Canems ECU
Compatibility
- Only available on units 1308 or later
Configuration
- ECU configuration not required.
Connections
- ECU has a standard male 9 way d-type
- The Race Technology ECU Serial Interface uses the same connector & pinouts, so a null modem cable is required to connect the devices together.
- A Null modem cable switches pins 2 and 3 with female connectors on both ends (Null modem supplied with ECU Serial Interface).
Data Channel listings
- Some values may be 10 times larger than expected, depending on the model & year of vehicle. If this is the case, simply divide value in the Analysis of configuration software by 10 to get correct value.
- 1 ADC (analogue input) count is scaled to 1mV by default.
