Ok so I did a dumb thing. I was switching over from Diablosport to HPtuner. I bought a used 2016 PCM off eBay. Set my Diablosport PCM back to stock with my i3. Read the tune with the HPtuner MPVI3, then put my tune back in. I am MDS delete so I have to run the tune to turn it off and not get CEL. Also running the MMX no tune required cam with my MDS delete. Plan was to get a Flyin Ryan tune. So, on to the dumb thing I did. I was flashing the Diablosport back to stock, and thought, while that flashes I’ll unbolt the PCM so I can swap it once it’s done. Well, I couldn’t get the wrench on the lower bolt and without thinking disconnected the one connector on the PCM while it was returning to stock. Soon as I did it I realized it but it was too late. i3 said it had restored the backup, but when I turned key to start truck nothing happens. So, I obviously bricked it. That being said, what are my options with it? Can I unbrick it? Take it to dealer to reflash stock then retune with my i3? I installed the HPtuner one and it takes a while to start, barely runs, idles rough, and throws tons of codes I assume because I don’t have a tune for it and the non MDS cam is an issue. I have talked to Flyin Ryan about getting a tune but I’m without a truck at the moment. I’m hoping they can get me a tune to get me up and running, but I’m concerned it’s going to need to be custom tuned. FRP informed me the cam I got really doesn’t work as well with stock PCM as advertised and I would need probably need custom tuning. I tried to read the Diablosport tune with the HPtuner, hoping I could load that after the PCM swap but it didn’t work, still runs rough. I get all kinds of cam codes, misfire codes, throttle position codes, and takes forever to turn over, plus it smells like gas.
So, I’m an idiot and created this problem because I couldn’t leave well enough alone, but any help would be appreciated….
