¶ Initial support in v1.1
¶ Features
- Engine Parameters relayed to CANTCU via CAN-bus
- Freely definable ID for the CAN-communication
- Cut requests to M84 through CANTCU Digital Outputs
¶ Connection
CANTCU CAN3 is connected to CAN on Motec M84.
CAN Speed user-definable (default 1Mbps)
¶ Torque Factor (CANTCU)
To achieve a somewhat realistic torque estimation, we use a Torque Factor. The torque factor is generated from engine running values taken from a single point of running (usually maximum measured torque on a dyno run). The values needed for calculation are listed below.
- Maximum Engine Torque (Nm)
- Manifold Absolute Pressure, MAP (kPa)
- Max. Efficiency %, Fuel Table
Entering these values in the calculation window will generate a torque factor, which will be used as a baseline for torque calculations in the CANTCU.
¶ Integration
NOTE!
All tuning should always be done by a professional in safe environment (track/dyno)
Before activating the blip function, it’s recommended to test downshifting and verify (realtime or logging) that the user table is behaving correctly during the blip. Starting values for tuning the blip should be low and gradually increased to avoid overrevving and undesired behavior/acceleration during the shift.
¶ M84 Configuration
The CAN-communication from M84 to CANTCU uses the "Dash/Logger" feature in MoTeC M84 CAN Setup. The default broadcast address is 232 (= 0xE8 hex).
¶ CANTCU Configuration
- Motec M84 Protocol needs to be selected in ECU configuration.
- ECU Receive ID needs to have the same CAN ID as defined to be sent out from the M84. Default E8 (= 232 decimal)
- Digital Outputs can be freely assigned to trigger on cuts (grounding type). If blips are somehow available on the ECU, you can also optionally define a digital trigger out for the blips.
- Wheelspeed values are not automatically read through the ECU integration, so wheelspeed simulation needs to be enabled unless you define them manually on CAN Inputs.
