Setup with my Miata and a speeduino EFI, it's important to note that this product has no analog signal from the sensor, if you plan to connect this to the ECU, the signal comes from the Gauge. This would be cool, but my little miata didn't have enough power and the gauge was rebooting during crank. Added a voltage stabilizer to resolve that issue and its all good now.
