J37 throttle high cold idle
Posted: Sun Jan 14, 2018 11:06 am
I have installed a J37 throttle on my 06 supercharged TSX. When hot, everything works fine (idles at 800rpm no problem) but cold idle is very high, reaching fuel cut. I tried ignition retard when cold but this does not seem to work as intended. I guess stock ECU uses another throttle MAP when cold and even a small angle change results in high flow changes with this TB. Any workarounds Hondata?
