Maybe the HPFP is on the way out and can't take the demands of the agressive maps. Have you had it replaced?

Your fuel is fine, your timing isn't dropping it's flatlining. Two different things.

What do your fuel trims look like? I don't see anything crazy in your timing, no drop outs or anything...

Ps- you're bogging. Shift earlier, say 6400 or so and make sure your foot is completely off throttle before you shift.

Can you post CAN DBW throttle? Looks like your fuel trims may be the problem here. I'd email shiv for help. Otherwise it looks fine.

I asked a few times what the expected whp of the proceed car was. I was told by Terry that the JB+ would cost me whp & went with the JB4...Stock it dynoed 314whp & on JB4 Map 2 365whp. Same dyno same settings.

On Drag times dyno page for BMW cars # 27, 28, 29, & 30 are all proceed cars & are showing 317, 315, 314 & 310 so its not impossiable a stock 335is can run with some of them.

Agree. He should be able to hold close to 10psi through the shift, and not go to 0 (at least on the first logs posted).

Understood. Were all trying to take a look for you to see if we notice anything. What is in your user adjustable settings? The downloaded values? I'm on 11-1 and mine are different than yours due to different mods. Can you post them? I have no experience with mobile1, only use shell 93 myself.

I dont know why that comes as a suprise. The same scenario can be had with me. I did 12.5 in a 1/4 mile with only 14 psi, FMIC and exhaust while you have FBO + Meth + non-RFT + 16-18PSI cars running the same numbers all over the place.

Its just simply put, the 335is DCT is nothing to recone with
Kinda agree here. Even a fast shift is no match for a DCT shift. And if you shift too late and let revs touch 6900rpm (and induce throttle closure), you will lose even more ground. The fact that you are pulling in 4th means that you are making power. The fact that you aren't pulling him earlier just means he isn't losing as much time on the shifts.

My suggestion is to shift a bit earlier and don't let revs go above 6800rpm (which means you will have to start your shift at ~6200 due to DBW throttle lag). With some effort, you will be able to keep DBW throttle blade from closing fully between gears. This will help your acceleration times greatly since you are now essentially discharging boost and having to spool the turbos back up between every gear. Hope that helps...

Agree on the shift point. Even with a DCT you still have a reaction time delay on the part of the driver when the shift lights come on till the paddle/stick gets moved.

I have mine set to 6250rpm & have never felt the “off the cliff” feeling you get when you shift too late & the power is pulled. I could raise it a bit, but based on my dyno sheets there is not much point.

at county line which is an 1/8th track i beat manual m3s loose to the DCT they get me on the second to third shift 335is is when overboost kicks in a formidable foe to a tune only 335i because of the gearing

The first step LC on this car raises a checker flag, if the driver intervenes the flag disappears. If the driver does not intervenes, other than steer, the checker flag stays for a limited time and the car auto shift at redline. But of course I am speaking form a dig perspective and not a roll here which will serve as correction by your reference
