Bluetooth Dropouts (MPVI3): Some users report intermittent disconnections when logging wirelessly with high-channel count layouts (more than 24 channels).
Cobalt Write Failures: A minority of users tuning older GM Cobalt SS/LNF ECUs have reported "Write Calibration" failures requiring a full recovery flash.
Lambda Conversion Errors: In VCM Scanner, a bug affects the conversion from Lambda to AFR for certain alcohol sensors; you must manually set the stoichiometric ratio.

7. Recommendations for Users

Upgrade Requirement: Users with MPVI2+ or MPVI3 hardware are strongly recommended to update to at least v4.12.4 if tuning late-model GM trucks (2020+) or Dodge Chargers/Challengers (2021+).
MPVI1 Users: Do not update. V4.x does not support legacy hardware. Continue using the last stable v3.x release.
Windows Users: Ensure the HP Tuners device drivers are installed with administrative privileges before plugging in the device to prevent driver conflicts.
