¶ Initial support in v1.0.131
CAN-communications based on the John Reed Racing package.
¶ Features
- Torque estimation from the ECU
- Cuts and blips 0/1 triggers through CAN
¶ Connection
CANTCU CAN3 is connected to MoTeC.
- CAN Speed is configurable
- CAN2.0B, Standard 11bit identifiers
- All 16 bit values are Little Endian
¶ Integration
¶ MoTeC Configuration
- JRR CAN setup
- Torque needs to be calculated in MoTeC (corrected & uncorrected)
