can someone explain to me the pros and cons of the juicebox on a can am spyder. is it worth the money and does it help with fuel and performance on the bike. thanks

I have a two Brothers single and K&N air filter. Because the Spyder was sputtering on deceleration, it was determined that the bike was running lean (common). I installed the juice box pro, with a downloaded map from power commander. This map is available on their website, and is specifically designed to correct the lean fuel issue with a 2bros. Single exhaust and "green" air filter. No issues now, nice and smooth. I am not an auto mechanic by any means, but install was pretty easy. That's my experience with the juice box. Hope it helps. It depends on your set up. If you are stock, you don't need it in my opinion.

I have a power commander on my 2011 RS - what is the difference between a power commander and a juice box?

If the Juice box is only controllable in 10% increments, then the PC is far more tuneable. More difficult to do, because you have to do it via computer, but you have almost infinite choices as to the mixture and at what RPMs. The way PC's usually work is to tune it on a dyno with an AF analyzer then that dyno tune is available for download. Then you can choose various tune maps off of the PC website or other internet sources to find a good one for your individual bike.

10% increments for the Juice box is very crude, usually they are in 5% increments for other such devices.

I've got a JBP; while it's true TBR's JBP literature says the low, mid, and high range are adjustable in 10% increments...............I'm not so sure that is literally the case. All three circuits adjustment is via small (#0) Phillips head rheostats. Each is surrounded by hash marks; corresponding to the hour positions on a clock face. There are NO detents at the hash marks; so turning the rheostat in counterclockwise (leaning it out), or clockwise (richening it) is smooth and progressive, like a dimmer light switch. I assume the hour mark hash marks are to indicate the 10% leaner or richer settings; with anywhere in between any two hash marks to be an additional percentage leaner or richer. e.g. Halfway between the 11 and 10 o'clock hash marks would be 15% leaner. My experimentation with this tuning feature bears this out. I've never had such an easily adjustable fuel management tool (as I fondly :gaah: recall previous experiences of hours and hours and hours of jet changing trial and error fun on multi cyclinder carb banks!). The JBP allows very quick and easy (open the hood, pop off the fuse box/JBP cover and twist a rheostat with a jeweler's screw driver) adjustments/experiments. Additionally, I received a "Top Tune" software disc, and USB cable (haven't used either) with my JBP. Any fuel maps included with the TT disc may be installed into any empty map slots in your JBP (there are 10 total; the # 4-9 positions are empty). You may also adjust (in your computer) any of the numerical values in any of the fuel map cells in the TT fuel maps. The example TBR uses is either -10, or 10; being 10% leaner, or 10% richer, respectively. The b & w image of one of the JBP fuel maps shows some cells with numerical values smaller than -10/10, i.e. -4, 7, -5, -15 etc. I have a Power Commander III on my ZX14. My understanding is you can install custom maps, or adjust the one it came with (mine was expertly developed on a dyno for my engine/pipe combo by Kyle Racing and dynoed at 185+ RWHP.................needless to say I haven't :cus: around with it!) by connecting a notebook comp to the PC III with the obligatory USB cable, then installing a map or by adjusting individual cell values. I have no experience with the newer self tuning capable Power Commander V....................I've heard nothing but good things about them though.
