I attempted to unlock early 2000 gm truck ecu's and instead of 6 credits for all 99-07 it charged me 5 credits. Flashed an 02 ecu then I was attempting to flash an 01 and it wouldn't let me. I'm just attempting to see if anyone may have an idea of what happened. I have purchased over 60 credits flashing ecus and figured I should just unlock all of that era.
6 credits doesn't unlock all 99-07's, it would only unlock one entire year. So for example the 6 credits would unlock that model year 2002. It does or did cost 130 credits to unlock all 99-07 trucks.
You likely got "credit" for that specific model year you unlocked because you previous tuned a 2002 computer, that's why it only cost you 5 credits and not 6.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
Well that explains a lot and I wish that were more clear on the vehicle list were it shows 6 credits unlock 99-07. Fine print I guess.
