    Ethanol update...

    I'm at E45 now, from E30 before.

    FRP still hitting commanded pressure at 2200 no problem.

    Any chance you'd release your ethanol tune to the community so we could try (at our own risk of course), or are you planning on monetizing it at some point?

    That's a great question. I might do something like what I did/do with the Mitsubshi community:

    http://forums.evolutionm.net/09-ral.../443880-2009-lancer-ralliart-gst-basemap.html

    Want to get more miles and better understanding of the ECU first though. Also would need to look into the logistics and legality of it as well.

    That is *exactly* what I was hoping for. Currently all the tuning for the FiST is pretty closed off. I haven't seen even a single custom tune posted anywhere yet other than the OTS Cobb tunes.

    I currently have zero car tuning experience, but I'm getting a handle on how the ecoboost ECU works and I've done a lot of reading on general tuning theory, I was hoping that the FiST would be my learning platform (factory wideband ftw), but everyone who is doing tuning for Ecoboost says it's FAR more complex than any other vehicle they've ever tuned (including you :) ), which has been putting a damper on my willingness to start experimenting.

    you wanna rent a dyno. start increasing the ethanol content and doing runs while watching stoic, and pressure (is that what you watch. do they have something like percentage used, sorta like a non DI motor's injector percentage?)

    i really want to know if you can add a slightly bigger turbo and run e85 without screwing with the fueling system.

    I'm watching all those things. I've been tuning on Ethanol for over 6 years now on a bunch of different cars, setups, situations, etc.

    DI has Injector PW (I posted the current PW values earlier in this thread) but what I'm really keeping an eye on is both the HPFP and LPFP duty cycle and pressure to make sure they are keeping up with the increased volume demands.

    Stoich (or whatever you set in the target in this ECU) will always be reached up until it runs out of +30/-30 fuel trims on this ECU. I've been tweaking the Global Scaler with each % of Ethanol change as well so they trims don't have to sway too much as Ethanol increases.

    As far as you eluding to using a dyno to find MBT, I certainly agree but I'm not currently shooting for anything close to MBT. Currently seeing what % of Ethanol I can get away with the stock fuel system, then I will do the real fine tuning.

    I have no update on the car today so I figured I would just post this photo of it in in my garage with some parts ready to be installed:

    I kid, that's a Fiesta R5, and it's not mine, nor is the garage.

    Still at E45, here is a snap of a log from this morning. HPFP still keeping up no problem.

    Ok here is where I'm at currently with E45. I think I'm going to leave it like this for a bit and beat on it and log a bunch to make sure every thing is ok. I could probably run more timing out the top but going to keep it where it is for now.

    Really happy with the power gains for a 100% stock Fiesta ST with just E45 and tuning. Pretty darn awesome, especially with the dinky turbo it has.

    +35whp / +75wtq peak gains

    That is seriously impressive. 285 ft-lbs to the wheels is absolute insanity for a 1.6L engine (and a stock one at that!). My old F-250 with a 7.5L V8 put down 375 ft-lbs to the wheels with 4.6 times more displacement.

    That is pretty much the same gains as cobbs stage 3! That really does blow my mind what tuning with e blend can do. Any chance you might want to sell your tunes?

    You know there are a bunch of us ready to pay for this. you should be compensated for your time and knowledge. Even if you don't want to formalize it, give us a paypal address so we can throw something your way. This is way too much tease, please share it.

    I would have to become a Cobb Protuner (again) to sell Cobb maps for profit and I'm not in this to make money.

    I will continue to share my findings for sure. I think there isn't an issue with sharing maps either if people are curious to see them. You would need to have Accesstuner Race though.

    I have the ATR and would LOVE to get a handle on this tuning thing to understand how my car works. And a peek at your work. And I know once i recieve the map in my mail box it is all on me no implied guarantees or promises as to what the tune will do for me or to me as there are SO many variables in fuels and drivers ...
    Thanks

    I was trying to think of a phrase to adequately express what I felt when I first saw the pic of razor's garaged Fiesta...you said it perfectly!

    Make sure you read what I posted below the photo. ;)

    Does anyone else notice the gear this log was taken in? Numbers will be elevated compared to a real dyno done in 4th (1 to 1 ratio)
