boost/vac gauge

Post by msegt »

im looking to get a boost/vac gauge back into ms2's gauge settings for ts. i added an afr target gauge, and the boost/vac last night into the gauge settings lines in the INI file using this.

VacBooGauge = boostVac, "Engine Vac Boost", "in-HG/PSIG", -30, 30, -30, -30, 30, 30, 1, 1
TargetAFRGauge = TargetAFR, "Target AFR", "AFR", 10, 19.4, 0, 0, 20, 20, 2, 2

so far i got the afr target gauge working, but i cant get the boost/vac to work right, its just reading map pressure and is totally off on the gauge to where it should be. what am i missing, what else do i need to change to make this work right? i cant find a channel for engine boost/vac, what do i do now? i take it i gotta add this also somewhere?

Vacuum and Boost Gauges
vacuum = { (barometer-map)*0.2953007 } ; Calculate vacuum in in-Hg.
boost = { map < barometer ? 0.0 : (map-barometer)*0.1450377 } ; Calculate boost in PSIG.
boostVac = { map < barometer ? -vacuum : (map-barometer)*0.1450377 }

but im new to playing with the coding and just trying things out, if anyone wants to lend a hand. im basically looking at the old ms1 INI i was using prior to ms2 and figured id see what i can make work.

thanks,
josh

looking at your ini entries, I couldn't see anything wrong, so i tried it out on an MS2e.

The only thing wrong on MS2e was the name of TargetAFR as an OutputChannel.

I corrected that and put it in the attached custom.ini and the boost / vac gauge seems to work fine.

If you put this in the folder:
[YourProjectFolder]\projectCfg\

Then when you right click on the gauges you will see a category called "My Gauges"

works great, awesome thanks a bunch man. thanks for such a fast response. any clue what i did wrong in the ones i made up? my afr target worked on the first one i tried too, just the vac/boost didnt show up in the channels part. afr came up as afrtarget or afrtarget 1 i think.

The ini file supplied with MS2/Extra 3.2.1 already has a vac/boost gauge.

Although it looks like target AFR isn't there yet.
