Diablosport Forums

I just got a used over the weekend and thought diablo was similar to Superchips and SCT with backing up the PCM before doing any modifications to the computer. I started the process to load the tune after making sure I had all the updates necessary. Well I received a TCM error during the process and now my PCM is wiped. My truck is dead and it is sitting there. I have contacted support....

My reason for this is to try to avoid this for other people, because crap like this sucks and luckily I have three vehicles and I am not at a total loss, but my truck is dead until I can pay to have the PCM reflashed . So I am really feel for the people that have gone through this and it is their main vehicle.

My main question is there a way that a factory file can be manually saved before Diablo does anything with the PCM?

It always saves the stock tunes first...

Ok. Is there anyway to do a manual save just to be on the safe side?

I tried researching this but could not find anything on it. Are you able to do a manual forced backup of the PCM before doing anything to the truck? I know you said it automatically does it but what if it fails to do it properly like in my case when it tried updating the calibration on the truck.

you cant take a backup before you load a cal update, no.
