Two Brothers Racing JUICE BOX™ PRO - Premium Fuel Controller

Juice Box Pro adds performance with map storage, computer optional full customization and the ultimate in PC-based tuning capabilities to the proven Juice Box fuel management platform. Two Brothers Racing, continually dedicated to Top Level Performance, dials in Fuel Injection performance like never before with the Juice Box Pro. Offering memory capacity for up to 10 fully custom fuel maps and virtually limitless tuning potential, the Juice Box Pro revolutionizes the plug-and-tune category of performance electronics. 

Custom-Designed Fuel Mapping

Juice Box Pro is the only fuel management interface to offer preloaded, dyno tested bike-specific mapping and the ability to fully customize and build your own Power Maps via computer in a simple to- install, user-friendly component. Through TBR’s Direct Injector Control, the fuel circuits on current sport bikes can be modified both richer and leaner than stock as much as -100% to +250% in any particular area of the power spread with the Juice Box Pro. Also, up to 10 pre-programmed TBR Power Maps (custom made and dyno tested for each Two Brothers Racing exhaust system) are adjustable to your preference. Riders can literally select between a TBR Power Map, custom-built maps, or even fine tune low, mid or high rpm ranges while sitting on the bike and without plugging in to a computer. Standard +/- 10% increments from selected map settings, different ranges are available using the supplied Top Tune software. 

Computing Power

For racers and riders looking for the ultimate in precise adjustment and fuel map customization and creation, Two Brothers Racing’s Top Tune software allows PC-based Power Map creation at 250-rpm increments and 10 different throttle positions. Modification parameters vary upon make and model of machine and fuel changes made in these increments are automatically interpolated between the rpm and throttle position ranges ensuring a smooth final power curve./span> Users can load up to 10 of their personally built Power Maps into the Juice Box Pro and select between them while in the saddle— eliminating the need to “re-boot” with the computer every time a new map is desired. 

  • Uses OEM style connectors and high quality wiring harnesses.
  • Small, Lightweight and Easy-to-Fit on the bike
  • Pre-programmed with TBR Power Maps specific to make, model and style of TBR Exhaust and/or TBR Pro Filter
  • No computer necessary for Top Level fuel management
  • Fully adjustable computer compatibility for ultimate tuning and personalization
  • Software is compatible with Power Commander, so you can download Power Commander maps to the Juice Box Pro

Very responsive bike after My JuiceBox is paired with TwoBros full exhaust. I've contemplated on switching to a new bike. Honda CBR 600RR to be exact. But decided to give this product a go in hopes of reviving my 250 and maybe try and make it fun again before dumping 6-7000 dollars. The product is very well finished. No cheap wiring, plastic and such. So it's not going to fall apart at a first touch. I did find the installation to be a bit confusing and difficult. Nothing a novice couldn't handle really. But the part where it says to thread it (or something like that) behind an air box screw was the confusing and difficult part. To be able to do that, I had to take of, or somewhat pry up, the tank, unbolt the four bolts on the airbox because if you did only one, the airbox still wouldn't budge. So, take the tank off, and then airbox. This was too much work for what was supposed to be simple install. I just ended leaving the wire outside the airbox bolt. It's not going to rub against anything anyway. The rest of the instructions were fairly easy to follow. After the install I took it for a spin and noticed an immediate difference in throttle response. Also noticed a small gain in quickness of the bike, but throttle response is where it's at. The bike will shift proper without any hangups, split second delays and such. It's BANG BANG BANG and you are in 6th basically. I wouldn't say that it's worth what they are charging, but that's just my opinion. Maybe take off $50 and it would be fair price. Overall I am happy with The Box. It definitely revived my bike for few more years use. July 18, 2014
For CBR250R Bought this back when i had my little 250. It made a decent difference on it. I used it with thew 2bros full system. It definitely made a difference in the power. May 23, 2014
Best $200 I've spent in a while I installed a Leo Vince Evo II full exhaust on my '13 CBR250R mostly for the sound, it made a small difference according to my butt dyno. After doing a lot of research i learned that the CBR250R runs lean from the factory and the exhaust can cause it to run even more lean. I installed the juice box pro and rode it the next day... WOW, what a world of difference. Smoother idle, smoother revs, the bike just runs so much better overall, and a noticable increase in throttle response. Bike definetely feels faster. I am very impressed! I am currently using the 2bros Slip on tune that came with the unit, so it will only get better when properly tuned for my setup. Install was easy, but had its moments of frustration, instructions and pics could be better. But if you have any kind of mechanical skill, you could pull it off. Definitely have someone help you. Alll in all, great product, you won't regret it! August 15, 2013

A shopper asked: I bought this and can't figure out what other pre loaded maps it came with. It only shows 3 of the maps in the manual out of 10. Anyone know what's pre loaded for the cbr250r juicebox? Jun 24, 2014

Skyler H: Mine only came with two. One for an aftermarket pipe and one without. You can make and install a total of 10, but honestly 1 of the three you have should cover it. You can also tweak the settings +/- up to 5% with the low, mid, and high "dials". I found either of the maps +5% on the low mid and high was perfect. Hope this helps Jun 24, 2014

oussama a: Install the software from the CD that comes with it then you can see all the maps. You can also download other maps from dynojet website and load them into your juicebox. Jun 25, 2014
