Guys I have an 08 6.4 at my shop that I can't get to take tune. Can't get it figured out and wanting to see if anyone on here might have a suggestion. So here's the story on it.
Pulled truck in shop did egr delete and dpf delete. Truck had a superchip on it at the time. Went to remove SC and it gave error while uninstalling. Battery too low. Hooked up charger and got SC off truck. Went to load an SCT X-4 with custom tunes to truck. X-4 kept freezing whole saving stock file. Put battery charger on truck, still same thing. Ended up putting brand new batteries on truck with charger hooked up. Still nothing. Well during all this freezing failed loading ended up bricking the PCM. Sent it off along with TCM and x-4 to the tuner for repair. While that was out we grabbed a PCM and TCM off a different truck. Flashed it to this one with our IDS. Started trying to load a tune on it using a different SCT. Still froze while saving stock file. So thought something wrong with the X-4. Grabbed an H&S off self and tryed it. H&S will get part way though loading trans tune and freeze. Took two days to get the H&S back out of recovery mode and off truck. Fast FWD a few days and we get the original PCM TCM back from tuner. Tuner said they were able to bench flash it no problems. So we load it to the truck. Use the IDS to setup everything again. Tryed X-4 still same thing. Tryed H&S still same thing. Now truck is back to tune stuck in it from H&S and H&S stuck in recovery mode since it only got to 33% loaded on trans file before just freezing up. I don't know what is going on with it.
So quick recap - truck won't take trans files - tryed 2 different PCM and TCM - tryed 2 different SCT and a Mini Max - tuner was able to bench flash PCM and TCM no problem - 2 brand new batteries and a charger hooked up still no help.
Sorry for the long post but wanted to get as much info in as I could. Hope it makes since and someone here can help out.
