AFC # of cylinders

[1990talon]

Ok so I bought my car a couple of months ago and I just started to figure out the S-AFC and I noticed it is set on two cylinders should I set it to four or just leave it. It works fine and runs good what should I do?

Leave it at 2, if you set it to 4 it will cut your rpm display on the S-AFC in half.

Thanks is it suposed to be this way? Or is there something I can fix.

Ive read it shoud be set to 4cly with the arrow pointing up! Really it should be set at 4 unless this problem is ocuuring! RPM Signal off by half Because of the way that Mitsubishi triggers the ignition coils, this is normal. To fix it, just set the Cylinders to "2"
