so when i got home from work i did like one of the other members suggested and blipped the key a couple of times and it did clear all the chaos on the dash and i was able to flash in a tune that had VATS enabled, but the 2 skim switches off. Also for good measure i pulled the remote start module AND yanked the keyfob simulator out of the steering column.
All appeared well. I drove it around all day and even managed to upgrade to the CSP5 and had been test driving, tuning, and reflashing as i went with no problems.
UNTIL halfway through a flash, the dash lit up as before and got an 0549 code.
Now it appears completely piled up. none of the tricks to let me communicate with the ecm that have worked up til now will work
