Did you mean to say you set it to an 8 cyl correct? If so, it might not be that the new tach is off but the factory mass produced tach could be off is more likely. Either way I would def make sure you have it set for the 8 cylinder.

no the ls1 tach runs off a 4 cylinder signal. not like your old school v8s that ran a 8 cylinder signal i thought. so i set mine up for a 4 cylinder.

In addition, Has the tach been adjusted to read a 5v square wave signal? I had to send mine back to autometer so they could reset it to read the ls1 signal properly. It took like 2 weeks and I had it back.

when I got mine it was configured as the default which is 12v analog sine wave signal. LS1 uses a 5v square wave signal. Call autometer. They should do it free of charge. I just needed to pay for shipping when I did it.
