![]() ![]() ![]() I installed a tune from Diablo, the Trinity said you may drive the vehicle now. When I re-married the trinity my PCM letters changed from "AE" to "AH". I followed the instructions and downloaded the latest CROM - v.1r13. Thereafter when I tried to re-marry the trinity it said it needs a calibration update. What happened to me is as follows: I was at the dealer and restored my original backup. I believe I have a similar problem as to the one described in the opening post. The car in question is 2012 Jeep Grand Cherokee 5.7 Hemi engine. I'm frustrated that a $600 piece of equipment doesn't work at all. It lets me successfully install the tunes but the Jeep doesn't run. I uninstalled everything on my computer, resinstalled all the drivers, usb stuff and did it all doesn't work. I tried this several times, including installing the 91 tune. It stated that the Performance 93 was in, and the vehicle was able to be driven. I plugged it back in, selected my vehicle, and successfully installed the 93 tune again. I unplugged the Trinity, and waited for about 30 seconds. I reinstalled the 93 tune again and it stated, Error, -18 reflash pcm locked.or something to that nature. I cleared the code, and reinstalled the back up factory tune. Forgive me for not writing the number down, but I didn't. There was a trouble code dealing with the TCM. I finally make it home, and checked the trouble codes. I barely made it back home, living in the mountains and 4th gear don't mix well. It would clunk and motor would bang on start up, the transmission would shift and bang, and it felt totally retarded(NO POWER) ultimately resulting in it going into Limp Mode (4th gear). It did the same thing, I just had to go to neutral to restart it. I took it down my driveway and out onto the highway. It would sputter and stall about every 30 to 45 seconds. Repeat the statement above about 10 more times. The drop slowed down around 800 rpm's and it sputtered. I started the Jeep, it showed idle at around 1300-1400, and steadily was dropping. It stated my vehicle was ready to drive, that the performance 93 tune was installed. I backed up my original stock tune and installed the 93 performance tune. It states that the version IS 1r13, and I selected my Jeep in the vehicle section. In addition to the extensive tuning support, it?s loaded with other features like the programmable shift lights, gauge display, virtual drag strip, and data logging.I just got the Trinity yesterday and uploaded 1r13 after installing all drivers and such on my computer.
