The ZC Conversion 88-91 Si/HF ECU to "ZC"

Easily convert the ECU you already have to run your "new" motor. Everything from fuel, timing, to idle, rev limits, and even A/C control is reworked to function just as it should. Dyno and road tested to ZC ECU specification! Customer Feedback: " Right when I started the car the difference was noticeable. The Engine ran smoother and the idle was stable all the way thru warm-up, and of course no more of those damned flat spots. The very best part though was that I'm not getting the O2 codes anymore that the 89 teg ecu had been plaguing me with. Wonderful and great!" "Starts WAY easier than my 88 ZC computer. One anomaly that my ZC ECU has (a tendency to vary the rev limit) it doesn't!"
