Converting my BMW E90 M3 to Flex Fuel E85 DIY Guide APE Kit 

M3 0-100 MPH with E85 kit installed: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-lqlY_VqAdxo.html

One thing for those are struggling on that main fuel line disconnect there a white ring piece he doesn’t have that needs to removed first before u can squeeze the line and remove it

Great, detailed content.

Thinking about getting this for my m3. What do you think is the best way to do e85. I am NA so would I have to upgrade injectors? Is the most efficient way to run this kit, bpm flex fuel tune with stock injectors?

How was out after a while? Did it damage anything? Was there power gain, difference in acceleration you can feel from pedal?

Hey sal, recently bought an x pipe in december from you. I got a tune from chaos calibration, i didnt include any option for e85 at the time. Would i be able to add this without needing to tune again or do you know if its better to tune again for better performance/reliability? It would be the last thing needed for NA gains

How did you like the kit? Did you feel a noticeable difference? I’m FBO rn, thinking of running this next. Thank you!

Any cons to running E85 as far the motor goes?

You’ve been running e85 for a while, what are your thoughts long term ? Thanks

How do you like the E85 kit so far?

Did you have to change out to bigger injectors and fuel pumps too? Or is the stock fuel system is just enough to run e85? On this m3?

Can I install the flex fuel sensor and not run e and drive the car around on 93oct until I tune for e85?

I heard a lot of pros for this but never a con. Is there one?

Hey i have an e92m3 and have an alpine motorsports tune on 91 octane will I need to tune to be used with e85 or will it adapt to the fuel thar in the car?

hi sal im running full e85 on my e92 m3 supercharged upgraded fuel pump and 613cc injectors car pulls like a train made 460rwkw only issue is cold start ctakes 30 mins to start once warm no issue anytips tried all types of tuning maybe should run flex and e50 really cold here atm

Why didn’t you upgrade to 1050x injectors ?

does the ethanol sensor or flexfuel ecu need power? I didn't see that part in the video.

will the e85 corrode at the original fuel lines over time ?

So it's just plug and play no canister to put fuels

Do you need a tune to run it?

did you tune it?

what is flex fuel ?

Don't follow this guy he's not telling you everything. Buy the kit and save 2 grand and pay a professional BMW tuner to get it done as you'll need a tune most importantly after the kit is installed anyways.
