Having a hard time dialing in my IAC set up. Motor is running but having a hard time dialing in the Holley Term X tune. I am running a BBK 1792 TB on my stock intake. The only IAC that fits this TB casting that I know if is the mopar #4861552AC - which is what I am using. I realize holley primarily builds their product for GM applications and they have not been able to help me with the IAC settings, this is why I am reaching out here in hopes that someone has already figured out my challenge. So my question is does anyone know where to find the the power supply requirements and frequency settings for this two wire PWM IAC? I have been all over the internet and even gone into the dodge dealer and no one has been able to tell me. I currently have 12V power supply and ground to the IAC - it is working but is making a pretty substantial humming noise when engaged. IAC is reading percentages at it should on the software digital display. Once the motor warms up, this is where the issue is as it does not want to stay at idle. I have to adjust my idle screw to 1200rpm once the motor is warm to keep it running. I have had a professional tuner work on this remotely as well and he thinks it is most likely a wiring issue. If I knew the requirements of this specific IAC I could ensure it is getting what it is spec'd for, but I cant find it anywhere. Appreciate any help with this issue!
