    interested in pass thru

    we are interested in purchasing pass thru for our shop. mainly our reasoning is for diesel trucks. we come across a lot that people have installed tuners in and have either bought truck from dealer so don't have original tuner or have lost it. we need to flash trucks back to stock before can load any custom tuning into them. question is have any of you ran into any be it ford, dodge, or chevy that pass thru or manufactures won't allow you to flash other than going back to dealer. would just like to keep trucks in house then farming them out. thanks in advance for help.

    Tuner PCMs likely been made FUBAR

    F'ed up beyond restoration .I think if the OE manufacturer's program can't see a bone stock PCM, then it will not allow one to write a stock calibration back over it.

      Tunners

      Most tunners i have ran across are the plug and play type . Fords use to be a chip that plugged into the back of the pcm and if you took the chip off you were back to the originl programms, the one dodge i did i just removed all the trash and that was it i did not have to reprogram. These were older vehicle so i am not sure if the newer ones are differnt. If you are looking to purchace a aftermarket programmer i have a new unit forsale it is the otc j 2534 programmer i could make a good deal on. let me know

          cool, appreciate the help guys. we pulled the trigger on it earlier this week. I had a 15 duramax come in but had my buddy come from the dealer to flash it back to stock. Got an 05 F250 waiting on new pcm to show up and will see how it goes. Truck was at body shop for 6 months killed 2 sets of batteries and jumped it numerous times and low voltage wiped out the pcm.
