Just received the notice from Chrysler for the Emissions Recall L34-Reprogram PCM....since I am running a Superchips Fashpac program, (tow tune) on my 2010 Rubicon, It is my understanding that I must reset the program to the "stock tune" before taking it in for this reprogramming to avoid any problems with my Superchips programmer???? does it have to be run in the "stock tune" for any given length of time before taking it in???? any advice concerning this is appreciated.

 

No. Reset to stock and good to go.

 

No worries, just did this last week. Reset to stock, they did the recall, and I reprogrammed with the superchips before I even left the lot. No issues!

 

On a slightly different note, AEV ProCal users don't have to do anything. All my changes were still there after the recall.
