Data from EMU ecu over can bus?

Postby Ole » Tue Oct 07, 2025 9:18 pm

Hi,

I am planning to get an UTCOMP Pro since it is a nice replacement for an Opel Astra F MID (matching colour, good size).
For the beginning I can get oil temp, water temp, pressure, ... from the original/existing sensors.
For next year it is planned to switch over to an EMU BLACK ecu. Then I will also have AFR and EGT within the ecu. Is it possible to send this data over can bus to the UTCOMP PRO? Or what would be a good solution? I would love to have communcation over bus, so less cables are needed. The complete motor loom will be made new.

Best regards
Ole

Hi Ole,

CAN-BUS is not supported, for EGT you will need to get amplifier output (e.g. EGT-K OUT connected to UTCOMP + EMU at the same time) and from AFR the same situation - AFR output from controller connected to EMU and to UTCOMP.

RCOMP has CAN-BUS but only for basic OBD2 data (speed, rpm, boost etc.) and it does not have dedicated oled display at the moment.
