so ive been trying to figure out everything with the usb aldl cable. im using freescan and tts datamaster and efi live trial. my gas milage is around 13mpg combined. i dont really know what im looking for since i have no dtc codes, and im really wondering whats up with this car. i did have a tranny code a dtc 81 . im running a old 20k mile auto from a car that hasnt run since like 97 so maybe it has issues. the low reverse captive ball was removed when installed . i just think it shifts funny regardless. if i floor it from a 40mph roll it takes for ever for the car to shift and i swear it doesnt kickdown either.
so for a 94 z28 auto i dont know what the mass air meter should read or the map at idle and freescan shows my idle set at 550????!!! that cant be right... i think some one flashed my computer with a crappy tune along with the damn hypertech
