealed to the manifold that good. Broken straw effect.

HEY LOL I"M DUMB YOUR ALL RIGHT!!!! CAN"T BELIEVE I FORGOT IT IS A AFM. So what can I run or how do I adjust it rich and lean. Is it where I pull off that top cap and pull that little arm back and spin the wheel???


Also, how much boost should I run at what PSI to the rail, and after the rail? I know NOOB stuff!!!! LOL

I think you need a couple ppppowercards on the fuel pump, and another adjustable fuel pressure regulator on the windsheild wipers.

But seriously why do you have a regulator before the fuel rail.
