Latest IAC adjustment instructions from FiTech turning both front and rear blades
#11 · September 27, 2022, 8:18 pm
Followed step-by-step and IAC still sitting at 0 more time than jumping up to 3 but only for a flash at 3 then back to 0 the screws are back off of blades completely. Any other ideas?

I am wondering what's happening. The only thing I can think of is double check that the blades are completely closed and not stuck open or held by the throttle wire. Force them close with your fingers and see if there is a change.

Thanks FiTech seems to want you to really work when it comes to tuning , even the initial setup took some searching . I sure hope tuning can change my mind on this efi system. I have literally hated this thing from the day I opened the box.
