Electromotive TEC GT
Compatibility
Configuration
This ECU should be connected via CAN connections. The CAN bus must be enabled in the ECU mapping software. All TEC GT ECUs sold since around 2005 are compatible with the following CAN setup:
Connections
Electromotive sells a Y adapter, this cable splits the CAN & RS232 connections from the ECU connector. If the Y adapter cable is not available, the following connections are present on the ECU connector:
Pin 1 is CAN high
Pin 4 is CAN low
Neither their end nor ours is terminated, and there are no other nodes, so two 120 Ohm resistors are required, even if the intervening length is very short.+'
