And for a 3 bar t-MAP from the site Jamie referenced above we have:
We are awaiting final specification data from Bosch on this particular item but customer information indicates the following calibration with linearity between points:
P1 -> 11 kPa at 0.25V
P2 -> 307 kPa at 4.75V
P = V * 65.77778 - 5.444444 (Kpa) === V * 19.4241 - 1.6077 (inHg)
And Bosch implies
P1 -> 20 Kpa @ 0.5V
P2 -> 300Kpa @ 4.5V
which would give:
P = V * 70 - 15 (Kpa) === V * 20.671 - 4.4295 (inHg)
So what do you guys think as I am looking for the 3 bar map as my car also idles at the bottom of the range.
