Gm style 3 bar map sensor with pigtail 35 00.

Holley products for gm s popular ls engine are dominating the ls scene as well. Next video will show the installation of the hp tuners 3 bar enhanced os. I plan to use a stock gm 3 bar zr1 map sensor a 35a mac valve afr signal and a few outputs. In this video i test the map sensor and calibrate an arduino based gauge to output correct pressure.

3 digit numbers for identification. The pcm simply sees 0 5v from the map sensor. 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. Choosing a 3 bar map sensor when map values do not exceed a 2 bar map sensor s range results in loss of lookup table resolution definition for proper fueling.
