To power the PMU-16, we ran a 2AWG cable from the fuse box (which we relocated to the left of this diagonal chassis brace), into the cabin and to the PMU-16. The PMU-16 stud also has a 6 AWG cable that powers our amplifier, allowing us to remove the 10 feet of battery cable that was previously routed though the car.
To take full advantage of all of the channels of the PMU-16, we ran powered lines to the front of the car, through the front bulkhead.
From the front bulkhead, we have the PMU-16 power a ton of devices.
On top of the original fan is this wide and skinny resistor to change the speed of the fan.
Now that we are powering the fan directly from the PMU-16 by bridging two 25amp (continuous) outputs, we are able to remove the factory resistor and no longer need the original connector.
In addition, the PMU-16 powers the water pump for the air-to-water intercooler, the air pump for the front lift system that we are designing,
Overall, the ECU Master PMU-16 is an incredibly versatile device that we were able to install cleanly in our NSX and utilize many of its features and datalogging in the rest of our electrical system. We are excited to start incorporating many of these aspects as our NSX gets closer and closer to becoming the refined, turbocharged monster that we have planned for it.
Stay tuned for future updates!
