Hi all - I hope someone can help as i'm scratching my head a little. I'm trying to linearise this TMAP sensor (part Bosch 0261.230.333), and the spec is attached.
Range is 0.1 - 1.1 bar, which is easy enough. But it starts with a negative offset, and i've not seen that before. Can anyone shed some light on how to set this up?
Thank you :)

I think the offset represents the voltage at the 0 bar value, the voltage at 0.1 bar would then be -0.00476 + (.1 * 4.048) = -0.0048 + 0.4048 - 0.400
So .1bar is 0.4 volts, and 1.15 bar is 4.65 volts.
Thanks David, that appears to have done the trick! The data seems reasonable, showing a 47mbar depression before the compressor near the rev limit. That's about where I expected it from using hand gauges.
