Gm 3 Bar Map Sensor Wiring

To wire a gm sensor 3 bar sensor you need to.

Gm 3 bar map sensor wiring.

That screen shot is showing the linear per volt. 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. It s the same as part 0 281 002 437.

A 20 300kpa sensor that uses characteristic curve 1. Map sensor assembled in the usa unlike the current delphi production. 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. 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. 20kpa absolute 0 300v 300kpa absolute 4 900v mechanical connection via 3 16 hose connector nipple the linear calibration for this 3 bar gm delphi map sensor is already pre loaded on many aftermarket ecus including the range of link g4 and vipec i series ecus. Calibration is linear with 1 1 kpa at 0 volts and 315 5 kpa at 5 volts. 0 4v is 20kpa 4 65v is 300kpa work the mx b and you ll find a map sensor linear of 329 41kpa and a map sensor offset of 6 35kpa.
