Incorrect boost on Scanner

[jwhitten]

I feel like im in algrebra class again lol

[S2H]

So do ([sens.30.psi]-14.5038)*(0-1)?

that should work...I'm not in front of my laptop right now so I cant confirm it
or you can also do
-1*([sens.30.psi]-14.5038)

Thanks I will try that out here in just a little bit.

Yeah I now what the help section is and I have tried to get that one to work to I am just PID illiterate lol, is there a way to get it to read both boost and vaccum? or is there another PID that you can make to read vaccum?

Post #16 has the information needed. Worked too. I created a new Gauge in the Gauge Display, and in the properties I linked the PID to "Boost", the Max number to 30, Min to -10, Ticks to 9, and POOF we have a round gauge that says BOOST and clockwise from about 7 o'clock it displays -10, -5, 0, 5, 10, 15, 20, 25, 30 ------------ juuust like a real analog gauge. At idle it displays -10psi, and right on up to 23 psi. I also added the BOOST to the charts with the same settings.

It still will not work for me at idle it shows -10 which is 10.5 off from what I actually read and when I rev in neutral the pointer goes to something like +10psi when it actually only goes to like -2 so you see I still have problems I just gave up on it because it does not work for me. I am fine converting it myself at least that way I can get it to work.

This goes back to the posts about how the MAP reads while a boost gauge will read 0 at 1 atmosphere. The formula will get you very close to where you want to be on the BOOST gauge that was created vs. the MAP gauge that will rear about 14.5 psi at idle. (This assumes I have explained it correctly.)

post your scanner config file...
let me load it and see if I can figure out what you are missing...

so you say to run this: ([sens.30.psi]-14.5038)

i am using this: [PID.2333.IMP]-14.5038

is mine wrong?? I read negative numbers untill it gos to boost and reads positive.

Think of the negative numbers as vacuum like you'd see on a boost gauge, i think -10 would be around 20 inHg.
