The NGC3 controller is a separate PCM and TCM. But when you do a read it creates a single HPT file.
When you do a write the PCM and TCM are listed separately and the PCM has a Write Calibration option while the TCM only has a Write Entire option.
If I make changes to the trans tables, do I need to do a TCM full write or will a PCM Write Calibration do the job?
