GMPP engine controller a/c request pin? I have a GMPP engine control with harness part# 19244807. Does anyone know if these systems are setup to receive an a/c request signal to bump up the idle? I can't find anything on the manual and a call to my gmpp dealer did no help.

If you find someone with EFIlive, tell them to add some more air to table B1829 in the areas under your actual rpm idle speed. Then if it drops a little, the airflow will add more in. That or if they have time to be more exact, tell them to modify tables ,B1843 and B1845 proportional idle correction based on rpm error. That WILL fix your issue.
