COS3 Map calibratin

[etmotorsports]

Trying to get the 2 bar map to work and it won't. Installed custom OS3. Works good with the stock maf try to use the 2bar and it is horrible wont idle for more than a few seconds and dies, idles very rich tried correcting ve table and no help still idles rich. Any ideas.

In order to get the bar be right i have to enter a number of 448, the OS manual says to start with 190 but that is no where close.

I think i found the problem the customer gave me a map sensor i checked the #'s a few weeks ago and it showed to be for a truck, well i checked the numbers a while ago and it is for a Duramax, that makes sense why it won't read the vacuum correctly DOH. Should have looked into it more when he dropped it off.
