Fueling is controlled by Maf Frequency, and ECT's, and IFR tables. For the 5th time Maf frequancy isnt effected by Intake air temp sensor "chips". Maf frequancy is controlled by ACTUAL AIR FLOW. Im not incorrect. ZZ Performance. Look at zzp's race pellet its the same thing. Ive been tuning my car for 6 years with HP tuners and been scanning parimiters for 6 on it. I know a thing or two. Only thing the Intake air temp sensor will do is add timing.
