Next video will show the installation of the hp tuners 3 bar enhanced os.
Gm 3 bar map sensor wiring.
You need linear per five.
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 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 assembled in the usa unlike the current delphi production.

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.
It s the same as part 0 281 002 437.
