I want my ECU to relearn.
There seems to be a lot of conjecture on this subject. Is there a once and for all way to start the learning process over on the ECU? I installed my neon injectors. Has anyone been able to reference something from chrysler??????

Disconnect pos. bat cable for 10 seconds, and touch it to neg. cable to drain capacitors memory. Reconnect pos. cable and drive for 10-15 miles so the ECM can relearn the parameters. That's what I was told by a dealer mech/tech.

ECU
1. Disconect the positive battery cable and touch it to a ground (the engine block) NOT to the negative post of the battery. for 30sec. this will discharge the PCM capacitors which has the adaptive memory.
2. Reconnect the battery cable
3. Turn ignition switch to the 'on' position but DO NOT start the engine.
4. Then turn the headlights "On"
5. Then turn the headlights "Off"
6. Then turn the Ingition key "Off"

idk. I am just regurgitating info that somebody had screamed at me before when I had posted that info another time. I don't think it maters but it can't hurt.
