What is the 3 bar MAP sensor?
 

through me a bone.......I don't know what it is or does....I told you I don't know crap about a EMS =)

The LT8 comes standard with a 20 PSI MAP sensor. The 3 Bar MAP option replaces the 20 PSIg sensor with one that can read up to 30 PSIg. If you need to run more than 20 PSI, or wish to be able to control when boost spikes occur, it's the 3 Bar for you. :)

So what your saying is, It's used to run up to 30 psi boost? I don't meed that. I should be able to make all the power w/less then 20pis of boost. So, I guess I don't need it. Cool.

If you have an external and it ever goes bad you can go to any GM dealer and get the GN boost sensor, cause that's what it is. If your internal one goes bad you've got to send your whole computer back to Microtech (or Brandon) and wait... :)

What do you meen "external"? We don't use our stock boost sensor do we? I thought the 2 bar or 3 bar was built into the LT-8 in's self..........................

help me better understand

the 2 bar is built into the unit, the 3 bar is external of the unit, the 3bar is a GM sensor.
