Need Help Configing Boost With A PLX Module

[2therock]

I would like to try and log boost off my PLX Boost/Vacuum module by wiring into an EIO input.

Not sure it can be done here is a screen shot of what I have so far. Now what?

I was just setting up this exact thing today. The PLX Boost gauge ranges from 30psi at 5V to -15psi at 0V so the easiest way I could set it up without having to put all 51 increments in the list was to:

1. Click on List
2. Delete all entries from the list
3. Enter 5,30 at the top of the list
4. Enter 0,-15 below that.

This will give you the values you need for the 0-5V range and worked perfectly for me.

Thanks, I'll try it.
I'm in FL right now returning to GA Wed and will run it.
When will you be testing it?
Will this show Vacuum also? I don't mind too much as I can look at MPG trends but will configure it out if I can.

Here it is looking like vacuum will be shown. I have played with the numbers but cannot seem to get it to just do boost.
And it's yet to be tried live too so...

according to that graph, it looks like if you enter 1.6, 0 for the second set it will just do boost.

maybe 1.7 ,0

How does this look? PLX says 1.66 = 0 psi bit the PID would not let me enter -0.000, it had to have a digit greater than 0 to scale on the graph.
Next to bring it down to a 10psi max.

Surely you jest........



That graph clearly shows 0V = 0 PSI..

to get what you want, put in whatever Volts PLX says = 10 PSI (from the first graph it looks like about 2.8 = 10)
then put 1.66 = 0 (not 1.6.6)
