tried all that stuff again with no luck.  Must be something to do with just the karts.  anyway, I found a 3 way slider switch on the back of my tach.

Surprisingly enough, that fixed my problem.  The switch has 3 settings....center is normal.   For instance, center is setup for normal cars, if you were at 4000 rpms that shows 4000 rpms, if you switch to one direction, the 4000 shows up as 8000 rpms, if I go to the other setting of the switch at 4000 rpms it shows 2000 rpms.   Crazy me, I've been looking for the manual for this tach for months online.  I found one close but not the exact one I have but it showed a switch on it.  I looked on mine and it was there....problem solved.  Lol, I was getting ready to open it up and cut the wire to the alarm.

Have a nice weekend

Have a nice weekend!

you can do it in simhub:

first select your game after select "car setting" tab on the left

and on "setting by car" select your kart and check RPM max, at this point your can add the max RPM just for this vehicle

enjoy

What I'm talking about is an "override"  area that is enabled after the game starts up.  It has a drop down choice of every car in the game including the karts.  The karts are the only one that revs that high so I would rather leave my initial settings alone.

i am not sure to well understand...( i am not english) but if you just need to send data to your tachometer at 22.000 RPM you can try

Simhub>Arduino>Gauge and select 22 RPM  and 1 cylinder for kart

hope this is what you are looking for... see attached picture but in french...

edit: may be no need 1 cylinder; it depend of your tachometer indeed...

Maybe you can shed some lite about this question...

So, with everything running,  Btw I'm using Project cars 2,  When in the game I found the area of the tach override for Karts. I just Alt tab out of the game to setup Simhub overrides.

The only problem is I can't figure out what numbers to put in the boxes.  I've tried High and low settings but the tach still goes off at 11000 rpms like a normal automobile.  Of course the karts run about 21000 or 22000 rpms.   Can ya help a brother out?...lol

Thank you,

Graveyard

Can anyone direct me to the proper location of that setting?

Thanks,
