What is done to modify a ECM ?
I have 55 lb injectors in my T. I have assumed (don't say it...), that I have a modified ECM, as anything above 50 Lbs injectors needs to be modified for the low impediance. I have also heard that some 55 Lb'ers do not require modifying the ECM.
I will be installing a powerlogger next week, and I was curious how to tell if it has been modified for sure.
Thanks all...
Mike
