I am wondering if anybody can help...
As you know I have fitted a Mazda MX5 engine and box to my Firenza but I know have an issue with temperature gauge of sorts. The gauge reads fine but it says its too hot, which would be true if the temperature was this hot with the original 1256 engine, however MX5's run a lot hotter with 87-93 Celsius being the optimum temperature.
What I am asking is if anybody knows how to get the target temperature of 87-93 to sit in the middle of the gauge, so that when it goes hotter than this it moves to hot?
It might not be possible but I was hoping not to have any extra gauges unless I really have to have any.
Car is currently using a 3 wire temperature sender from the MX5 with two wires going to the ECU which gives me a digital output on the laptop and the third wire goes to the gauge.
