ok so I tuned my friends truck about 2 years ago never had a issue and he had his batteries die up in nd after getting new ones he said the truck wasn't running the same and had lop and his cts made him manually enter his vin before it would work which was odd so I told him bring it by I wanted to reflash it.
well when I went to flash it it said I needed a vin license which I have already licensed the truck. I was like wtf I read his truck and the vin was just symbols and dashes his calibration number was 33886413 which ive never seen before and the bcc was just dashes and ?? marks I had a screen shot but..... my laptop died charger wasn't plugged in like I thought but anyone ran into I tried flashing his old tune in with a new vin license still didn't take a vin told him to try a full flash from gm otherwise probably a new ecm??
security light is also on the dash im sure from not having a vin the truck also loops because its pulling mm to 1-0 non stop trying to kill it at idle it seems
