Default E85 question

Can you run full e85 if you have the ff kit and the fuel pump? Yes I know you need a tune I'm just not wanting to do any blends, would rather just pump straight e85

I think the consensus is... Not until we get an upgraded hpfp. Some one smarter then me can chime in.

Thatís correct. The stock HPFP starts acting up above e60. Youíll have to run a blend to keep the HPFP lubricated

One tank probably wont hurt much but you cannot run it all the time. I would always switch between high and lower ethanol contents each time you fill up.

you will still need a tuner to remove the 70e+ or higher restriction

The whole point of a FF kit is to run a mix. If you want to run straight Ethanol, you will need some sort of ethanol conditioner or run reg pump gas every now and then.

**Please be aware that not all stations have FULL E85, some may be a E70-75 or winter blends which could be less.**

I think you have this backwards. Tuners are the one making the car throw CELs and limp mode past E70, that's not a stock setting considering the car doesnt take stock readings of ethanol content.

Be sure to talk with whoever your tuner is going to be and get their thoughts on ethanol content. I believe there are some reputable tuners who say e60 is the max they recommend.

Also, as wrxlaunch stated.... even though the pump may be labeled 'E-85', the actual ethanol content can vary wildly and you'll want some ability to test what is coming out (either with a flex fuel sensor/kit or you can purchase an ethanol tester kit pretty cheaply (under 20.00) from some places online.

Yes I would be testing to see what the actual E would be. And I have read about the E85 conditioner to help lubricate it so the pump doesn't fail but I just haven't seen anybody actually run it. I would be fine with a blend but it would just be so much easier to be able to pump straight E85

There are no stock settings for a FF kit... Its an aftermarket sensor that converts voltage to raw ethanol content %.
