Gm 4 Bar Map Sensor Calibration

Chevrolet performance map sensors are high quality direct fit replacements for worn or malfunctioning map manifold absolute pressure sensors.

Gm 4 bar map sensor calibration.

We have packaged a high accuracy 4 bar sensor and calibration in the gm style housing. 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. When i click right on the last column choose change load index the small edit box shows its right value 2 92 bar. 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.

Options min voltage 08 max voltage 4 88 scalar 3 8 load offset 15 0 filter 10 frequency 0. 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. I want to run a 4 bar map sensor with kpro. 2 5 bar map speed density e38 ecm ls2 and other engines this enhancement contains the following features.

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. This housing can use the 1 or 2 3 bar map connector so there is no need to change your existing weatherpack connector. These sensors accurately produce voltage or frequency as intake manifold pressure changes and the computer uses this information to measure. In the options i checked show 5 bar tables.

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. 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. I changed it in the parameters.

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. This sensor meets the same calibration data and meets or exceeds all delphi specifications.
