log boost with JDM MAP sensor (updated instructions)
#496
The lower the idle, the lower closer the pressure will be to zero. -8 to -9 psi is typical for 850 rpm. If your car is idling below that, the pressure could be less. Also, I think aftermarket cams can affect the pressure at idle

My idle is high for some reason could be due to the bad maf wont know for sure till tuesday.
As for cams i have 272 hks I&E cams, hks suction reloaded intake, hks evc, hks tbe, all of this was bought with the car plus a boost gauge and old dyno flash tune. Not sure still what else is done to it. They said there was 10k invested by previous owner but who knows.

What should be in the protocols. xml for Logworks? I'd like to check my work.
Looking at it, I'm set at 0 & 30 for the min and max by the look of it. Probably the problem. What should be the "min" ?
Or is this just wrong?

Thanks boss. Will that change the scale in comparison to what I have been seeing? Like by starting at "0" have I skewed the output scale? Or is it just not showing me values below "0".
Just wondering.
Guess I'll go for a log and see. I haven't changed the boost since my last trip out logging.
