Well i was installing my trick flow intake elbow and i noticed that one of the wires on my stock MAF sensor was broken. I soldered it back on but im sure thats not a good idea. I was wondering if i should just buy an aftermarket MAF sensor, either GMS or JET. I asked my dyno tuner and he said that he could just turn the MAF sensor off and tune it with the MAP sensor to save me a few bucks. He said it would run just as good maybe a tiny bit better. Is this possible or shopuld i just stick with a MAF sensor.

 

You can get another stocker.... but I do like the idea of doing a speed density tune and then plugging the MAF back in. It gets the WOT dead nuts.

You could use a scanner to judge whether it is working correctly. Maybe your repair is adequate.

 

Has anybody ever switched from a MAF tune to a MAP tune? How is it? Does it idle as smoothly? Is it as reliable? Is it as fuel efficient? And how are the WOT runs. I really have no idea what is involved here, so help me out.

Also my tuner said that he has no problem tuneing with an aftermarket MAF sensor so im thinking i can hopefully just find a cheap used GMS or JET MAF. I mean there is probably a reason GM switched from speed density in 93 to MAF sensors in 94. Let me know what you guys know/think.

 

Aftermarket MAFs are a scam so stay far away from one. As far as the SD vs MAF debate all I can say is you've open a BIG can of worms with that question.

 

On Vehicles With Both A Maf And A Map Installed Your Computer Reads One Or The Other If One Fails.

 

Does anybody have any info on a MAP tune, cause if i dont have to buy something new i dont want to.

 

I dont know what you want exactly. On a dyno its all the same... make fuel adjustments in the PE table. For part throttle driving you manipulate the VE table for your desired results. The end result is always the same but the MAF kinda simplifies the tuning a little.

 

Well im going to have to replace my MAF sensor and my tuner says he can tune around a GMS so i figure since it outflows the stocker by 47% i will go that route if i can find one relatively cheap. Or somewhere i read that you can use a ZO6 (85mm?) one that is adapted to work with LT1's. If anybody knows anything about this let me know.

 

Also does anybody know the difference beteween the regular GMS MAF sensor and the one tuned for a CAI.
