is the bap the same as the map sensor and if not where is the map sensor i thought the bap sensor was used on speed denisty only

88 GT CONV

map = manifold air pressure
i think bap = barometric air pressure, but not 100%

They are different though

In SD systems it's called a BP/MAP....it does both functions.

In MA systems it's called a BP or BAP sensor...its functions as a MAP sensor are not used, nor required.

It's the same sensor.

alright thanks im trying to figure out my popping through my intake under light xceleration

Run the self-tests....if you have a bad BP/MAP sensor or circuit (wiring, connection, ECM).....expect to see a code 22.

When you do a SD to MA conversion, you simply remove the vacuum line from the MAP sensor and leave it reading atmos. pressure.....it's now a BP sensor, you don't replace it.

if i left the hose pluged into the intake would it make it run like crap if i did a mass air conv

Ohh Yeah!.....
