Posted in an existing thread in the gen 4 section but they weren t much help.
Gm 3 bar map sensor pinout.
Map sensor gm 3 bar manifold absolute pressure sensor standard compatible with the ms3pro and all flavors of the megasquirt ems microsquirt ems.
To wire a gm sensor 3 bar sensor you need to.
It is possible that detroit is.
Map sensor assembled in the usa unlike the current delphi production.
Chevrolet performance map sensors are high quality direct fit replacements for worn or malfunctioning map manifold absolute pressure sensors.
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.
Holley products for gm s popular ls engine are dominating the ls scene as well.
I am building a 02 lq4 with lsa heads and a ls3 intake and was wondering if the 12592525 3 bar sensor off the ls9 would be a plug and play with the correct harness using the custom 3 bar sd os on a 02 silverado pcm.
These sensors accurately produce voltage or frequency as intake manifold pressure changes and the computer uses this information to measure.
Calibration is linear with 1 1 kpa at 0 volts and 315 5 kpa at 5 volts.
Holley s products also include performance fuel pumps intake manifolds engine dress up products for street performance race and marine applications.
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.
