i don't suppose you can measure the impedance of one? if it's reasonably close to or higher than a GM unit, there really isn't a reason it couldn't be controlled. it's almost certainly capable of running at the 80Hz rate that a lot of the OBD1 ECMs control them at. I think the only time they're run above that is at 160Hz for the initial key-on positioning.
I don't have one to measure but with your info and my thought that it should work I have ordered the throttle body that uses one. At worst I will have try and adapt a gm style.
have a year/engine/model that it's intended for? I may be able to look up the specs.
It'll work, but the pinout is typically different between GM and Chrysler IACs, even though they appear to be physically identical.
If for some reason it doesn't work, a GM IAC should drop in place of the Chrysler IAC.
The iac is what comes on a holley terminator throttle body. The manual indicates a chrysler iac and it does have a pinout diagram. Also good to know that a gm iac probably will fit in its place if I can't make it work.
I have run a IAC from a jeep 4.0 with a 16197427. I just sat there and swapped the pins around until I found a combo that worked.
Yes, Holley uses Chryco IACs, so you definitely need to change the pinout. I ran into this with a friend's 496 Pontiac that we installed MS3Pro and custom fuel injection setup on that used a Holley throttle body.Quote:
