suddste Posted July 14, 2017 Share Posted July 14, 2017 Hello, Ford updated the PCM to the latest calibration on my car, this does not work well with the remap. I was wondering before I ask Ford, if the PCM update can be put back to the original? I was told it could not be. Thanks, suddste Quote Link to comment Share on other sites More sharing options...
iantt Posted July 14, 2017 Share Posted July 14, 2017 Any remap will have been written over by the pcm update. And it's not possible for ford dealer to revert to earlier state.who was remap done by? Quote Link to comment Share on other sites More sharing options...

JW1982 Posted July 15, 2017 Share Posted July 15, 2017 If you know the exact software version that was on the PCM before the update it will be no problem to downgrade to that version. Every Ford dealer can do this by using some tricks during the (non com) update procedure. However to do this you need to know the exact software version number. 1 Quote Link to comment Share on other sites More sharing options...

JW1982 Posted July 15, 2017 Share Posted July 15, 2017 I used this method many times without any problems. However or should not be needed to downgrade the software. The Superchips remap should overwrite the original software completely. Quote Link to comment Share on other sites More sharing options...
suddste Posted July 15, 2017 Author Share Posted July 15, 2017 I have the original strategy number: F1F1-14C204-JF How would I go about telling them it could be done? Quote Link to comment Share on other sites More sharing options...
