Tucked between the valve cover and fuel rail, the front bank sensor harness has the DBW throttle connector (with the red tab), three oil pressure sensors, and an oil temperature sensor. On the rear bank, there is the Motec LTC (Lambda To CAN) module, ECU Master EGT to CAN, EMAP, and other sensors.
The factory (green) VTEC pressure sensor was no longer needed.
We replaced the VTEC sensor with a line running to new pressure sensor.
This RaceGrade oil pressure sensor will allow the Motec M150 ECU to log the pressure fluctuations of the VTEC system on track.
We originally monitored oil temperature and pressure at the oil filter housing via an archaic HKS CAMP 2 system that displayed the values on our double-din head unit. Needless to say, there was no way of data logging these channels or to monitor them properly.
With our Motec M150 ECU and sensor harness, we are now logging countless channels to evaluate the upgrades and modifications that we are making to the C30/32 platform.

I forgot about this project! 9000+ rpm from an NSX is going to sound sweet.
Give us an update on Project Viper, too 😉
i’m interested in why you chose to run stock fuel lines/ filter but upgraded your pump for e85?
The upgraded fuel pump has not been installed yet (and has been changed since the original fuel pump article). An updated article on the new fuel pump and upgrading the whole fuel system from the lines to the filter, injectors, and rails will be featured in an upcoming article. Stay tuned!
