We 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, with FREE shipping included anywhere in USA / Canada.

Our 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!

Our 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 our 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 Flex Fuel Plug and Play 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 and Play Kit:

5mins 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!
Fully reversible/removable and back to stock without a trace in 5 minutes
Custom 3-piece Aluminum-6061 Flex Fuel sensor adapter with built-in sensor bypass to allow for obstruction free fuel flow made to fit in the vehicle factory fuel hat area below the rear seat
All connecting points sealed with fuel safe Viton o-rings
Flex Fuel Sensor Adapter housing provides additional 1/8 NPT ports for optional Fuel Pressure sensor addition to vehicles without a factory one for BM3 CustomROM v2 support
CANBUS Enabled Ethanol Content Analyzer (ECA) that integrates with BM3 CustomROM for complete and seamless conversion of your BMW to FlexFuel for BM3 Flex Fuel enabled OTS MultiMaps and custom tunes with your BM3 tuner of choice
Power/CANBus 4-wire plug and play harness
100% Fully Plug and Play harness to the BMW Fuel Controller connectors (EKP3) on S55, N55 vehicles
Continental Flex Fuel sensor 3-wire harness
Custom Aluminum-6061 CANBus Enclosure for the BM3 ECA board
Custom Fuel Line by XRP, kink-free teflon braided line allowing plug and play with the OEM fuel hat and factory 5/16” fuel feed line. No cutting or new lines required.

PTF take their time before releasing new products, it shows in the quality

[n55david]

yeah, I need to get one of these

[ajromero]

Wow this looks awesome. Would flex fuel work on a BM3 stage 1 car?

nothing really at stage 1, bm3 never had a stage 1 e30 map or anything. just cleaning timing with no timing retard.

Bm3 does not have a stage 1 E30 but with the high octane from E85 and the flex-fuel kit, bm3 should be pushing more boost and timing

Love this! Need to stop working so damn much all the time haha soon soon!

it won't though. it will allow you to run up to e30ish because It will only do as much boost and timing as the stage 1 93 map allows. it doesn't just scale unlimited. it's still limited by stage 1 parameters. same with stage 2 etc.

I'm a bit confused by your response. You first say it will allow you to go up to 30ish power; then you say it'll only go up to stage 1 -93 limit.

If you are running, stage one multi-map with the flex-fuel kit. bm3 will automatically detect the Ethanol increase and will adjust timing and boost. It's significantly more timing and boost than a stage 1 93.

Going back to the question of Jungatron on whether there is a power increase with stage 1 93 vs. multip map stage 1 with fuel kit and E85; the answer is yes, bm3 will scale dozens of tuning tables (torque, load, boost, ignition timing, fueling) when it sees the increased ethanol mix.

I got my info confirmed by PTF directly.

I never said anything about power.

stage 1 is stage 1 regardless what level of E you can run. you can run up to about e30ish on stage 1 and that's it since you don't have the fuel pump for it. the stage one multimap will adjust within the limitations of the stage 1 maps. you don't suddenly get more boost or a crap load of timing just because you have the flex fuel setup. first off the stage one map is for a stock car.. so can you imagine what would happen if it just decided to let you run 15 degrees of timing with 20lbs of boost just because you have the flex fuel setup? it doesn't work that way for good reason. basically it will adjust timing between the levels of the maps for stage 1.. so whatever the 91acn map all the way to the 93 map and no further. it will NOT adjust boost since the stage 1 maps all target the same thing its just different timing and again.. you wouldn't want to run more without the supporting mods for it, that's what stage 2 is for and so on.

The best you can do without the multimap and flex-fuel kit is stage 1 , 93

with the multimap , and flex-fuel kit, you can go as much as your fuel delivery allows. that's a big difference in power (again this is coming from PTF directly)

Jungatron asked if there is more power to be gained over stage 1 93, I said yes. You said no. Then you went on to talk about the limits of the fueling system. But even with the limit , let's say E30, that's still a lot more power than stage 1 93.

The multi-map absolutely scales up timing and torque based on ethanol content. The 91 or 93 maps are the base maps on a multi-map tune.

The flex fuel sensor will add a blend factor to those base targets as E content increases. I suspect in the OTS multi-maps, the upper limits are at E30 numbers.

So yes, adding the flex fuel kit will certainly add more power based on your E mix. The beauty of it is not having to re-flash between E30 and 91 or 93 maps. The blend factor would just be slightly lower on torque on a stage 1 vs stage 2 base.

You're half right. The limits of the MM stage 1 parameters are the low limits, not the upper limit. The flex fuel tables have upper limits beyond the stage 1 (or 2) parameters.

The blend factor will do just that - blend the ratio between the lower and upper table limits based on the factor determined at the E-Content read by the sensor.

This is much different than putting E30 in a standard stage 1 OTS map. Doing that will just get the max out of a 93 or 91 tune. Doing it in a flex fuel tune will give you more power. Stage 1 MM vs Stage 2 MM will just limit the flex fuel torque tables lower (my assumption since I can't open an OTS map in the editor) - but timing will certainly be increased.

timing sure but not boost.

A simple way to answer this question is if I install the Flexfuel sensor and:

-flash the Stg 2 MM and go bn 93 pump gas and an E50 mix, what happens?
-flash the Stg 2+ MM and go bn 93 pump gas and an E50 mix, what happens?

I’m inclined to think I do not get Stg 2+ power on the Stg 2 MM, even with E50 and the Flexfuel sensor. And, I could break my car running 93 pump gas on the Stg 2 + MM, even with the Flexfuel sensor.

So, there’s no way to scale bn Stg 2 93 and Stg 2+ E50, even with the Flexfuel sensor bc the boost targets are different bn the Stg 2 & Stg 2+ MM’s.

Whereas, if someone runs the Stg 1 MM with a Flexfuel sensor, they can run 91 & E30 fuels and the MM will essentially scale bn Stg 1 91 and “Stg 1 E30” maps, even tho Stg 1 E30 isn’t available as an OTS map.

Am I right or wrong?

This is a particular question that only PTF would know.

In my opinion , if the ethanol mix is the same, the higher multi-map stage will make more power because it's assuming you have more mods on your car, so it'll push the car more.

you're more or less correct. boost isn't scalable but timing is. I'm under the impression it will only scale as high as the timing maps per map allows.

the problem here is.. stage 1 93 max timing is X.. you may not get X because of the limitations of your fuel so you get Y. if you add e85 to your fuel mix you now have the capability to get X. there is no magical timing map that gets you more.power running the flex fuel kit. it's no different than running the stage 1 93 map with e30 in your tank. the gains your seeing just you running the map to its full potential.

boost is dictated by the map you are running and timing is variable based on the set of maps in your multimap pack.

I think what guys are forgetting in this discussion is that right in the Bootmod3 Config, before a MultiMap tune is flashed, is the menu to choose which HPFP is installed in the car. Default is the OEM pump which on the N55 EWG is flow limited to about E30 in the tank. Please see attached photo.

If one of the other non-OEM fuel pumps is installed in the car, the tune config must be set for it. I'm not sure if the car will even start otherwise.

The BootMod3 MultiMap tune definitely knows what High Pressure Fuel Pump is installed in the car. So the tune may be set to limit its parameters based on the HPFP hardware installed.

If someone with an OEM HPFP puts full E85 in his tank, I doubt that the MultiMap tune will read E85 from the CANBus and give the engine settings as if it could handle it. I'm guessing that in that situation the tune's max settings will be for E30 in the tank.

If the MultiMap tune Config is set for the Dorch Stage1 HPFP then I'm guessing that the tune settings will handle E50 CANBus sensor fuel readings fine. But maybe the tune might be limited to that if the CANBus sees E85 in the tank. While a Dorch Stage2 set in the MultiMap Config would allow the tune to fully utilize the E85 fuel.

Note: Once the fuel in the tank gets up to E60/E70 a Low Pressure Fuel Pump upgrade is required to pump that volume of fuel.

Hope this helps!

It’d be nice if the MM’s are setup this way, but I have a feeling they’re not. I think the HPFP selection is simply so the car will run has no impact on the tune parameters.

So many open questions….

this.. it doesnt. you can 100% flash the 2+ map on a car qith the oem fuel pump. it will run and drive but simply won't be able to deliver the fuel needed at wot under load. the fuel maps are static, along with boost. the tune will ask for that set fuel and boost even if the car doesn't support it and it works the opposite way too. the tune doesn't care what you have for fuel pumps or e85 in the tank, it will only attempt to adjust timing based on the readings of the sensor and knock events or pre knock.
