    E85 mix dyno results with Jb4

    I Posted this on another E85 thread but i guess that one turned into a trainwreck anyway 2008 335i Jb4 Dci
    starting runnin 25/75 E85/93 yesterday. did quite a few WOT in map 5 last night and today. had the car dyno'd on a mustang dynamometer in Florida 90+ degrees

    stock(map 0) 271HP/298TQ
    Map 5 302HP/369TQ
    Map 2 326HP/375TQ

    maybe map 5 still hasn't properly adjusted.. also I haven't updated to the newer map 5. I didn't log so I'm not sure the actual boost on each run.

    any thoughts?

    if the new Map 5 is where Its at for E85 mix and anyone can help me update in the palm beach/broward county area let me kno. I'll buy ya beer/gas or pay ya. thanks

    Get the new map 5. You need to do 3 3rd gear rips after resetting the map, so dyno that first. You should do much more power.

    Are you still running the old JB4 firmware? maybe you have the new with no E85 support, or the car did not adjust to it. Try doing some pulls before you take it to the dyno, and have it adjust.

    i have the older jb4 firmware. haven't updated it since I installed it in march. I did lots of pulls b4 the dyno but I've also seem some say it took up to a week to adjust on map 5 with the E85. but yes I definately need to update to the newer firmware. if any one can help me out PM me. im in south Florida. I have the cable but unfortunately did not route it when I did the install, so yea I'll pay someone with cash beer or gas of they can help me route the cable and update my firmware. I PM'd you BoostAddict.

    Just route the cable through the firewall. Updates are a big deal. You probably don't even have e85 support.


    The people who say it takes a week to adapt are wrong. It takes 2-3 pulls to get there BUT you have to reset the map when you fill up. You can do this by selecting map 1 and then going back to Map 5.

    so wait, you mean i would have to reset the map when i fill up, as in to compensate for potentially having a different ratio of E85/93?

    Would need logs to check the tuning out, but keep in mind any time you select map 5 it resets. It's really not meant for dyno testing. Map 2 or 7 is best for that with E85 in the tank.

    makes sense that Map 2 or 7 would be more consistent while dyno-ing..
    Terry, the newest updates for map 5 (keep in mind I'm running firmware from march) should be stronager with the E85 mix correct?
    once I get the cable routed and firmware updated, I'll figure out how to get logs and send some to you

    Without seeing the JB4 log from the dyno runs it's hard to say if you'll make more or less power with the new firmware. But I'd guess more.

    I do... It clears out the learned data. If you are running +/-10% probably not worth clearing. If you go from 91 only to a mix then definitely clear it. Like wise if you go from 50% to 0% you should clear also or you are going to pull a $#@! load of timing and be in the danger zone.

    what firmware are you running? Order a USB ASAP if you dont have one yet... You can temporarily run it under the hood wrap on A pillar than through the gap between your door and fender into your front seat for an easier entrance to the car with the USB...

    but routing through the firewall is the way to go...

    You should only reset the map if going from a heavy E85 mix down to 100% pump gas. Otherwise, just let it learn out the mixture change as normal.

    Thing is you don't want to run it through the firewall if you are under warranty. I have no problem running it through the door since the wire is long enough to reach the laptop sitting on the seat. Takes just a minute to hook it up from the get go.

    well, ive been updated.. i swear with E85 and the new map 5, I feel a more noticeable gain than when I went from stock to jb4 back in march. it's been raining a lot here but I've managed quite a few pulls and it's definately learned up. im way impressed.. if anyone ihasnt tried an E85/93 mix with the new map 5... all I have to say is wow. and I'm only running 25/75 E85/93. I'll be figuring out how to log some runs and I'll send them to you Terry as soon as the roads dry up. good news is I'll have proof of the gains bcuz I dyno'd last week on thee same E85 mix without the update, so I'll re dyno soon on the same dyno with the same mix and mods and the new update..

    im gonna go out on a limb and say 18 bcuz I got the jb4 in march and haven't changed anything other than updating the firmware the other day.
    mpg is showing around 20.5 avg and I drive pretty spirited, but I haven't reset that since running E85 mix. but I'll say you WILL notice your fuel gauge sinking lol

    If you plan to use heavier mixes of E85 (50%) you should get a G5 now while you can do the cheap upgrade. I did it and I haven't looked back.

    Completely agree. I love my G5!!!! It definitely feels stronger. Not to mention that the G5 board sets you up for controlling larger turbo upgrades in the future Click here to enlarge
    Now I can't completely say it was completely the G5, but my 1/4 mile improved also.

    Good luck

    Slightly off topic, but does the G5 board simply plug into the P-n-P harness for the standard JB4 board? I read through the first post in the G5 thread and that seems to be the case. My harness has the white connector.
