MAF-T vs Auto ecu

[DroopYeyeS]

I've not yet found anything on this topic, so it's time I asked. I'm wondering if the MAF-T assumes that the ECU it's talking to is that of a manual car by default. Were it's setting designed to be talking to an ECU that assumes 450cc injectors stock or does it make a difference. I ask because I'm dealing with an A/T car. The setup is the A/T ECU with a M/T motor. So the injectors are obviously not the 390cc's that the ecu is looking for. The issue I'm trying to iron out is this; If the MAF-T gets set to 450cc injectors to tell a M/T ECU that 450cc stock injectors are present, what setting do you start with to tell an ECU that is looking for 390cc's that it's 450cc's? Thanks for any help on this guys.

Wow I didn't even know they had to be adsjusted like that, I thought they where a plug and play system.

They are plug and play as far as making the GM Maf work on the car, but they are also a tuning tool. The MAF-T first gets set for injector size, then you can tune base, mid, & high trims. once you have it all set on your base map you can then move onto RPM tuning for WOT pulls. There is more to it than just plug and go.

Been a while since I looked at the ver. on the box but I want to say 2.0. I'm just getting ready to put it all back together after winter rebuild. This is an issue I was having before the tear down.
