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. Before we get started, let me tell you that this tutorial will show you how to do a map sensor bench test This garrett tuning guide explains common gm map sensor configurations and highlights important compatibility considerations for gen 2 lt, gen 3 ls/vortec, gen 4 ls/vortec, and gen 5 lt applications.

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. This guide from our friends at pcm of nc is a complete lifesaver Especially for remote or mail order tuning Correct map sensor data is imperative for proper tuning.
Is there a way to identify a 1bar, 2bar, and 3 bar map I think i have a 2 bar map, but it is way off according to my calmap program The input voltage is 4.68v I am wondering if i have the right map.
