Jesus, does anyone search anything anymore. As said before, fuel lines are E85 compatible. You can run up to E25-30 on the stock fuel pump.

Been running the Stage 2 E30 map just fine on stock HPFP.

Yeah I don't really like the idea of running e30 map on the stock pump. If the rail pressure goes down the cylinder might get dry lol then you are f*****d

Ah, gotcha. The importance of logging and "every car is different" is understated. I did an E32ish mix, and mine drops to 2400psi for 400rpm (2700 - 3100). Before and after that range, rail pressure is good. I can live with the 400psi dip.

Really? Alex from Mission Performance saw dips in rail pressure with just 1 gallon of E on car on the stock pump. Was noticeable in driving too...felt like timing being pulled 🤷

Not questioning your findings mate but where did you read running E85 with stock fuel lines are compatible for the long term ?
On my official BMW fuel cap label it says maximum E10. As far as I read engines built for running high Ethanol content are using different materials on the whole fuel system as Ethanol is very a corrosive fuel. I think at this point nobody knows what long term damage could Ethanol cause.

Running e it’s a good idea to test the base fuel. There seems to be massive swings between stations so this could impact on the likelihood of the HPFP crashing.
Have you run any logs since putting it in. Generally e seems to clean up timing at the right amounts. |

This x10000. I ALWAYS test the "E85" every time I fill up (then do matrix reduced row echelon form to tell me how much ethanol and 91 to put in). It's an extra 3-5 minute hassle to ensure I'm getting as close to a perfect mixture as possible. And my logs look decent because of it.

I ran 40% E85 with meth. Your fuel lines will be fine. Yes indeed the car runs way better with even a small splash of ethanol.
