Ok, many Thanks

Thanks renns

...based on the file menu...selecting RX-7 defaults....the Bias resistor for the ECT is the same value as the GM defaults

but the IAT value for the Bias resistor...changed from 2490ohm to 47000ohm

Do I need to change the resistor R4 in the PCB(IAT) from 2.49K to 47K?

Thanks

Does anyone here have tried using the factory Mazda IAT and ECT sensors? What are its resistance curve values that I need to enter with Easytherm?

Im using MS1 V2.2...no extra code yet

Particularly the Mazda BP(1800cc DOHC 16-valve) and the Z5(1500cc DOHC 16-valve) from the Mazda 323/Protege ...
