Need 03-04 Cobra IAT2/BAP sensor calibration curves

Been searching for days on the net and can't find them anywhere. Swapping over a Holley Terminator X ECU and need to wire in the IAT2/BAP sensor. Any help would be appreciated. Thanks

iat2 shares iat1 and ect transfer, bap gives hz signal, I haven't found anything for it. In my mach1 ecm it's unusable.

engine temp, intake temp, transmission temp all uses same calibration curve, attached previously voltage vs fahrenheit
Bap gives frequency based square waveform

ok got it thanks, but I'm sol as far as using the stock Cobra combination iat/map sensor for pressure as it's not based on voltage but hz correct? - yes you just edited I see thanks

so I should be able to use the stock sensor for temp but add a 2 bar and just grab the signal from a vacuum line.

If you are supercharged you need an IAT2 signal to determine when and how much timing to pull to prevent detonation. IAT1 only tells you the ambient air temp.

That's why I'm trying to use the sensor below the blower.

That's good, however your EFI system will need to have the over temp logic and corresponding ignition retard logic built into the engine management software or the sensor will have no effect whatsoever.
