My main question is about, first off how to do it.. Also I run the Flashpaq on 87/93 tune... And was wondering if I reset the ECU, would I have to reset my tune on the Flashpaq??? Also another question, I was at a red light today and all of a sudden the jeep idled real low, like at 500rpm when I was just sitting at the light.. Any thoughts as what could have caused that?

 

Not going to be too much help so at least a free bump ...

On the previous cars that I've owned to reset the ECU you just disconnected the battery, stepped on the brake for awhile to discharge any capacitors in the vehicle and then put it back together, ECU was then reset and you could drive it like you stole it to recondition the factory ECU to perform a wee bit quicker

 

The FlashPaq should allow you to put it back to stock tune. You can then disconnect the battery for a bit (say 1/2 hour) to reset all sensors.

 

Oh okay, but its best to redo the tune after you reset the ECU?
