Joystick Throttle Calibration

[sim]

I'm a KSP veteran, but I recently took the dive and got a Saitek x52 Pro HOTAS. I have the actual joystick working extremely well. It's the throttle that's causing me problems. With the throttle all the way back (0%), KSP is setting the throttle at 50%, meaning I only have control of the throttle from 50-100%, which is slightly less than desirable.

I'm on Linux, but that doesn't have anything to do with the values sent to KSP. I've used a program called jstest to view the raw data coming from the throttle, and I think I've identified the issue. When the throttle is at 0%, the data reading is 32767. As the throttle increases to 50%, the numbers decrease to 0, and then negative. At 100%, the data value is -32767. It seems like there should be some way to tell KSP that the throttle doesn't operate with data values 0--whatever, and instead is whatever--0--(-whatever).

Has anyone else run into this issue?

It could be this bug? http://bugs.kerbalspaceprogram.com/issues/1152

Or one of these: http://bugs.kerbalspaceprogram.com/projects/ksp/search?utf8=%E2%9C%93&q=joystick

This annoys me so much. Probably unity's fault though so there's not much they can do about it.

they could just bypass unity's input setup and roll their own...

Darn, I was hoping that I just needed some manual tweaks to settings.cfg.

Thanks for the tip. Looks really interesting. I hope a Linux version is coming soon.

Try putting your throttle stick at half way when setting the bindings. Worked for me.

Yeah, unity calibrates axes on startup... and zero is actually "50%" on the throttle.

It's pretty annoying as it needs to be exactly centred every time you start KSP.

IIRC, there's also a "scale" value in the settings file you could muck with if you find you're still not getting full throttle range.

Unity joystick/controller support is horrible.
