GM 3 Bar Map Sensor Evoscan formula?
#2
Hi,
The formula given to me by tephra is:
0.17573*x-14.5
You then need to apply a correction for your altitude to give a baseline of 0psi
Eg: my actual formula in Evoscan reading request 38:
17573*x - 14.058
Cheers.

I have not done it yet as i wanted to make sure i had the correct info before starting but from what i,ve read i believe that pin 92 is correct for the signal and that is mut38 which is already set up in evoscan under JDMmap it just needs the new formula.

kpa is always absolute...
so at IGN=ON, engine=off the kPa should read 101ish.. at sealevel...
edit - if you want to remove atmo pressure then just subtract 101 (or whatever your atmo pressure is) from the end of the formula
