Post RaceCapture/Pro MK3 in a 1999 Miata 
Hi all,

Can someone double check a wiring diagram I came up with for our car? As a first stage, we want to get this basic data:

Sensors:
    Fuel level
    Oil pressure
    Oil temp


OBDII:
    RPM
    Engine temp
    MAF


RCP:
    GPS
    Speed

Hi,

What temperature and pressure sensors are you using? Do you have the calibration information? This would be a chart showing the resistance value of the sensor across a temperature or pressure range.

Without this, you would be able to hand calibrate by taking resistance readings across temperature or pressure - tedious but possible to do.

The 1/4 watt 220 ohm resistor is fine for the 5v reference; the 180 ohm you should do 1/2 watt. You can safely use 1/2 watt for both.
