No Wiper Blades Posted March 15, 2012 Share Posted March 15, 2012 I was wondering if anyone knew what PCM strategy changes there are with the Snow Plow option "on" or "off" in the PCM. I am sure that the cooling fan would be on more at higher road speed but beyond that I am not sure. Trans shift a little late perhaps? Any thoughts would be more than welcome.

Cetane Posted March 15, 2012 Share Posted March 15, 2012 I cant speak for the trans but the only change in the ECU is in the fan subsystem. Quote Link to comment Share on other sites More sharing options...
Aaron Posted April 7, 2012 Share Posted April 7, 2012 Does the PCM change for the fan substitute for the different clutch on the older 6.4/6.0 trucks that had the different clutch? or does the 6.7 have a different clutch also? been out of the ford world for awhile, so haven't been keeping up with em.
