M800 with Denso IAT sensor

[SuperNutz]

Is it posible to use Denso iat and water temp sensor? if i have the sensor resistance value ?
Any one know Motec internal resistor for iat and water temp value?

Thanks

There are Macro's for the delco sensors in Adjust>Sensor setup>Input setup.

You will need to use a custom calibration for a denso sensor. Do you have resistance vs temperature values for the sensor?

The M800 AT inputs have 1000 ohm pull up to 5V and 100K ohm pull down to 0V.

Thank Ross
i have calibrate resistance vs temp. pull up resistor values is all i need for voltage curve

Taking the 100k pull-down in account in your calculations is important at low temps, lower than 0°. Else, it will not make a significant difference.

I doubt it would be anywhere near 0 degree where i live, but thank for the info
