Hi there all,
Been on here for years and haven't posted much, if any, but I am in need of some help from you guys today. I have a 5.2XS crate motor with a FRPP Controls Pack and I cannot for the life of me get it to idle well, if at all, once the fans come on. Cold start good? check, Hot start good? check, WOT good? check.
I got everything out of the way and then noticed the idle was really surging with the A/F ratio wigging out so after going through all the throttle body settings (IPC error was all over) and whatnot I got it to idle like stock, drive like stock and making what I would consider the correct HP & TQ (490 RWHP and 380 RWTQ on a 94-degree NE day so I think the power seems good) but the minute the fan comes on it all goes to hell. I have read post after post and found guys with the identical issue and did what was recommend tried changing the ETC Predicted, Driver Demand Table, Torque & Inverse Tables, Idle Torque Proportional & Gain tables plus a ton of other changes but I am out of theories and ideas. Any feedback and opinions would be greatly appreciated. Thanks, Chris
