Hello , I have a Magic Pie 5 I ride most every day for exercise and fun ... It has a cruise control feature I like and use a lot ... sometimes if the bikes bouncing along when I'm trying to set it I'll set it to high or low ... I've seen this switch with plus and minus to set the speed ..Anyone know if this could be used with a Magic Pie 5 controller ... Any where I can buy one or something like it .... Thanks in advance for any help you can give 30ded23574f6c0670a5bf8af9c4d3b48 (1).jpg
As long as you're willing to either make yourself an adapter cable between the throttle, ebrakes, magicpie, and cruise unit, or cut and splice wiring, then yes, you can use the Crystalyte cruise unit with it. All it does is read and hold the throttle input voltage when you engage cruise, and then let you adjust that voltage up and down in steps with the +/- buttons, and disengage cruise with the ebrakes (or the button), so it works with almost any analog-throttle system.
Crystalyte's homepage http://crystalyte.com has an accessories page that still lists the device, so they may still sell it.
If they don't, you can use the Cycle Analyst to do the same job, more or less, though it requires you to do some setup in it first, to "tune" it to your system, and it is more expensive and larger. (but also much more useful if you have need of it's other functions, like monitoring your power usage, battery capacity, etc). To use the CA to do it, you'd need the CA iself, plus the DigiAux control unit, and then the right connectors and wiring (which you'd probably have to make) to put the CA between your throttle and brake controls and the MP wiring. The CA has a cruise mode you can set to engage after whatever amount of time you want, then adjust the throttle out limit with the DigiAux. It's not the same behavior as the CC unit, which is much easier to wire in and use (no setup required), but it will probably do enough of what you want once dialled in.

The relevant setting section is quoted below:
[ AuxD->Function ]
Chooser to select the controlling effect of the digital control. Choices here are identical to those of the Aux Analog function selections but are mutually exclusive so a selection made in one will be excluded from appearing as an option in the other. This option is not present if no AuxD device is installed.
ThrO Lim: The Aux control applies a scaling factor to the configured MaxOut voltage. This has the effect of limiting speed by a means that is easier to tune than true speed limiting.
