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.

If you're running E85 or ethanol mixes in your B58, B48, B46, or B38 equipped BMW, you need this kit!

As many of you know the BMW motors can be very picky about how much ethanol you run to achieve peak performance but not run lean. Consequently, we have put together a kit enabling you to easily install an ethanol sensor with no permanent modifications needed. You will simply remove your low pressure fuel line in the engine bay and plug in our kit. It's a complete plug-in solution that utilizes our Bluetooth app to monitor your ethanol content. When you are ready to return to stock, you will simply remove the kit and re-install the stock fuel line.

All of our complete kits include the following:

  • Genuine Continental® ethanol sensor
  • One stainless steel braided fuel line with black nylon sheathing to protect your other engine bay components
  • Proprietary custom billet fitting for plug and play OEM integration
  • One custom wiring harness
  • One tube of SuperLube® for hose adapter install

Complete Kit with BMS CANbus ECA includes:

  • Our new CANflex LED ECA to display current ethanol content
  • Legacy 5V output for JB4 integration
  • Universal CANbus harness for use with future flash tuning integration

Honda product and quality.
Do NOT understand why my lawnmower with a Honda engine did not come with a Honda carburetor. Replaced with this Honda carburetor and starts easily. The other carb only lasted 1.5 years.

Worked but not well made. If you need 24 hour turnaround only option.
The housing is 95% identical. Float valve seat is smaller than mercury/quicksilver. The carb I received was stuck wide open. Had to completely pull it apart to fix the throttle. Then the choke didn’t work correctly. So I ended up putting this housing on with all my old mercury carb parts inside. All I needed was a new float valve but they are back ordered indefinitely. So this worked because the housing is correct but that’s about it. Internals were plastic. Not metal. Jury is still out on the jet size. I’ll update if it floods the motor at speed. Seems to be running very rich. If you’re looking for easy, I’d buy the quicksilver that’s tuned for the motor already. The carb I received idled too fast and even if the throttle wasn’t stuck open it wouldn’t have run well with a racing choke (screams air leak because of poor quality)

Throttle pin defective
This carb fits my tohatsu 3.5 hp but the throttle pin is defective. The only way to regulate it running wide open is to choke it out.
