CANTCU integration with MaxxECU.
How to make it work
1. Select MaxxECU as the Car/ECU Protocol and click the setup button, available in CANTCU v1.0.134 or higher.
2. In setup (CAN3 configuration), set the correct CAN speed and offset (if used).
3. Enable the CANTCU protocol on the MaxxECU side, MTune.
No need to setup custom CAN messages for blip, shiftcut, just activate and setup.
In MTune 1.151 the we added the option to set the VSS SPEED from other source, so the above speed source must be selected for VSS SPEED to come from the external TCU control protocol.
