Climate Control And Aftermarket Ecu's

[GTRNUR]

Hi All,

Ran a diagnostic on my climate control today and discovered there is a water temp input signal from the engines water temp sensor. It appears that the water temp signal is shared with the temp signal from the 2 wire temp sensor on the engine.

When I wired in my Wolf ecu i neglected to wire this signal back to the climate control, so the climate control had no idea what the engine temp was, and as a result can't mix hot and cold air properly.

So... how does everyone get around this?

I tried wiring the signal back to the temp sensor again, bit this affects the temperature that the ECU see's as the climate control's input impedance drags the signal voltage down.

The only other thing I was thinking of doing was fooling the signal input with a variable resistor so I could fool the climate control ecu into thinking the engine is at 80 degrees.

Anyone have any thoughts on this?

Cheers,

Ian
