Vi-PEC ECUs
Compatible with ViPEC V44, V88, i-series and Link G4,G4+ ECUs
The ECU with firmware version 4.2.0 onwards must be set up to output the required data at 57.6 kbaud, the DataStream mode also needs to be set to "off". After these settings have been configured turn the power off the ECU and back on again. Changes to baud rate and DataStream only take effect if this is done.
You will also need a cable from the ECU manufacturer in order to connect the Race Technology interface to the data output of the ECU.
