WHAT IS FLEX FUEL?

Flex fuel is the ability to fill your 2020+ BMW S1000RR with either pump gas (91/93 octane or E85 without having to make any tuning changes. Fill your tank with either fuel and your bike will self-adjust to optimize performance for that fuel. This isn’t a new technology by any means and quite a few cars come with Flex Fuel from the factory. This, however, is the first time it’s ever been offered for a motorcycle with tuning only.

FLEX FUEL BENEFITS

• No tuning changes needed to run either gas. One file does it all.
• E85 can make more power than pump gas but a little less than VP MR12 with the main benefits being easily accessible, cleaner running and less messy/needy than MR12, all while being available at many local gas stations.
• It’s cheap as well! MR12 costs about $160 USD for 5 gallons, E85 is about $2 USD per gallon (depending on location).
• E85 will not foul your spark plugs like a leaded race fuel does after long term usage.
• E85 will not harm your catalytic converter or O2 sensors like a leaded race fuel will after long term usage.

HOW DOES FLEX FUEL WORK?

Our Stage 2 and incoming Stage 3 performance upgrades utilize the factory wideband sensors to adjust the fuel trims. FTCL (full-time closed loop) means your motorcycle already has a fuel map that it will use when you’re riding AND has a lambda target it’s constantly adjusting to hit. When you change fuels from pump gas to E85, the bike will require more fuel (about 30% more with E85). Our FTCL calibration will see the bike needs more fuel and adjust to hit a safe target. The S1000RR already does this from the factory but only for a small percent of time during cruising (not WOT) and only for pump gas. We adjust the software to make sure the closed loop system is on at all times and specifically adjust for E85 under certain conditions and variables.

WHAT YOU NEED BEFORE PURCHASE

Because Flex Fuel requires FTCL. Before purchase you’ll either need to have our Stage 2 or higher mapping. No hardware is required! Just a software update. We have rigorously tested this mapping since mid-2019 on our own shop bikes and a select few customer bikes. This mapping has been successfully tested in 210+MPH drag racing, roll racing, casual riding, on circuit track riding.. and the owners love it. We have nothing but great things to say about this mapping and all of our beta testers strongly agree.

DYNO PROVEN

RED = 205whp / 88wtq (93 octane pump gas, full bolt-ons, Stage 2 mapping)
BLUE = 208whp / 90wtq (E30 MIXED E85 pump gas 30%, full bolt-ons, Stage 2 mapping)
GREEN = 213whp / 92wtq (Straight E85 pump gas 100%, full bolt-ons, Stage 2 mapping)

You can see the E85 dyno making fuel from the mid-range all the way to the limiter over pump gas.

TOTAL GAINS OVER PUMP GAS = 8whp / 4wtq

**Pump gas testing performed with optimal dyno conditions utilizing 93 octane pump, E30 mixed ethanol, and E85 ethanol gas. Usage of a lower octane will yield lower overall power.**

*IMPORTANT*

Consider the following before your purchase

• E85 isn’t available everywhere. If you’re not sure if you have E85 locally, CHECK THIS WEBSITE.
• E85 burns 30% more fuel than pump gas. Keep this in mind when going for a ride as your gas mileage will be 30% less than pump gas.
• Cold starts in 40 degrees Fahrenheit or colder may be harder for the engine to turn over (not harmful and once started and warm it is fine).
• Common sense, but we recommend you do not let E85 sit in your tank with no use for long periods, (more than one month) as the fuel doesn’t last as long as regular pump gas. Alcohol based fuels, like leaded fuels, can dry rubber and seals and stick injectors tips if left sitting for months on end with no use, do not let a bike sit with ethanol or race gas in it for a period of time.
• Only fill your tank with E85 or pump gas when the gas light comes on. Mixing half and half will provide lower performance.
• Make sure your local E85 gas station has good ethanol content (some stations have lower quality E85). Ethanol can vary (between 50-85%). We recommend you test yours before purchase. TEST KIT.
• Lower ethanol content in your E85 means less performance.
• After switching fuels we recommend you gently ride your bike for about 5 minutes while your motorcycle adjusts to new fuel.
