I got two A9L mass air computers as I converted my 86 gt to mass air. One seems to do what its supposed to as far as correct voltages at tps, priming fuel pump ect...the other one has the fuel pump running constantly (doesnt shut off once it primes) but it responds to throttle and runs way better. What to do??? Im tempted to just go back to speed density. I have the old computer. Also, I put an old rebuilt SROD tranny in that doesnt have the VSS on the tranny and didnt run those wires...Any suggestions? Oh and my motor is bored & stroked to a 347, voodoo lunati cam, trw flat tops, eagle rods ect.
