Here's a quick history. 9 Months ago a friend was selling his tuner after trading his truck in. We installed it into my (at the time) stock Avalanche with no problems, and I put the '93 Octane' tune in.
Fast forward a few months to now. I've since lifted the truck, put mega strobes in, a Fosgate system inside with 2000+ watts hitting it. Remote start. Train horns. Front & Rear backup cameras and a few other goodies.
Anyways, a couple of weeks ago I wanted to put my stock tune back in so that I could make a trip to the dealership. I plugged in, as I always have, and got this:
I tried multiple things... (after reading similar issues).... My battery pack (for extra voltage), my battery chargers, killing the power to the amps & head unit. Shutting the heat/ac, DRL's and anything else off.. But nothing. No matter what I do, I get the same message. I have not physically pulled any fuses (amps/head unit has trippable power blocks under the hood).
I'm at wits end.. Can any of you guys offer any assistance?? I bought the power supply for my U7193 the other day to update the unit, but that won't work because I have the factory tune inside.. .
Thanks in advance for any help you can offer!!!
