    Well the battery was disconnected the entire time I was changing out the CAI. So it should be reset.

    You are probably fine then. I wouldn't worry about it.

    I just read where someone said to reset the throttle body to press the gas peddle to the floor slowly (3 seconds timing) and then release slowly (3 seconds timing) it and to do this 5 times.

    Well that's not how we do it, but I can't say whether or not that works.

    Maybe turn the keys on 3 times, flash the headlights 5 times, right blinker, left blinker, right right left and that will work. :rofl:

    No shit? I swear I was reading up on it prior to buying my tundra and found that there was a slew of issues supercharging the flex engines based on the ecu and flashing. Plus mounting? Welp, learn something new everyday. Regardless, I don't have flex so I don't even have to think about it.

    Off to find some cheap whores!

    Although I had the flex fuel engine I wouldn't run that stuff in it. Stick with 87

    First fill up today on the week old 2017 Platinum MBM.

    TRD CAI and TRD exhaust fitted half way through at approx 200 miles, so NO idea if it's better or worse for MPG, however it's not an issue as my wife has a Prius for around the city/grocery shopping, etc.

    I ended filling her with mid grade E10, I initially wanted 100% gas but the usual station was out, so hopped over to VP Racing Fuels a few blocks away, but all they had was 93 ethanol free at $3 a gallon, E10 at 89 was $2.28......plus is a TT grade.

    Averaged 13.6mpg for the first cycle, for those of you who are interested; mixed driving - city, interstate and highway...I have a heavy right foot at times, especially when next to a F-150 or Silverado at the lights, thats look to have been 'built', LOL......:devil:

    So, here I am - I was helping a friend out down here at one of our local tuning shops and he starts a spiel of E85 based tuning comparative to regular ol' gasoline. While he's a strong believer in performance outside of milage, others in the shop have written it off as "green" propaganda.

    I'm wondering this... Where does my tundra family stand on this? I had told multiple people to NOT get a FFV based on milage loss. But after hearing compelling "corn power" tuning stories my brain has been almost convinced of it's possibilities in the world of tuning, drag, and performance. Who's actually used it?

    I think it's unwise to convert a food source into fuel.

    And as I understand it, gasoline without ethanol added not only gives you more power but it burns cleaner too. So less emissions.

    It's not a food source. The distillers grain that is a by product is used for livestock feed and is actually better for the animal and easier to digest than plain corn .also the syrup that is a by product is also used for feed and can be used as an additive in fertilizer. There is no food loss with corn being used for fuel. That corn that is being used not used in human food production. There is also varieties of corn that can make a ethanol plant more efficient . The corn that would be grown for a direct food source is not plain field corn. And the distillers grain is also exported to other countries for animal feed.

    I have used E30 fuel in a 2014 Tahoe for the past 4 years with no problems. In older flex motors when we ran E85 in cold weather it could cause the motor to start a little harder. We have been using flex fuels in a fleet of around 75 tahoes since 2013 .we have had no issues with fuel. Wish I could say that about the rest of the vehicle

    well let's see; worse mpg, sucks up water, destroys old hoses, acts as a solvent on old fuel varnish in tanks, lines, etc thus clogging carbs/fuel injectors/filters....

    what's not to like???!!!

    We always fed our cattle with split corn and other quality grains along with the hay.Would never think about using used distillers grain that's used in giant corp feedlots. Anything that has to be heavily subsidized to be profitable is a huge red flag.

    We've been running E85 as the sole fuel source in our 2014 FRS for the past 3 years. It was not an FFV vehicle from the factory.

    With an intake, exhaust and E85 tune, we gained 50hp on a 200hp motor, and that's a 'safe' tune since I daily the FRS as well as use it at the race track.

    The hoses and hard parts of the FRS were already ethanol compliant, so there was no replacement of parts needed. This isn't true for all vehicles, especially older ones. Typically you should only run E85 on a vehicle that was designed from the factory to use it, or replace everything the fuel touches to bring it up to spec.

    We purposely bought the FFV Tundra with the intention of tuning it the way we did the FRS.

    E85 is 85% ethanol and 15% 108 octane fuel (if you're luck though, you typically get 55-65% ethanol). It has a cooler flame front so it resists knock at high rpm - this is why boosted applications can benefit so much from it. The E85 isn't necessarily 'more powerful' in its own right, but since it burns cooler, you can advance the fuck out of the timing without detonation.

    I get about 17 mpg on E and about 21 on Premium (required in the FRS). With the cost differential in my area for most of the year, it costs me about 10 cents per day to run E85 when all is said and done.


    Short story - E85 is awesome for almost free power when properly tuned.

    It's costing us taxpayers a hell of a lot of money subsidizing inefficient production. That needs to get factored into any equation. Way too many negatives offset any gains IMHO.

    No offense, but he's referencing a non-Toyota problem (he does say it affected some older toyotas but doesn't know about new ones). I get that it's kind of a black hole for a lot of people that either don't have experience with it, or had bad experiences early on. But unless someone can show me where a Toyota Tundra had that problem, it's not really relevant here.

    I'm also aware of the early issues with Tundra FFV - which were resolved, and in the overall scheme of things there was a lot of noise from a relatively small sample of cases.

    It was a hidden problem that took a lot of time, research, and money to find and resolve. It also seems odd that all reference to that document disappeared from the EPA's website. How many hidden issues still exist that are being glossed over, or flat out denied? Gasoline is a proven commodity, E-85 has enough issues to fuel suspicion for many years to come. When production, delivery, and usage are geared for strictly E-85 (or better yet, pure ethanol) thing will improve. Until then, E-85 is just a kludge looking for the next problem.

    I know no boat owner is including me. I suspect that the only ones that are fans are corn farmers, lobbyists for them and liberals who think it is doing something good for the climate.

    This is where I disagree. Hand over my heart I felt this way at first but there is a huge amount of people in the performance scene who swear by it. I kind of dismissed it for a while because of it's background. But there's a lot of compelling information that tends to disagree with it being just a climate propaganda. Which is absolutely interesting to me. While I wouldn't use it as my single fuel source for towing due to high compression, I'm starting to have my doubts as to it's value in the community (street machine community that is).
