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.

Gm 4 bar map sensor calibration. 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 changed it in the parameters. Options min voltage 08 max voltage 4 88 scalar 3 8 load offset 15 0 filter 10 frequency 0. These sensors accurately produce voltage or frequency as intake manifold pressure changes and the computer uses this information to measure.

This housing can use the 1 or 2 3 bar map connector so there is no need to change your existing weatherpack connector. 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. 2 5 bar map speed density e38 ecm ls2 and other engines this enhancement contains the following features. 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.

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. We have packaged a high accuracy 4 bar sensor and calibration in the gm style housing. So i finally got my 3bar omni power map sensor. In the options i checked show 5 bar tables.

Chevrolet performance map sensors are high quality direct fit replacements for worn or malfunctioning map manifold absolute pressure sensors. When i click right on the last column choose change load index the small edit box shows its right value 2 92 bar. This sensor meets the same calibration data and meets or exceeds all delphi specifications. I want to run a 4 bar map sensor with kpro.

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