Hi all,

I'm looking for some help to correct my map.

My idle is going up and down continuously when the fan2 limit is reach. The idle is perfect with fan1 on.
I've tried to adjust rev/idle parameters but without better effect. Also tried to adjust the idle screw ...

My engine is mainly stock, only HKS downpipe and Apexi power intake.

Is it a known issue ?

Thank you

 

Have you checked/adjusted tps?

 

Yes, TPS is good.

I've heard about a screw under the throttle body to adjust idle, any ideas about it ?

 

try to post pics if you can, sounds like an electrical issue
