Known Limitations

• DMA PIDs may lose valid data if ignition is switched off during an active data log session — restart the log after ignition cycles
• CMF (CM2450B) Cummins 2022 tune files will show an OS warning — this is expected; stock files can be opened and flashed, modified files cannot

Note: Do not attempt to flash modified CM2450B files — the vehicle will be left in a no-start condition until a stock file is reflashed.
