So I'm thinking about trying to send in a sensor voltage to the pin on the copperhead ecu that's used for fuel pressure on the GT500s on my coyote car.

Does anyone know the range of the GT500 sensor? 0-100, 0-150psi etc.

Once the switch is on I'm hoping hptuners will recognize the PID as it does with flex fuel but we will see. Hopefully this is something HPtuners can implement if it doesn't.
