E85
What’s the correct way to flash my vehicle for E85 use. I’ve watched a few videos and read on it but it seems I’ve gotten mixed answers. And before I do this, I want to know exactly how.
So everything I’ve read says to wait for the empty light and go fill up. And that I need to wait for the fuel trim to be at around 20% before any hard driving. But the conflicting part is, Do I flash after I fill up, drive for 10 miles and wait for the fuel trim to be at 20% Or do I flash before I fill up? Drive 10 miles and wait for 20% Or do I fill up and drive for 10 miles and the fuel trim is at 20% and then flash Thanks in advance. |

I do have a tune with OFT so that helps and avoids having to be cycling the fuel levels. Honestly, i would get a tune over the flex fuel kit any day. You will feel the difference on stage 2 E85. |

Oh I have OFT. So a tune is not in question. I’ve just heard mixed feelings about running E85. So I am trying to gather as much data as I can before I make the switch.
And how much of a difference would I feel? I have Tomei UEL, catless, Remark exhaust, and I’m running a stage 2+ Tune with OFT. So if I switch to E85 and the OFT tune, will I notice the difference? |

Anyway I have tomei UELs and have ran e85 for around 8000km. I have OFT but am using Wayne Roms e85 time. I’ll be honest I didn’t notice a huge different over OFT uel petrol tune but that might be as a result of me taking it very easy the first 200kms of driving and I may have forgotten what it previously felt like. I’ve had no issues with it mechanically, car runs fine and doesn’t really feel that slow. I’m in cold weather right now and the car has never required more than 2 cranks to cold start. Still it only really pulls when you’re in 1st or 2nd. It still feels like the RPMs pause for a split second at 4K RPM. Also it’s likely just my tune running lean, but I noticed switching to e85 my exhaust sound changed slightly. Rumbled more and backfired more aggressively on petrol compared to e85 tune I haven’t done a 0-60/ 0-100 yet but I would estimate around 6 seconds |

This is why I asked. With the mods I have, I don’t think running E85 is going to give me enough of a difference that I will notice it. Maybe one day if any stations start to pop up in my neighborhood, but for now I’d have to drive 10 miles to fill up. And I don’t think the difference in hp would be enough for me to go out of my way just to get gas. I’ll stick to my original plan of going FI before next summer while I work on my last few mods. |

I had changed the pulley after all this and honestly, wasn't even worth it. E85 alone smokes all the other upgrades i have done. |
