I,m just gonna use the "engine load" column. That worked really well and was pretty easy. No extra logging also.

 

i see trouble a head.
if ppl start doing this whilst load is fairly similar upto peak power after that load drops un proportionately to boost. so ppl will start thinking hmmm boost is tapering like a biatch and start winding up duty to stop it when actually your not looking at real boost

 

I agree, it's cheap for the omni 4 bar and SD is the shiznit!

 

Results can be improved with bar compensated formula:

=((LOAD/6.895)-14.7)*(BARO//100)

This way it will also "work" (aka get close to) in high altitude conditions.

This.

Or the opposite; my load stays rock solid at 240 from 4500rpm on up, yet boost is dropping gradually from 23 psi @ 4500 to 20 psi @ 7000 (ECU-controlled boost curve)
