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.
Gm 3 bar map sensor pinout.
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.
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.
To wire a gm sensor 3 bar sensor you need to.
I am about to install a gm 3 bar map sensor.
Map sensor assembled in the usa unlike the current delphi production.

Map sensor gm 3 bar manifold absolute pressure sensor standard compatible with the ms3pro and all flavors of the megasquirt ems microsquirt ems.
It is possible that detroit is.
Posted in an existing thread in the gen 4 section but they weren t much help.
My boost safety will stop it from going above 30 psi.
I checked a motors book that covers all vehicles from 77 83 and it says in the diagnostic section for map vac sensors that the pinout is a low what s that ground b output and c v ref is this the 5v or is this the ground.
What happens if i overshoot and hit 29 plus psi.

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.
You need linear per five.
Calibration is linear with 1 1 kpa at 0 volts and 315 5 kpa at 5 volts.
That screen shot is showing the linear per volt.
I don t plan on running over 26 or 28 psi.
It s the same as part 0 281 002 437.
Holley s products also include performance fuel pumps intake manifolds engine dress up products for street performance race and marine applications.
A 20 300kpa sensor that uses characteristic curve 1.
The gm map sensor is the same as msd 2311 1 bar map sensor.
In the vehicle specific repair book it s ground.
The 3 bar map should go to 29 psi.
Discussion starter 1 apr 16 2006.
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.
