    I don't believe that will work properly but best to check with Cobb on it. I've never tried it.

    I am honestly jealous of that log. I flatline in all of my Cobb maps except on the v301 Stage 2+ pump map.

    I am still baffled how I trapped 118-119mph while flatlining on the race map though. I can reproduce it all the time, but never on the old stage 2+ map...

    If you are bored borrow someone's G5 ISO and I can send you our flash map to test out. So far its been very promising.

    Which ECU type do you have? I am on IJE0S.

    Now I am curious about trying out the G5, or perhaps maybe getting protuned and see if that fixes it whenever I want to be on the E85 blend.

    same, IJE0S, although both Cobb and BMS swear up and down it's not a ROM-specific issue. Knowing the nature of the fix, it's can't work properly Cobb alone.

    @ChuckD05 had the flatline issue worse than I ever did and it seems it's mostly fixed, no matter if he shifts short or at redline.

    So you are saying that anyone who has been protuned on Cobb still experience the flatline issue?

    About 1.5 mph in the quarter mile and 0.3 sec in the 60-130 on flat ground. Keep in mind this issue is mainly on the 3-4 shift.

    Terry - Is this my log? By the way the car with the new flash and walbro pump are working great!!! Ive been filling up with the same e85 blend or a little more give or take and driving around on map 5 for now since its been cold outside and no need for more then the 17.5lbs of boost set on map 5. Map 7 is a beast for sure. But right now just enjoying the car now with no issues. Let me know if you have any tweaks you want me to try since I find it fun getting logs on my spare time and trying to get the car prepared for some 1/4 mile drag times in the Spring.

    I highly recommend the BMS flash with the G5 iso to anyone on the N54 platform..you wont be sorry

    Might be, I get a lot of logs so tend to lose track of them. Working on some flash tweaks but so far nothing solid yet. I'll let you guys know when we have something. Click here to enlarge

    What kind of pressure is normal when running an e50 mix? I know lpfp requested is 72psi, but in my logs I see actual wavering anywhere between 45-75psi or so. Currently on stock lpfp but the walbro will be installed soon.

    Dont believe that will work sir. There is a hard limit in ECU. Must wait for cobb to release new firmware Click here to enlarge

    Actual pressure should be close to 72psi. If you're seeing 45, i would definately replace.

    This is awesome Terry. Flatlining used to be a real headache.
