Product Information

Pro Tuning Freaks are proud to bring out this truly awesome product that makes getting the required Flex Fuel hardware on your BMW with incredible ease and minimal effort, in your own driveway.

The bootmod3 FlexFuel Kit is entirely plug and play with the factory vehicle harness. No cutting, splicing or de-pinning OEM wiring/connectors. It installs in 5 minutes and can be removed without a trace on the car in even less time!

The team used SolidWorks to design a Flow Optimized Flex Fuel Sensor Adapter (FFSA) to ensure fuel flow is unobstructed and with no added pressure drop at full fuel pump flow from the fuel tank to your motor when the BM3 FlexFuel Kit is installed. This is important when pushing the factory fuel system with all the power Ethanol can provide over petrol!

Flex fuel sensor housing is designed to neatly install into the factory BMW fuel hat location. It features top of the line fuel hose manufactured and pressure tested in house by industry leaders in fuel line components, XRP.

Flex Fuel Sensor Adapter also contains two 1/8 NPT ports that allow installation of an auxiliary Fuel Pressure sensor for vehicles that don’t come with an OEM one from the factory for future use. Depending on fitment, either port can be used.

Install the BM3 FlexFuel Kit and flash your flex fuel enabled BM3 OTS MultiMap or Custom Map in minutes and you’re off to the races never worrying about alcohol/petrol blend % in your fuel tank. It does not get better or easier than this!

BM3 FlexFuel 'Plug & Play' Kit:

  • 5 mins to install at home as opposed to hours at a shop with car up on lift fabricating/cutting into factory fuel lines and splicing/cutting/pinning into OEM electrical.
  • 4+ hours in time/cost savings to get going on Flex Fuel as compared to most other kits that require making custom fuel lines, fittings and custom wiring!

One of (if not THE most) professional outfits I’ve dealt with - in the auto industry or otherwise. Needless to say, all work was carried out as promised and to an impeccable standard. Thank you Sean and team - you’ve renewed my faith in the auto business!

Fantastic customer service from the team at Southern BM. Expertly repaired my 2011 323i and did so without the attitude and excessive cost of a dealer. Thank you and I will be back for all future servicing.

First time at Southern BM today and it won't be my last. Efficient and quality service as I'd expected at a much more reasonable price than a BMW Dealer. The only downside, you'll drop your car off and will end up drooling over the m3s and m4s out front!

Excellent service at reasonable prices. The shop is very nice too, you almost feel like you're at BMW.
