yes the aux block has a terminal marked MAP , you need to run the signal from a map sensor (pin B) to it , you also need to make sure you have the scanmaster data wire run to that blocks SCM terminal to recieve data from the PL as well as having the pl updated to the latest version
if you have a three bar sensor for alky tap the geen map wire , if you just have the OE 2 bar sensor the map signal can be tapped from the green wire at the connector where the engine harness connects to the dash harness behind the glove box
a 3bar sensor will alllow boost reading to about 30 psi , the two bar will allow logging up to 15psi
