After market gauges need to be used with the sender that came with them or is specified for them. They are not interchangable with even US OEM sensors. Not only are the calibrations differenet but some even use sensors that wor in oppositie directions. For example, the ECU sensor you are using is a reverse device with resistance that decreases as temparature increases. many after market gauges, are reversed.
