Know your exact ethanol content in real-time with our new LED display or by using the BMS CANflex, Fuel-It! or JB4 mobile app on your smartphone or tablet.

This new rear mount ethanol sensor kit conveniently installs above the fuel pump, under the rear seat, providing ethanol mixture and low fuel pressure readings via CANbus to your ECU. It's compatible with both flash only tunes and JB4 tuning systems. Includes our new CANflex ethanol content analyzer (ECA) using the standard 0xEC CANbus ethanol format. Low fuel pressure is transmitted in the 3rd byte.

For those running a JB4, the new low fuel pressure signal provides an additional safety map trigger. If running port injection, low fuel pressure can also be incorporated into your port injection mapping ensuring consistent performance even in situations where low fuel pressure is dropping.

For flash only cars your tuner will finally be able to monitor your low fuel pressure to determine if there is sufficient pressure for your tuning needs. Compatible with JB4, MHD, BM3, and all tuning systems that use the standardized 0xEC CANbus ethanol format. We can also customize the CANbus commands if needed, just email us the details.

The kit features heavy-duty stainless braided fuel line, Burger Motorsports CNC machined fittings, and unlike other similar looking kits was designed to minimize restrictive bends and maximize fuel flow.

Note: If your EKP doesn't have the CANbus wires going to it, you will need to find the twisted pair of wires in the wire bundle next to the EKP as show below. The twisted pair of wires will be a red wire and a blue wire with a red stripe. Once you make your connections and power on the car, open the enclosure to verify the green light is blinking and communicating. If the light is solid green, that means you have power but do not have communications and have a bad connection or the wrong set of wires.

Great suit
Size: 12, Color: Mint Green, Size: 12, Color: Mint Green
Very nice suit. Love the material. My 11 year old is tall and slim- 5’3”, 80 lbs. I got a size 12 for the length. The jacket fit perfectly, the pants was good length and has elastic in the waist to adjust for size. Overall, it’s a good suit and I’d recommend it.

Nice Suit - Light Gray Color OF Suit IS Not A Solid Light Gray, It Has Linear Designs
Size: 12, Color: Light Grey, Size: 12, Color: Light Grey
I had purchased this polyester and linen blend suit for my son, in size 12Y for him in the color light gray. The color of the suit depicted in the advertisement arrived to be a bit different upon arrival. It's not a solid color light gray, it actually has small black liner lines dispersed all over the suit. The coat features a single button in the center, and there are two side pockets fairly decent sized. Unfortunately right above the pockets are red colored lineal horizontal lines. I don't think those lines are part of the coat's design, there definitely is some printing malfunction. It is hard to see in the pictures advertised, you can see it in the pictures and video I have posted clearly. The material of the suit is fairly acceptable, actually better than expected. The child can actually wear it multiple times for various occasions. The suit emits grace along with acceptable stitching in every apparel along with the bowtie. The suit did arrive in a slide bag all folded up, so there were a number of wrinkles especially on the coat, its as if it had lost its shape. I will definitely need to steam iron it before it will be worn. Just like the coat has pockets the tailored pants also have two side pockets, and belt loops in case need of belt if the pants are loose. I'm actually glad I had ordered two sizes up because compared to his current measurements the suit is big on, especially the pants waist and length. I had measured the suit myself and below are the measurements. Pants Waist - 15.25 Inches Pants Length - 35.75 Inches Pant's Inseam 25 Inches Coat's Length - 24.5 Inches Coat's Shoulders - About 14.5 Inches Coat's Sleeve Length - 22 Inches Coat's Chest - 15.5 Inches In addition to the suit, I also received a solid colored light gray, bowtie. The bowtie has an adjustable strap, so you can set the bowtie to your comfort in the collar. You can wear it along the suit or without it if needed to match with something and still manage to look a show topper!. The coat has nice shoulder padding therefore it sits across the shoulders nicely having it hold its shape and style. Overall it's not a bad purchase, suits like these always come in handy for a unexpected or expected events. I'm glad I had purchased this suit I'm sure it'll come to use one day.
