If you dig in the pcm section you should find some info about running a 2-BAR MAP, it compromises resolution though because the pcm is really only meant to handle 1BAR. That is a recent thing though people made it work single bar for a LONG time. People have found workarounds for a LOT. By the time you get all the tuning figutred out at substantial cost you might actually consider aftermarket management setup for multiBAR MAP.
the problem with 1bar is you only have your 100kpa graph bar to tune your timing and afr . the prob with that is if you are running ..say .. 15 psi..as soon as you go wot it hits that 1 bar on the grapghs to reference and loads it with fuel and low timing before it even hits boost. Its just a slopy way to do it.Ive been running the two bar and it works great. This setup only uses 50kpa and under for n/a tuning(when not in boost) then 55kpa and higher for boost. so now you have a bar for like every 2-3 pounds of boost rather than being stuck with the one 100kpa section of the graph.Its alot better all around and all you need is a 2bar and lt1edit or tunercats for programming.
