Gm 2 bar map sensor voltage chart.

749 861 the logic module uses the manifold absolute pressure map sensor to determine the absolute pressure not the relative to atmospheric pressure of the air inside the intake manifold and the atmosphere barometric pressure. Several different versions are available for normally aspirated and engines with blowers. All the diablo tunes i am aware of right now are using a 2 bar map sensor in place of the factory 1 bar sensor. These sensors accurately produce voltage or frequency as intake manifold pressure changes and the computer uses this information to measure.

Apparently it s a gm cheverolet performance 3 bar sensor which should have an approx. 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. Now at a slightly higher elevation reading flickers between 1 78 and 1 79v giving a reading of 0 9 psig engine load with the car off. The map sensor manifold absolute pressure has a 5 volt input and then reduces this voltage according to throttle opening altitude etc and sends the signal to the ecu.

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. Gm map sensor identification how to identify a gm map sensor. The pressure inside the intake manifold is an extremely important input to the ecu. 2240 0 1600 psi 2247 2 bar map sensor map voltage map output voltage offset voltage.

If you are going to run more than about about 15 psi max then you will need a 2 5 or 3 bar sensor but the tune will have to be scaled for it. Linear output based in this info chart shown is for a 2 bar scaling to 29 4 psi. Applications up to 30 lbs. So by supplying a higher or lower voltage the return signal is varied by the same amount.

This sensor will respond to changes in manifold pressures and relay the information to the ecu in the form of a voltage signal ranging from about 1 volt to 5 volts. Map sensor information for the ecu calibration crucial information for the ecu. 039 460 883 876 2 bar. The part is ac delco 12592525.

Nearly everyone is using the gm map sensors they are linear in output and readily available. 3 digit numbers for identification. Find chevrolet performance map sensors 12592525 and get free shipping on orders over 99 at summit racing.
