Hi

I have a problem with the coolant temperature input, it shows an incorrect value on my FC Turbo S5 1990 with adaptronic modular plug in ECU.
After I wanted to check the control unit input with the ohmmeter, I noticed that the pin for coolant temperature is PIN 3E in Eugene. In my Mazda repair instructions, however PIN 2E is designated as the coolant sensor input. 3E is crank angle sensor (Ne) on the OEM ECU.

Do I have to repin the coolant input to 3E of the Adaptronic ECU? What do I do with the signal crank angle?

Thanks for your help and sorry for my bad English

I'm not familiar with Adaptronic, but pin 3E is the coolant temp pin on the 1993-1995 RX7 ECU. I haven't checked all of the pins, but your first screenshot of the Eugene software looks like a diagram for a 1993-1995 FD RX7 to me.
