Well im not boosted but i know alot of the boosted ppl would know about safc's and what not.

Anyways, I have a SAFC installed on my 88 accord. Its obdo.
I have all the wires hooked up and the rpms do not read correctly. It jumps constantly as well as readin 1 or 2k rpms high.

Example, at idle(1100rpms) the SAFC reads 28xx-35xxrpms but it jumps all in between those rumbers. I have the Green wire on the safc hooked directly to the - coil terminal. Any ideas on what could be the problem?
