ECUType / CanemsECU


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
    • 2 Rx
    • 3 Tx
    • 5 Gnd
  • 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.
