Sorry my mistake.
It would be alpha-n.
The map sensor could still be used as an altimeter, so to speak,if wanted, with a correction scale for basic barometric change as long as it was in a stable spot such as a ram air scoop for the intake system along with the intake air temp sensor, could also be used with data collection to see if the scoop works/ram air etc.
either way the engine has to be mapped out on a dyno for correct A/F etc.
