AFC Settings

Can anyone explain why everyone says to set the AFC to 2 cylinders on DSMs?

I had to set mine to 4 cylinders... on 2 it was showing double the rpms... on 4, it is fine

I have never heard about that.
Mine is set to four and everything is perfect???
I would like an explanation about that one too.

do you have an eeprom?
I noticed you're a 2nd gen...

Mine is a 1st ('91)... I did notice that my ECU stays on for a/b 30 seconds after the car has been cut off... but my friend's has an EEPROM and his cuts off instantly... his is set to 2 cylinders... is that the difference?

mine stays on for a little bit too...i dont remember what the afc is set to though.

Mine is set to 4 cyl. Travis had the same problem. I believe his is cut to 2 also.

no mine was set at 6 cyl and it was showing duble rpms.( it was set at that upon instaltion) when i changed it to 4 its fine.

Ahh... Another one set to 4 and working fine. I dont know!

when I turn off my car my ecu stays on for about 10 secs. No eprom, No problems. (no woman no cry).
