Hey everyone
I have a 2010 Camaro with a torqstorm supercharger that seems like no matter what I do with my maf calibration I'm still pretty lean or rich no matter how many times I log and make adjustments after.
Originally I had the car Dyno tuned after installing the supercharger and supporting mods(fic 850cc injectors and zl1 pump) the car drove alright after that but since then I put 2" headers and cat delete so I figured now would be the time for me to jump in and try to make the changes myself. So after pulling the tune from the Dyno shop it seems like all they did was a maf calibration and adjust timing along with a few other things. No vve from what I can tell. The car is running in maf only mode. Something I noticed right off the bat was that the injector data I had put in from fic was changed and isn't really close to what they had supplied. This seems like a red flag to me right away. Another issue is as soon as I turn off ltft my fueling is all over the place even at idle (.78 to 1.25) even worse while driving. I'm following the method from grg which seems pretty straight forward but like I said no matter how many times I changed the calibration it's pretty much doing whatever it wants. Even after a short drive I could be rich in whatever hertz range and a couple minutes later in the same range I'm now very lean. Is there something I'm missing or is whatever they put in my injector data causing me to chase my tail on this? I'm still very much new to this. I don't have access to my tunes or logs at this exact moment but I'd be glad to supply any tunes or logs in the morning if that will help.
Thanks everyone.
