GM 3"& MAFT. Need Tuning Help ASAP

[91DSMdave]

1G talon tsi awd.

Ok. So i just bought a 3 inch GM Maf and MAFT. now i need to know what to get it all set to.

stock everything fuelwise, front mount 3 inch pretty much stock. no wideband, or metering system of any kind. I just need to get it set at a ballpark level so the car will run just as good if not better.

From what i have gathered, dip switches are all off and the base knob is to be set at 2. im lost on everything else. Translator is the 2.02

please help me. I have searched and have gotten no clear answer cause most everyone is tuning these for bigger injectors.

thanks ahead.

the instruction tell you everything, but i wouldn't recommend changing it from a stock setting till you have some way to measure knock.

for stock 450cc injectors it should be set aux =0 base =2

the other three adjust airflow calibration for idle/mid/WOT

but every gm maf will read different( at least all mine have) so theres really know correct way to tune it without a logger/ wideband

so you are saying that on my stock setup i have now run all dip switches off, aux 0, base 2, and leave everything else at 0???

yes i would leave them all off, but its hard to say what you should have the idle/mid/wot set to because every gm maf will read different

Mines all over the place set for stock injectors. Had to lean out all the knobs aka counter clockwise...

Yep every car is different, mines are everywhere too, read the directions everything you will need to get started is right there.

Set for 450's. If it runs good then leave it be. Dont run more than stock boost or go WOT IMO, until you get a WBO2 to monitor afr's and a logger to monitor knock.
