If your battery voltage dropped in the middle of a write, you most likely bricked your PCM and will need to contact Diablo. May need to send them the PCM as well. I cannot stress enough to always connect a battery charger when loading a tune. There are many modules that are turned on when it goes through its process.
The only thing you can try at this point before you pull the PCM and send it off is to charge the battery, leave the charger on and try to restore the stock tune. The folks at DiabloSport can walk you through a "Force Load" process but if it doesn't work, then the car won't run until the stock tune is restored. DiabloSport has restored other peoples cars before so all is not lost. This work is much less than reflashing your PCM or replacing it at the dealer.
If they get it to work they might be able to restore the trinity during the process. However, if they can't restore it over the phone or through email (they may have something they can send you to load on the unit) you'll have to send it in. I have no idea what they charge for that these days.
You don't have to restore the stock tune every time you install a tune. If that were the case, my car would be screwed as I've written 7 different tunes to my car and have not restored the stock tune once.
What did Johan do with that tune? Must be different than the canned tunes because if you try to load a 93 modified (within mods allowed by the tool) on top of a 91 canned you'll brick the PCM.
Oh well, things may have changed since I almost bricked mine oh so long ago! at:
I call them they need me to send the lcm for them to get it reflash but they say they won't charge me nothing. Just for shipping and handling. .but when im fiing out the form it says i have to pay 100 dollars? ? I might have to just get it done here at a dealer they charge me 120..
Connect a battery charger before writing any tunes to the car, especially if doing multiple writes (going back to stock and then writing another tune). Multiple writes will kill a battery fast.
Nothing to be afraid of.
