The throttle cable (left) is a bit of an eyesore and out of place on our otherwise clean engine bay. For our Drive-By-Wire (DBW) conversion, removing it (right) was one of our first steps.
The throttle cable was removed from the rear bulkhead and left this hole. We used a rubber grommet to plug it and then drilled a hole just above it to fit our bulkhead connector.
The OEM Fuel Pump Resistor (left) was no longer needed since our ECU Master PMU-16 now controls the fuel pump directly. We were able to remove it (right) and can now see the new autosport engine wiring harness bulkhead connector to the right of it.
The mil-spec engine sensor harness is responsible for everything from a new crank position sensor, fuel pressure, multiple oil pressures, flex fuel sensor, multiple temperature sensors, MAP/MAT sensor pressure, turbo speed sensor, and more.
We will be using an ECU Master 8 Channel EGT to CAN module to measure our exhaust gas temperatures as well as other temperatures using thermocouples.
We are using a dual-channel Motec Lambda to CAN (LTC) sensor with 02 sensors on each bank of our V6 engine.

Another Billy cutting-edge NSX project! DBW opens up tons of interesting control possibilities!
The mid to late 90s in between/early years of DBW had so many weird contraptions. I would love to hear about why certain decisions were made for so many parts on cars!
i was thinking the same thing as he was going over the new DBW pedal.
Excited to see this paired with the ECU Master PMU16! Modern brushless fans and pumps are awesome, both in low power consumption and control capabilities. Let me know if you want another set of eyes on your turbo plans.
