I installed a mugen chipped ecu (thanks katman) and a skunk2 IM this weekend and my idle went from 750rpm to 1500rpm. I imagine its the mugen program. How do I drop it back down.
BTW the program and the IM are BEAUTIFUL. Low and mid are slightly stronger and vtec on up is sicccc! This is by the *** dyno tho.

 

Open hood
Disconnect IACV (plug in the back of the Intake manifold closest to the firewall.
Start engine
Turn screw in trottle body until optimum idle is reached. (screw is above the bore of the trottle body just slightly off center to the left. Slotted.)
Shut off engine
Reconnect IACV
Pull back up fuse to ECU and leave disconnected for 1 minute.
Replace fuse
Start engine and LEAVE ALONE for 5 minutes of run time to allow ECU to "relearn" the way all of it's components work.
