Hello, I finished the installation of my skunk2 IM, hondata gasket & JG 65mm TB

I also bypass the coolant for FITV but not for the IACV, the FITV is bolted with a rubber gasket between the FITV and TB,, this is my diagram:

Now my engine is crazy,

1) with stock ecu, the idle goes from 1000rpm to 1500 and raises another time to 1000 (as vacuum leak I think)

2) with crome stock map, the idle goes from 1000 to 3000, but when the car is hot sounds some high knock sound and voila the car mantains idle well at 900-1000rpm aprox.

Suggestions?¿ I revised vacuum leaks and I think all is ok, the circuit dont have air in coolant, and I put some hondabond in hondata gasket to prevent leaks.

Thanks

 

I burned another crome map with IACV disabled

and seems that the problem is solved,

but someone can explain me why with std ecu the idle fluctuate as vacuum leak and with the IACV disabled (but pluged) the idle is "normal" ?


"normal" -> in cold the idle is about 700 but when the car is warm ups to 1100rpm aprox

Thanks.

 

did you set the idle with the tb screw?

if not, enable iacv; with car runing unplug the iacv and set the idle screw to 550-600 rpms. shut car off, plug crap back in and see what happens
