I am looking for a data sheet for my TMAP sensor bosch part number "0281002845". The sensor looks identical to the one on the Motec calibration chart.
Markings on rear of sensor are same as pictured also, just doesn't show the Bosch part number.
My question is, does anyone know if this is the correct calibration chart?
One other question I have is I should be able to use 2 of these and splice the supply voltage and ground for 2 sensors but IAT temp signal wired to a separate sensor of the same type so I get a more accurate measure of the intake air temp and not have to deal with potential heat soak of the throttle body?
Thanks, still new to this all.
This part is on the Ballenger website, they show the calibration electrical and mechanical data. That part is also in the pull-down menu option for Temp and Pressure Sensors with MoTeC M1 Tune.

Since the IAT portion is just a thermoresistive, you only need to use signal and ground for that, normally you would connect that to a temperature input with a built-in pull-up resistor.
Thanks! I've checked the slope and offset from what I had and they are the same sensor and same data sheet it appears! The Motec one is more helpful for my application on a Dynojet Power Vision 3 EFI tuner as it has the temp scale based off of voltage for the ECU calibration. Second datasheet just confirmed. Thanks for your help!
