If your car has CAN BUS that broadcasts Engine RPM all you need is USB CAN interface (ORP unfortunately does not have USB connection) which costs extra 80 EUR. If gear (or gear position) is not visible on can bus, you need to hook up gear voltage to the ORP gear voltage input. With free software that comes with ORP you need to configure gear ratios and maximum RPM and you're all set.
If your car does not have CAN BUS you will need:
- External device that will read the rpm and/or gear and send it to CAN BUS
- Or configure your ECU that will activate AUX output based on your conditions (rpm/gear table)
- Or use MME Motorsport GCU8 that will be able to control this + A LOT MORE. GCU8 Lite price is 450 eur and can do flatshift and throttle blip. GCU comes with USB connection so no other component is needed.
