in that case , ill leave it and watch it, cause if the IAC was hunting the revs would be also .

yup running ok besides needing throttle to keep it from dying when i start it. Just very peculiar why the IAC is not affecting anything when it goes from 0-100 and back to 0

Is it doing it random, or from cold to hot?

its pretty random honestly. I’ll do some more riding and keep an eye on it. When i’m using throttle it seems to be in range somewhat. Ots mostly when idling i believe

Took intake off, went over wiring and changed out map sensor with one off the old intake. Iac steps were low but didnt “hunt”. Turned out throttle blade screw and lowest its been is 16 so far. Idles a bit more consistently too 🤞🏻🤞🏻
