My safc 2 is reading the wrong rpm in my 240 I have a sr20det
it started reading like 500 rpm at idle and my tach on my
Dash reads stock idle rpm and it will read 2500 at 4000 rpm I think
it gets worse the higher I go in rpms it worked fine until I changed
my oil and I had to disconnect my battery for some work on my
subs if anyone could help I would be greatful

did u set the car select and everything? u should double check it. maybe the memory got erased check it first.

Are you using the SR20DET settings on the AFC? youll need to make sure its the right sensor and sensor number. Also, it happens a lot, but people hook the wires up the opposite way.
