Gm 3 Bar Map Sensor Calibration

2 5 bar max map sensor support calibration capability for gm 0 5v linear map sensors new boost ve table from 105 kpa to 255 kpa 2 5 bar or 22 5 psi boost retains stock ve table resolution in non boost regions.

Gm 3 bar map sensor calibration. In the future i suggest purchasing non holley sensors from stores that can provide the calibration data. Description 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. It is possible that detroit is.

Run a single sensor output wire from pin 1 square of the map holes on the pcb to a free pin on the db37 use 25 which can be connected by running the sensor output wire you just installed to x11 on the pcb then run a wire from this pin 25 on the db37 to pin b on the sensor. 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. Looking at the calibration curve for the custom 3 bar it appears that holley stopped at 26 8 and 4 5v for the 12592525 sensor. Common gm linear calibration.

To wire a gm sensor 3 bar sensor you need to. Calibration is linear with 1 1 kpa at 0 volts and 315 5 kpa at 5 volts. Call holley tech and ask them if their 3 bar map sensor shares the same calibration as the ls1 3 bar map sensor. If in between two custom map sensor options such as 3 5 bar you must select the higher of the two 4 bar and correctly calibrate it.
