Gm 3 Bar Map Sensor Calibration

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.

Gm 3 bar map sensor calibration.

Map sensor assembled in the usa unlike the current delphi production. 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. 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.

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