I made the following changes on my 1998 ITR:
-Mugen cylider hi compression head gasket
-Skunk2 stage II cams
-Skunk2 valve train+ti retainers
-STR 70 mm Throttle body
-JG Edlebrock intake manifold
-spoon header & exhaust
-Mugen ECU

The car doesn't idel ver well , cold its OK but when the engine is warm , it idels at 2500rpm or it doen't idel at all. Car goes very well , only a small hesitation arround 4800 rpm (too low vtec point)

Now I just tried mu std ECU and the ideling is PERFECT , only the overall performance of the car is not so good any more.

Any one can help on this one ?

What should be the ignition timing to get the best results ?

why dont you try adjusting the idle?

Maybe in the mist of installing all those parts, someone tighten your throttle cable too much, check it out. I know when I had my JRSC removed, they didn't adjust my cable, and my throttle response was slow as hell, then I tighten it again, but i tighten too much, and my throttle was going crazy.
