I am trying to figure out how to input my 0-5v reading from my 2002 miata fuel level into my MS3 Basic. I have the divider circuit working fine, I just cannot figure out how to map the input to one of the DB37 pins. There is a pin labeled "SPARE_ADC Analog Input" on pin 12 that seems like the logical pin to use, but I cannot figure out which input pin 12 maps to in the add channel wizard. Any ideas?

The MS3 pin list is on page 4 of this doc: https://trackspeedengineering.com/fi...20V3%20140.pdf

 

I'm guessing it's generic sensor input 1 or generic sensor input 2 (that's what the explict "spare 0-5V" analog inputs are on the MS3 Pro).

 

Hi

On my MS3 Basic it maps through to SPARE_ADC (ADC13)...

Cheers

Ahh - just had a look at TunerStudio and I think I see what you are trying to do...

Advanced Engine -> Generic Sensor inputs.

Pick a free sensor source, then select SPARE_ADC as the input. Give it a friendly name if you want

Then in Add Channel Wizard, select the input you just bound to SPARE_ADC as your source (eg. Sensor 01).

I'm not sure if you need to do your 0-5v mapping in the Generic Sensor Input section to define how the input is scaled, in the Add Channel Wizard (which may just define how the gauge is scaled) or both!
