    Ok guys. Same map, mods, conditions, etc. Added 1 gallon of E85 on top of 3/4 of a tank of 93. Let me know how they look experts! Thanks

    You still have timing drops mid pull, high 3ks...

    I'd say mix in E85 to achieve 30% ethanol content and let map 5 do its thing. but definitely add more E85.

    Your IATs get a the end of the pull, that's hurting your top end... but that will be solved soon Click here to enlarge

    1 gal E85 on top of 12 gal is 7% ethanol. Mix more.

    Thats alot of throttle closure in that second log.. But most people will say its normal. Im not a pro on throttle closure.
    Traction was fully off?

    Add another 2 gallons E85

    Keep a eye on your fuel trims dont want them to go over and stay over 50.

    I'm not an expert on JB4, but how do you tune out throttle closures with the JB4?

    Yes traction control was fully off. I would like to reduce throttle closures too but I don't know anything about how to. This is on map 1 too so I'm suprised I need to use this much e85 just to keep a solid log with 13psi. I thought this was the 91 octane map

    It's preset by the map. With the G4 on lower end maps we use the throttle more aggressively to trim boost than on higher maps. On the G5 we use the same function for all maps. Generally speaking if you are afraid of throttle trimming, which you shouldn't be, then you'll prefer the G5 isolated boost control scheme.

    Well I guess it's up to @E90Company

    Sounds good. I basically narrowed it down to ER, ETS, and HELIX. I would go for Helix in a second but I am worried about retaining the stock piping. Is this an issue?


    Also for both of you, I see you have pre-LCI E90's (same here). Does the actual FMIC grill opening have an impact on anything FMIC related? It seems to me to be very small compared to on the LCI and M-Sport bumpers?

    Thanks Terry. I was planning to order the G5 at 20k miles anyways, so now I can't wait Click here to enlarge

    No I didn't! Do your AA intercoolers come with replacement piping? You guys are local to me so that's even better

    Also just a general question. Does the size of the opening on the pre-LCI E90 bumper restrict flow to the FMIC at all?

    Oh great ! Both of our intercoolers (race/sport) come with replacement piping on the hot and cold side up to the charge pipe.

    I wouldn't worry about the bumper restricting the air flow to much.

    Perfect. I may hit you up so I can pickup a sport intercooler when I have the cash Click here to enlarge

    Quick question. What's the percent volume increase over stock on the sport FMIC?

    you have roughly 15-16% ethanol content, that's not enough to clean up the timing. E20 is the minimum I would run to clean up ignition timing at 13.5 psi (map 1).

    From my conservative testing for cleaning up timing, baseline 10degrees ramping up to 14.7degrees (with no meth):
    E20 is good for 14.5
    E30 is good for 15.5
    E40 is good for 16.5
    E50 is good for 17.5
    E60 is good for 18.5

    This is with a JB4 only. Anything after that, a flash is typically required.

    add 2 extra pounds when combined with meth.

    Wow! Thank you!

    Do you know what the size of our fuel tank is? Also are you factoring in the fact that gas contains 10% ethanol?

    Thanks!

    yes, that accounts for total ethanol in the gasoline.

    Latest firmware, and I believe 18ohm. I am going to be getting the G5 board in a week or two.

    Awesome. Do you have a log of this on Map 5 instead of Map 1? My Map 1 91 logs look like that, but on Map 5 its usually cleaner but I get the same boost. Just something I have noticed.

    No, I've never actually tried map 5 yet, but I guess I will have to. It seems to be the better map

    For sure wind 3rd gear out at WOT a couple times to 6500. Map 5 is a little less consistent, I will admit, but it is faster and once you do a couple full WOT pulls the drive ability gets much better.

    Autotuning doesn't learn until after 4700rpm and on my car it doesn't realize there is much more boost in the mix until it gets past 6200rpm. Thats pretty much the only time I rev it past 6,000... after that it has learned and will give full boost lower in the RPM range.
