Rpm on AFC

[killab443]

I just installed my afc2 and did the basic setup to get it to run with the car, I noticed the rpm is off by 500. My question is how do I fix that. The # of cylinders is at 4 and the arrow is goting to the upper right. What else car I do?

If the AFC is hooked to the tach signal to the ecm wire, it should be fine. Chance are the signal wire, ecm, and afc are seeing the correct RPM and you dashboard tach is off.

try setting it on 2clyinders, it will cut the rpms in half. thats what i did with mine.
