Thread: Break Out Board Install

I installed my break out board this weekend along with my 3 BAR map sensor. Big thanks to John for sending it out. The install was pretty straight forward, but I took some pictures to help out anyone else who was thinking about expanding the capabilities of the NEMU board's ADC inputs. It’s an awesome feature that makes data logging even more powerful.

Step 1) Install MAP Sensor, I made a bracket to mount it to a convenient spot on the intake plenum. I teed off the boost signal from the manifold.


Step 2) Connectorize the MAP sensor... I used a FAST brand sensor that came with a connector. There are three wires, Ground, +5V supply, and 0 to 5V output.



Step 3) Wire the breakout box. The terminals are labeled, so it’s pretty self-explanatory. The board has a voltage regulator that can supply 5 volts to sensors like the GM 3BAR (another great example of Nismotronic going the extra step) I hooked up the pressure signal into the ADC1 input. To utilize the 5V output line you will need to provide the breakout box with 12 volts.



Sep 4) Hook up the RJ45 cable to the NEMU board and breakout box. I buttoned up the break out box and used a few zip ties to strain relief the wires.




Step 5) Input the calibration constants in the software. They can be found in the ADC inputs tab in the "Settings window"

Thank you for sharing this!

This is a great example of one of the uses of the ADC inputs!

Nice write-up Dave!

Cheers,

So this would eliminate the factory MAF??

doesnt MAP need pressure and air temp?

As soon as John and I get the new versions of Nismotronic and TunerCode done, yes.

Cheers,
Dave

The way I have it written, the engine will run without an IAT sensor, however it may run rich or lean depending on the difference between the actual and default intake air temperatures (which can be changed). This is a timely question because I'm actually in the process of adding density correction, which compensates for actual IAT based on RPM and load.

Cheers,
Dave

In this example Dave F is adding the map sensor so he can log boost in the software and on the logs.

BUT this is exactly how you will set it up when you convert to speed density (remove the maf) with the new version!

does the ecu's support multi maps which can be switched by the driver?
I run an Exhaust cut out on my down pipe so when it's open the turbo reaches boost much sooner.

Yes, and here's a link to a list of features:
