    E85 50/50 REMIX!

    REMIX:

    So my fellow car enthusiasts, I went back in the lab with BrenTuning. He found some room for improvement on his COBB protune.
    The car IS insanely fast! I could only imagine what it will be like with a Vargas Stage2 turbo kit.
    Anyways, with my KolaMotorsport differential, the car puts the power down, but it's still looking for traction! I do need some new rubber though.
    One thing that I was bugging me with this car was the throttle response. When I would drive over bumps with my foot slightly resting on the gas pedal, bump would make my foot tap the gas and the car would jerk.
    Well Brendan made the throttle a lot smoother and linear and I love it!
    The new numbers are nucking futs, 473whp/542wtq on stock turbos!

    Since the original map was made on much older Cobb firmware - He made an all new map and pushed the factory boost solenoids with the cobb software and WGDC tables resulting in additional power. This map was a bit more aggressive on fueling and boost. We also found a slightly more potent E85 pump. Once the power went up and load targets according to Bren, the stock throttle map was really annoying and the linear throttle maps to be really flat. We found a happy medium that makes the car alot more driveable at this aggressive power level. Boost is 19.4.

    Looks like I need a Vargas Stage 2 Turbo upgrade to hold that power on the top end.

    Great numbers @UsualSuspect . Any plans to take the car to a Dynojet and dyno in STD? As you know dynos can have large variances as portrayed very nicely recently by @VNeBLOB42 and his runs on a Dyno Dynamics first followed by a Dynojet where power on the same octane/tune/mods/weather varied by as much as 48-50whp between them. Just sayin'

    I hate to be a skeptic but what was the baseline for those runs? I agree that something doesn't add up.

    I don't think that anything is "off" or that it doesn't "add up" at all to be honest. It's just a different type of dyno at the end of the day. It'd sure be nice to see Dynojet STD or Mustang numbers, OR, who really cares about peak dyno numbers Click here to enlarge hit the track and I'm sure you're already having tons of fun with it compared to OTS maps. The car has been customized to OP's liking and that's all that really matters in the end.

    Dynapack's are generally just under dynojet numbers, so unless something has been fiddled with, i think something is amiss. On another note, PRS said they tuned a 135 on E85 to 450whp 500+wtq on a mustang dyno - stock turbos the other day, so who the hell knows lol. And no, i dont have dyno numbers, vids, or any further information so its very speculative at this point.

    Everything adds up, different dynos read differently.

    Lets see a baseline or a 3rd gear WOT log. The stock turbos cannot flow enough volume to actually produce those numbers at the wheels in real life. Good gain over previous run though. 23whp more is nothing to scoff at.

    @UsualSuspect how about some 3rd or 4th gear datalogs? I'd love to see what your boost curve looks like along with WGDC, load, timing etc...

    I've never seen Brentuning numbers that weren't substantialy higher than what everyone else is seeing, I just assume it to be a high reading dyno.

    Nice Numbers! A run on the same Dyno @ MAP 0 would be nice to see. Any chance or future plans to do so? I would say Delta numbers are just as important as peak numbers. As dzenno said, I had nearly 50 whp difference between a Dyno Dynamics and a 224 DynoJet on STD Correction Factor. I am very curious on how it would read on a DynoJet.


    @dzenno@ProTUNING Freaks thanks for the recognition!

    We have a baseline of 295whp stg0 fully bolted for this car same day. 370whp cobb s2+ 4.02. Go from there.

    STD is this new BMW dynojet thing to inflate numbers IMO not the way to dyno. SAE.

    You're crossing vendor lines.

    I've been using the same dyno since I bought the car. So what I've always been concerned with, is the gains the car makes.

    Sure SAE will give you a more realistic numbers, but most of the vendor community uses STD, so its a good way to compare peak numbers. Besides, IMO its all about the Delta's; that's a more universal comparison. Between my Dyno Dynamics CF SAE 130whp delta (baseline; fully stock) and DynoJet CF STD 124whp delta (baseline; FMIC, DCI, E50 & COBB MAP 0). It's safe to say I have added about ~125 whp to the car from stock, more or less of saying "my car has 400+ whp"
