Project NSX: Part 21 – Foundry 3 K-Coil Swap

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.
