    Please don't take my comments as bashing, that's not what i am trying to do, but rather highlight the key differences between your setup and the stock twins. I had a feeling you would struggle against a FBO stock twins car in your current setup. Looking at your graph, you are struggling to hit 300hp/tq, whereas a FBO E85 car is typically around 400whp/500wtq. Your car will surely wake up when you crank up the boost, if the trans holds together, but right now the average hp/tq over rev range is much lower than a maxed stock twins car.

    i guess I'm not seeing the same dyno as you? it's all good though this is on the lowest boost I can run.
    I'm above 300/300 from 4600 on and above 400/400 from 5700 on I need to re dyno anyway, the turbo was spooling was slower than it is now since I fix the fueling issue

    Something also worth noting in that race,

    fbo car: 1/4 tank gas 125lb driver

    st car: just topped off tank 240lb driver.

No need to swap DMEs, its just a VO number I think and you can do it with a free tool like NCSEXPERT or WinKFP. I doubt it'd have any issues provided you wired in an appropriate TCU to the transmission and gave it the basic signals it needs. I'm sure it'd require a bit of wiring and fiddling but I don't see this being the hard part. The hard part would probably be fitting it in my case...for a fab shop though, not really, just another day at the shop

    To code the vehicle to be a 6MT:

    Download SP-DATEN_E89_v48.1

    In the ISTA you can find the proper flash and ZUB # and flash with WinKFP.

    Change the VO with NCSExpert and add FA $2MA (DCT is $2TC) on the CAS and NFRM.

    Nice graph, everytime you switch gears you're already at 450whp so I don't see the FBO n54 give you that much run for your money. At the beggining of a roll, yae probably. Then from there, its catch up in one second and pass in the middle of third gear. The end.

    Is there a video of the race? I heard a different story of what happened.

    I haven't seen a video. I'm just going by what I see in the graph and what technically should happen if all things worked correctly etc. Heck I pulled on a FBO 135 with e70 mix and I was only at 415whp435wtq. This guy has over 100whp than me so I don't think it should be a problem for him to do the same as I did. It's cool too cause in the video between me and the 135 you see when I switch gears he starts creeping, then up top I just pull. Area under the curve does matter 100%.

    Do you know at what RPM N4 AT tranny lands after each shift? At shich RPM did you assume the shifts to happen? Anything wrong in the shift point RPMs could cause the discrepancy between your analysis and the real race that happened.

    As i would expect, your car is WAY lighter than a 135i.

    what did you hear? the FBo car had a 1/4 tank gas and only a 125lb driver. I just topped off and weigh 240lbs.

    we did a 40 roll and he got a little jump ahead and around 140Mph+ I started rolling by.

    for 15psi I'm not complaining lmao. that also was when I was still having slight fueling issues and a tranny communication issue that I since fixed we will till again lol

    This is the exact info that I heard also. He had more torque down low and was able to be ahead 40-140+ MPH.

    Turn up the boost, run with less fuel and let's see what will happen next time. Click here to enlarge

    At 40mph ur rpm at 4 from the dyno sheet it's just 200rwhp, fbo on stock turbo at same rpm and speed about 360rwhp, next time race him from 50 or 55 mph 2nd gear, u will pull hard on him.

    at which rpm did u shift? fftech single turbo holds full boost to 7000 rpm!

    I'll take an educated guess at around 5k rpm. I'm just stating a perfect condition scenario, of course it's not always going to be the same outcome. In general though, it makes sense.

    Yea I know, but I'm 3200 lbs with my and my buddy in the car vs the 135 maybe 3500 lbs. And I only have 415whp AK has over 100whp, so It should have been somewhere close to that. Still would be a good race to see on vid.

    For the first shifts it is well below that partly because AT tranny decides to shift quite early because the shift points are optimized for stock turbos. The actual shift points would explain why the actual average WHP under the curve when accelerating can be guestimated so differently.

    it took the same length of time or less than fftec with the first single or Vargas with his stage 3. it was a complete custom job, all I handed them was the car and a 6466 turbo. It didnt take long lol all that's left is settling on whatever boost gives me 480-500wtq

    There must be an RPM signal output from the DME to the mechantronic module in the trans. Intercept and tweak that signal and the trans should hold the gear longer. The question is, would the DME throw a code if it sees 7k+ RPM and no shift has occured? I've had my car hit the stock rev limiter and not shift before (I think the trans was still cold), but no CEL.

    Mechantronics talks via CAN to the DME. They talk coffee talk back and forth about RPM, torque values, shift points, temperature, etc.etc.etc.

    mechatronics also tells DME to retard timing during shifts to reduce power for a split second. I had a mechatronics unit actually make a 745 DIE when doing low rpm shifts due to it excessive retardation (both timing and literally lol) when it shifted!

    mechatronics also tells DME to retard timing during shifts to reduce power for a split second. I had a mechatronics unit actually make a 745 DIE when doing low rpm shifts due to it excessive retardation (both timing and literally lol) when it shifted!

    ok guys how bout this one.. how can I get the tranny to allow me to brake boost in first gear to leave in boost. I have the alpina flash maybe that changed something ? all I know is it won't allow me to rev higher than ~2K rpm with the brake applied in 1rst. lol. I can't even do a burnout
