What is a JB4?

The JB4 is a plug & play tune available for turbocharged vehicles. The JB4 tuner installs between your car's sensors and its DME/ECU (computer) and manipulates vehicle performance through these connections making your vehicle much faster. While it's not the only tuning system that operates this way, the JB4 separates itself from the competition with much more advanced connection points and processing, including CANbus, fuel & spark control, Bluetooth to your smartphone, and a variety of innovative and advanced features not possible with any other system. BMS regularly publishes free mapping and firmware updates adding performance and features as ongoing development allows. In addition, the JB4 system is not VIN-locked to your vehicle and can quickly be removed and swapped between cars or resold at a later time. Often imitated but never duplicated the JB4 has been the gold standard in plug and play turbocharged performance tuning for over a decade and is sold in over 67 countries worldwide.

Is the JB4 a real tune?

Yes the JB4 is a real tune. By tapping into specific sensors and CANbus for real time vehicle data the JB4 is able to alter your boost, timing, AFR, and/or fuel trims, to a similar degree an ECU reflash would, but without the vehicle ever knowing its been tuned. The result is safe, smooth, and significant power and torque gains while retaining your factory safety systems and without having to unlock/flag your ECU.

Polarity
Color: 6500K White, Size: 1Roll x 16.4ft, Color: 6500K White, Size: 1Roll x 16.4ft
I've been looking into various kits and components but this one seemed to fit my needs perfectly - all components included and the flexibility to cut strips (up to 6) to the lengths I needed. Its also very thin and needs no other mounting hardware, channels, diffusers, screws, etc. No instructions - but everything only fits together one way except which end of the LED strip to connect to (polarity). For my reel, it was towards the center of the reel and not the freed end - which meant I had to cut a piece off and connect the end that was just cut. Insert the cut end into the connect after peeling off a bit of the blue tape. You can also peel off a little bit of the white tape beneath that to expose the copper contacts - but the connector contacts can pierce that layer if you don't want to peel off the white layer also. (Don't peel it all off, just enough to to fit into the connector.) Insert the end, press down the hinged part until it clicks or is otherwise all the way clamped - don't need tools, just your fingers squeezing it is enough. Test the assembly by plugging it into the power supply. You can also connect the remote - a blue LED on the power supply tells you whether its on or off. Once I figured out which end to connect to, everything was quite straightforward. I installed my 6 strips in my small pantry - one for each shelf - and routed all the wires to one side, mostly hidden. I mounted the remote on the pantry door - it can sense through the door - which is not very thick - as well as just tapping it once the door is open. The remote can be touchless - just wave your hand near it - but it seems to also sense tapping from some objects. Holding down on the remote activates dimming - it will cycle through brightness and stop when you release. Other than that, its as simple as I had hoped and took me about an hour to install (I expect my next install will be 30 mins). I am planning to order more kits for other closets, kitchen, etc.

UPDATED: Replacement works great
Color: 3000K Warm, Size: 1Roll x 16.4ft
FINAL UPDATE: Seller shipped new power unit and it works great now. The lights are really great and super easy to cut to size and use. UPDATE 1: Seller got in touch and is sending replacement power unit. Will update again once it arrives. I do really like the look of these and they did wonders for a dark park of my closet that has built-ins. ORIGINAL: Lights stopped working after about 6 weeks (beyond the 30 day return policy). Seems like the control unit died. Haven’t found any feasible way to contact seller or manufacturer. Will update review if anything changes.

Light it up!
Color: 3000K Warm, Size: 2Roll x 16.4ft, Color: 3000K Warm, Size: 2Roll x 16.4ft
I am very happy with these. They are easy to use. The only reason I am not giving a five star review is because the instructions and assembly weren’t the easiest. At first we could not get them to work. After looking through the reviews, one man told us that the -\+ were backwards and we tried what he suggested and they worked. I do suggest that because there are two light reels there should be two connecter boxes as well. We had to purchase two packages. Overall, We are satisfied with our purchase.

Quality just isn’t there
Color: 3000K Warm, Size: 2Roll x 16.4ft
Was very excited to receive this product because I had difficulty lighting op these LED strip lights, this looks like a package that had everything that I needed. First off, the strip lights themselves are very thin with wise and would look funny on my project, the adhesive backing did not stick at all once removed The touch sensor works great for about 10 minutes and then completely died, overall not impressed with the quality of this product, sending back

Excellent Cabinet Lights!
Color: 3000K Warm, Size: 1Roll x 16.4ft
Great cabinet lights. Easy to install and connect. The touch less control is handy and works well to dim and turn the lights on and off. Been using them for half a year now. No complaints.
