Hello Everyone,
I need to share the throttle position sensor signal going to the engine ECU with a central differential controller. If I connect both controllers to the TPS (throttle position sensor) the engine ECU reads as it should until I start the engine. Then the TPS value changes by about 1% to 2%.
I have made up this circuit that sort of works. The problem is the voltage into the diff controller is not exactly the same across the 0 to 5 volt signal range of the TPS.
