2024 LZ0 ECM CALIBRATION UPDATE

Hit my first regen at 400 miles during a 12 mile trip, as best as I can tell without a Banks idash gauge. No dash lights.
 
Still no call back from OnStar but as of this afternoon the app is updating correctly and the emissions fault is gone. No CEL's since the ECM update. Another post TSB benefit is that I've seen a healthy increase in the miles driven between regens. I do a lot of short distance driving. My average distance between regens pre TSB was 165, post TSB I'm averaging 185, and hit 190 on the last regen.
