VEMS V3
ECU configuration
No ECU configuration required.
Connections
- ECU EC18 pin15 is Tx
- ECU EC18 pin14 is Rx
The ECU has standard wiring to the DSUB9 connector, which allows our ECU Interface to be plugged in directly i.e. 'ECU' labelled connector connects directly into the DSUB9 connector built into the ECU casing.
Alternatively connections can be made via a null modem cable with two male DSUB9 connectors, this would be used only when the 'built in ECU Interface' license has been purchased with your Race Technology product.
