Mopar ECU questions...

[SoCal Rebell]

I just put my Mopar ECU in and I noticed a few things, the car idles MUCH lower, sometimes like 250 rpms, it doesn't stall but I am used to the 500 rpm level. Can this be adjusted mechanicly or by flashing the ECU? Also she runs a little hotter, which is no big deal now but when the temps get up in the 100s it may be a problem, again any fix? It is close to the 300 mile "learn" cycle, an answers or comments?

I usually idle around 400 with the ECU fully trained....I did notice running hotter in the city but she back down on the road...I have never stalled her once with the new ECU...dyno this week so I will let you know how my set up runs...

You can raise the idle by turninig the idle adjuster screw on each of the throttle bodies counter clock wise to increase idle speed. Turn only half a turn at a time. To drop temp change the fan module to the upgraded version.
Good luck, Dan Vargus/PartsRack.
