Gm 3 Bar Map Sensor Calibration

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.

Gm 3 bar map sensor calibration.

Description map sensor gm 3 bar manifold absolute pressure sensor standard compatible with the ms3pro and all flavors of the megasquirt ems microsquirt ems. 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. 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. May god s grace bless you in the lord jesus christ.

In the future i suggest purchasing non holley sensors from stores that can provide the calibration data. Calibration is linear with 1 1 kpa at 0 volts and 315 5 kpa at 5 volts. It is possible that detroit is. Common gm linear calibration.

To wire a gm sensor 3 bar sensor you need to. 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. 2 5 bar map speed density ls2 v8 e40 ecm this enhancement contains the following features. Call holley tech and ask them if their 3 bar map sensor shares the same calibration as the ls1 3 bar map sensor.
