Hello, I have 91 Sprint, with a 92 G10 motor in it that came from a 4dr auto. Mine is manual but with the auto ecu and wiring harness. I have a equus tach in my car. Now here`s the thing Ive searched the threads and the guys are hitting the limiter at 6500-6800 rpm. I'm hitting it at 5500rpm according to my tach. Would it be the auto ecu that has it set to that? And is there a way to remove it? Or could it be just the tach that's not reading it right (I doubt this because it shows my idle correctly which is 750rpm)

Thanks guys

Does the Tach you are using have a 3 cylinder mode. I have yet to find one that is designed for the three cylinder, Besides the factory tach's.
