2Bros Juice Box Pro install

Just purchased Juice Box Pro from 2Bros, am assuming this will require an ECU reset once installed. Have seen the you tube videos and read threads on the process, any addition info would be helpful, on either the install itself or the ECU reset.

Like a Power Commander, piggy back fuel controller.
I just talked to someone in tech support at 2 Bros and was told that it will be a couple more weeks before they're released. "Still in testing right now...."

Hope not, have been posted on their website for a month at least.
Made my order (thru 3rd party) assuming they were in stock, if not will be asking for refund.
Just double checked Surfside Motor website (were I ordered) no mention of out of stock or waiting time, will be pissed if they have taken my money with no mention of waiting time. IMO people shouldn't sell stuff they don't have in stock without telling you upfront. Lucky I paid with PayPal.
Found this comparison of different fuel management boxes on the 2Bros site, interesting! Scroll down to the bottom of the page.

When I read about it though, it says that the custom maps are designed to each different 2 Bros exhaust. In the end though, if you're using a non-2 Bros exhaust, you will still have to do some tuning yourself (that's what it seems like to me anyhow).

Also, on their downloads page, there are no custom built maps yet for the CBR250R yet.

If anyone has any experience using software to tune the maps on such a device, please post.
No reset

Reset will no longer do anything with any piggyback fuel box. First thing you do upon installation is disconnect the O2 sensor which will lock the stock computer to a fixed mode where the fuel box can modify the stock maps from there.

I've got a sneaky hunch that there's not a whole lot of difference between different manufacturers' products for the average street rider from the standpoint of fuel maps. For instance, a map that will work fine on a 2-Bros with insert will probably work just as well for others that also have an insert.

But then there is also no listing for the CBR250 unit itself. I'll bet that the downloads will show up when the testing is finished and the units get shipped.

OK thanks I have heard of a power commander but not a juice box. One and the same

your first point is well made, I chose the 2Bros because I have their slip-on installed and also like the ability to change maps without plugging into PC.
The CBR250r Juice Box Pro is on their website here:

thanks for the info dude. Disconnecting the O2 sensor to lock the ECU in place seems commons sense, now you've mentioned it.
Cheers
Looking forward to feedback once it's all up and running.

Will you be able to change the powerband with the J/B? So the power doesn't peter out at 9k rpm but keeps going until 11k?

To be honest dude, I don't really know. First time I've done this sort of mod, so it will be a bit of a steep learning curve to start with. Which is why I stuck to same brand as my exhaust and a simple "plug in and ride" system with pre-made maps from manufacturer. Once I get used to it and read some more about fuel mapping will give it a go myself a little bit at a time.
This is all dependent on if Surfside Moto actually have the part. They listed it with all the other products they have in stock, yet as someone posted earlier in this thread, 2Bros may not have released it yet (even tho they to have it listed on their website to "buy now"). So they may have sold me something they don't have, which would make me very upset. But I will hold fire till I find out for sure.
In my past experiance with canned tunes is it will never be as good as dyno tuning it. But on the other hand if two bros made the maps they obviously had a bike for R&D. My bike is at a powercommander tuning facality as we speak making maps for PC. They all do the homework.

You are absolutely correct. Website were selling something they didn't have. That said they apologized and offered to cancel order, which I did.
Just have to wait a couple more weeks.:(
Sportisi in Indonesia have already done a map etc for the powercommander.

See here. SPORTISI MOTORSPORT

maybe ask these guys if they are getting the cbr stuff..http://www.sportisimoto-usa.com/
No dyno of their pipe and fuel map.

I always view such things with a hint of suspicion. :D

Help a noob out here.
I'm assuming all figures are rear wheel HP/torque.
The blue being a stock bike.
What do the abbreviations for purple and red stand for.

Lastly, I'll have the purple thanks.;)
