Map sensor gm 3 bar manifold absolute pressure sensor standard compatible with the ms3pro and all flavors of the megasquirt ems microsquirt ems map sensor assembled in the usa unlike the current delphi production calibration is linear with.
Gm 4 bar map sensor calibration.
Formula for the gm 3 bar map sensor is v 8 94 14 53 i have no idea why it s 14 53 and not 14 696 rounds up to 14 7 but it works out on gm s chart every time.
It is possible that detroit is slightly above sea level and you can use 12 11 in the formula for 1 mile above sea level.
I have a brand new motor being built now at golden eagle and a head being built at bisimoto enginerring so i will be using my old calibration and having it retuned this spring but i just want the map sensor to be bang on and the scalars and offsets are diff from the gm and the motec from the research i have done this must be why on my last dyno pull my ecu was reading 16psi and the.
I tried to change the multiplier and offset but it is not possible to use positive offset in my 16bit ecu 3 bar multiplier 9 119 psia v offset 0 164 psia so i have a useless map sensor right now.
In the options i checked show 5 bar tables.
This sensor meets the same calibration data and meets or exceeds all delphi specifications.
These sensors accurately produce voltage or frequency as intake manifold pressure changes and the computer uses this information to measure.
We have packaged a high accuracy 4 bar sensor and calibration in the gm style housing.
It is possible that detroit is slightly above sea level and you can use 12 11 in the formula for 1 mile above sea level.
I want to run a 4 bar map sensor with kpro.

When i click right on the last column choose change load index the small edit box shows its right value 2 92 bar.
2 5 bar 255 kpa max map sensor support calibration capability for gm 0 5v linear map sensors rescaled high maf table supports up to 15400 hz with 300 hz resolution also supports airflow up to 1024 g sec.

But in the tables itself the table scalers are just showing up to 1 9 bar.
