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.

Massive problems with timely shipping and delivery!!!
Color: Grey, Size: 8' Wide x 6'6" Tall
I have purchased three panels at $1300 plus each. The first two came very late, in one shipment; the third in a separate shipment. I have yet to receive the third, despite being present when shipping has twice said the business was closed. The first two were delivered almost a week late after numerous discussions (over four hours with Amazon support in online chat and phone) specifying there is NO WAY the business was closed as it is open 24/7. CAUTION. Further, the video is misleading. The panels are 70 pounds. A 5’2 athletic woman will most likely need assistance to balance and stabilize the panels. The magnetic buttons work IF you can get the panels aligned, which must be a two-person job for a petite individual due to the panel’s 8 foot height. Check reviews thoroughly for the stability feet which can be purchased separately; the recommended sets are plastic and not sturdy. Overall: BEWARE of shipping and delivery drama. Do not expect this product timely. Ensure two people are available if you are not tall. Recommend consideration for a different acoustic panel system. I will most likely be cancelling the panel I have not yet received. The expense is not worth the numerous issues. Good luck.

Lower Quality than Competitors
Color: Black, Size: 8' Wide x 30" Tall
Construction is different from the Wall I brought from Children's Factory. Would recommend going there for a higher quality product and to save some money.

Well made… for children?
Color: Black, Size: 8' Wide x 30" Tall
This review is for the 30” tall one. I’m honestly struggling to find a great use case for how short this is. I don’t have children or am associated with any institution where they may be some. I could see it being used for creating that type of sound barrier. The panel itself is very well made. Looks and feels like an air wall that you’d see in a convention center. I can absolutely tell there’s an acoustic absorption property to it. The whole thing unrolls quickly and is fast to deploy. As far as privacy goes, it’s kind of useless unless you are trying to wall in small children. I can’t really say the value is all here for this. Seems quite a bit more expensive than it’s worth.
