02 lighning ECM changeout
Two questions for anyone who has changed out the Eletronic Control Module on a lightning (02)
1. When installing a "new" module the manual calls for the throttle position switch (TPS) to be re-calibrated via the Harley Scanalyzer. An expensive item that I do not own. If installing the new unit how far off will the zeroed (idle) position be off? Will the full throttle positon also be out?
2. If finding that the "new" module does infact need calibration can I reinstall the original? Does it keep the already known settings? My belief with other types of systems the answer should be yes, but I'm not sure. If a battery were changed out one would hope I do not require a re-cal of the ECM each time!
Thnx in advance for information! RDS
