Curious...do you have the 3" or 3.5" GM MAF?

I had the 3.5 with 780's and it stated and ran great, I dont remember what setting I has it it. If you running rich then you need to make is seem like you have bigger injectors i think i cant remember for sure.

3.5 maf

 

[cruisintalonawd]

I would say you have something set wrong. Do you have the paper that is came with?

 

[thatblondechik]

There's your problem.

When I first got my MAFT I had a 3.5" MAF and couldn't for the LIFE of me get it to function properly. After much research (and headaches), I found that the 3.5" MAFs are damn near impossible to tune (might not even be compatible). Switched to the 3" and all my problems disappeared.

Searching for a thread that explains everything in greater detail.

why would I have no problems then?? So that must not be the problem

The 3.5" MAF's *will* work, but I think part of the problem with them is that they exaggerate the issues with running the GM MAF. When you shove a 2" intercooler pipe in front of a 3.5" MAF, do you really think the airflow is evenly distributed across the whole MAF? I doubt it. Tom at DSMLink says the output Hz can vary 30-40% depending upon what size pipes and adapters you use. How the MAF is mounted, and any bends near the MAF further add complications to using it that way in blowthru.

Why yours works is beyond me. I just know that when I was setting up my MAFT/AFC combo I could NOT get anything better than a hard rev before it fell on its face and died.

Switched to a 3" MAF and my problems disappeared entirely.

no i dont have the paper that came with it i have the base at 6 and idle at 2 if anybody has a better setting let me know also my safc is zeroed out

 

[thatblondechik]

I honestly don't see you having any luck with a 3.5" MAF. I tried for over a week and got absolutely nothing. Cruisin seems to believe otherwise, but that's just my .02.

 

[turbotalon31]

if there is anybody local will to take a look at it it would be very helpful im pretty new to this and got stuck when it cam to tuning

 

[thatblondechik]

Drive out to Western Pa...I'm sure I could fix it right up with a 3"

 

[cruisintalonawd]

well maybe I got lucky, and maybe it was because I was running a 3" intercooler piping

 

[turbotalon31]

i think found out why i have the translator set wrong i quess there is a new and older verison i have the newer 1 and had it set for the older 1 ill find out tomarrow and ill update them
