MSD 6010 map sensor 2bar 1bar ??? I need a GM part number for a map sensor for my 6010 setup. The car will see max of 10psi so will 2 bar be ok? I dont know what the factory map will support or how many bar it is capable of measuring. I have one on it temporarily from a 2.2l s-10 which should be alright for now (no boost yet) but I would like to replace it asap

a 2 bar will be fine, i think the one i used was off a supercharged colbalt, i will read the # off it later today-it looks just like the one used on ls6 intakes, only 2 bar
when you switch the msd program to 2 bar, it opens the graph to 0-30
im not much of a computer person, so it was hard for me to figure out, but the dyno guy did it
what i found out, and you may know this already, with the engine off, it will read 14.7 or so(sea level)-when you fire it up, that # will lower from the vacume-i found on mine, it will roughly take about 2 psi of vacume to lower i psia of atmosphere-if you have 14 lbs vacume, you will read around 6-7 on the map scale at idle, so you can set your idle timing there-as you nail it, and the vacume goes away, the psia goes up, xero vacume and your back to 14.7, then as boost takes over and its 1-1 on the scale above 14.7
10 lbs of boost, you might read 24.7 on the graph
i ran mine using the map sensor, but might switch to the timing rpm graph, one less sensor to fail, lol
