I would like to use the shift lights to assist steering direction on a land speed record using a C125. I have accurate heading from a CAN input. So the centre light would come on when heading, say, 300 deg. the light to the left would come on at say 295 deg and the light to the right at 305 deg. Possibly at different brightness so it would get brighter the further away from 300 deg you were steering. I am using Dash Manager 6.51.12. Is this possible with this dash? Any alternative suggestions gratefully received to help keep driver/rider heading in the correct direction! Thanks

I think something like this would work. Channels we are using as follows. n this case

GPS heading, actual vehicle heading

Compass bearing. This is the target heading, set as a constant, in this case 300

Course variation. How far off course, uses a 3d table to do the maths. Negative numbers off course one side, positive numbers off course the other way. I've made it simple with the 300 heading only for example purposes.

Light 1 true when course variation is less than 0 brings on light 5, green
Light 2 true when course variation is less than -3 brings on light 4, yellow, plus the above green stays on
Light 3 true when course variation is less than -6 brings on light 3, red, plus the above green and yellow
Light 4 true when course variation is less than -9 brings on light 2, red flashing, plus all the above grn, yel, red

Some disclaimers, I don't have a dash here now to test this, and it's 10pm saturday night and I'm cooking up a config for fun, so it's just my best crack at it. You'd have to decide what the hand of the lights mean, steer toward or away from the lights.

The slm lights are priority based , top of the list has highest priority, so as defined the upshift lights override the heading lights.

Let me know if it does, or does not make sense. Regards, Sean

Thanks Sean. I actually made a fairly similar solution on Friday PM and was that pleased with myself I forgot to look at the forum! I made some user conditions bracketing heading errors then used each condition to activate light(s). I think it amounts to the same idea as you but will have a look at your version and learn from it. Many thanks. Ben
