Dash gauge needles jittery when out of range?

Post by jsmcortina »

Perhaps this is by design?

It seems that when the needles on a standard circular gauge are out of range the needle bounces around in an annoying manner!
e.g. CLT = -15C but the dash gauge has set itself to 0-100. It is jittering just below the zero.

I noticed this too. My TPS was unplugged and the gauge was bouncing slightly below 0%.

Same thing here with the AFR gauge. There's no wideband connected, the AFR value is 9.8 (AEM calibration) however the gauge is set for 10-19, and is jittering at ~9.8.

It stops if you uncheck "Peg needle at limits".

Yes, that is the new default behavior when out of range instead of wrapping around. The needle rattles against the peg.
As Reverant said, if you turn off "Peg at Needle Limits" it behaves as it used to.

I'm not sure I'm comfortable with this new behaviour, if it's a feature rather than a bug. It's too distracting and makes it looks like something is broken. Why does it have to rattle around when pegged at min/max? No physical gauge does that.

It sounds like this feature is supposed to be distracting - the intent is to call attention to a reading indicating that something is, in fact, broken.

Yes, it is supposed to be distracting or at least in some way know the value is out of range rather than just sit there pointing at the wrong value.

Since you've went for a more realistic look on the gauges (which is a welcome change of course!), why not a "needle stop" and a blinking "warning LED"?
