I put the car in accessory mode plugged in the tuner module and it read out the same serial number as on the back of the tuner device. It showed me a DTC # U300A. It didn't say what it was but shows to have cleared it. Any idea what that code is ?
It wanted to go into tuning mode I pressed the start button as prompted and got the error message "59" "no tune detected contact the tuner" or something like that.
I never saw an option to get to vehicle info, or strategy code / VIN number or anything.
This is for my 2013 SHO with performance package I'm terrified to erase or screw up the ECU. I don't feel real good about the instructions it came with too vague and basic and not what I'm really seeing while trying to operate the Excalibr8tor. I'm excited about loading a stage 4 tune though but feeling very paranoid about messing up the computer with the tuner.
