Link G4+ and LINK G4X CAN
Compatibility
These instructions are compatible with the following models of ECU.
Following information relates to Link G4+ firmware version 5.1.0 and later.
ECU Configuration
In order for Race Technology products to communicate via CAN to the Link ECU some CAN setup is required on the PCLink Software. To do this go to ECU Controls > CAN Setup
Depending on which LINK ECU you are running you maybe able to configure 1, 2 or both CAN buses. Refer to connections section on which option (1,2 or both) the ECU supports and which one is best for you and select the following settings.
Using the screen below, set up the CAN to the “User Defined” mode at a bit rate of 1Mbit/s.
- Select “Channel 1” and using the Mode drop down list select “Transmit DASH2PRO”.
- Set the Transmit Rate to 20Hz
- Set the CAN ID to 1000
Click apply and then select OK. This will take you back into the main map screen. Apply the changes to the ECU and save the file as a revised copy on the Computer.
Connections
- Connect Race Technology CAN+ to LINK CAN+
- Connect Race Technology CAN- to LINK CAN-
