I noticed in the I-Command User's Guide that the I-Command will winterize only 115 HP to 300 HP E-TECs. Just curious why it won't winterize the 75 and 90 E-TEC?
The EMM on the V4/V6 models is larger, and has the capacity for the driver circuits and memory/programming requirements.
Hope this helps.
Thaanks John. I was going to eliminate my "System Check" Tach, but now it will be staying. Thanks for your help.
