How to M73 V12 on Proteus¶
- 💲rusEFI Proteus💲 can run a M70/M73 port-injected v12.
- We do not support unusual M73 throttle bodies; we also only support 6 wire pedal position sensors. Nissan throttle bodies are the best fit we have found for M73
- MAP sensor fuel control strategy is recommended; that would require MAP sensor to be fitted on the engine

The Nissan Hitachi SERA576-01 60mm throttle body is recommended. In order to mount the SERA576-01 you just need to drill ETB bolt passages to 10mm / 3/8".
About six wires are different between Proteus 0.2 and Proteus 0.3+ - all on the 23-pin plug.
This HOWTO focuses on M73 engine with a stock ECU harness. The 1998 stock ECU harness has two 134-pin connectors.
The 1998 example used as a test mule has a black connector and a grey connector. Each connector has 9+24+52+40+9=134 pins total.
rusEFI uses six wire colors: black white red orange green blue.
Proteus¶
- +12V from main relay
- 12 injectors
- CLT
- IAT
Total wires between Proteus and the grey connector: 10 Total wires between Proteus and the black connector: 22
Destination legend: "Black #3 40/52" means "Black set of ECU plugs, connector #3 - pin 40 of 52 total pins"

Pictured is a Proteus with ampseal connectors, non-BMW pedal sensor, two non-BMW ETB connectors, ignitor, and two breakout boards for the stock connectors.
The OEM pedal and ETBs are too unusual, thus a complete redesign of pedal and ETB hardware and wiring was expedient.
