Hey guy's first post here
Im very new to HP tuners and I am having a hard time tuning a LS3 MAF into my car.
I have a Duspeed intake and a LS3 MAF card in it. I pulled the Low and High MAF rates from a 6.2 to get started, it runs and I can drive it but my LTFT is like 24.2. I followed the tuning school book for tuning the MAF and got it down a bit and my AFR started looking better also but I hit a point where bank 1 and bank 2 are not matching up. Bank one can be like -6.8 and bank 2 could still be 20-24.2.
Is there a reason Bank 2 won't come down with bank 1. Note it is not always like that, sometimes the numbers will get within a couple digits of each other.
My car has a E40 ECM, dose anyone have some pointers or a base map i can use to swap a LS3 MAF into a LS2 car?
Basically if I can get a tune file I can pull some good MAF numbers off of that'd be awesome
My only Mods are Kooks LT, Catless, Catback and Duspeed intake W/ 160 thermostat
