The funny thing is, I haven't seen any m240i tuned or otherwise do better than 112 for trap speed. C&D had 111 for trap speed on a stock A8 m240i. I'm starting to think the piggyback boxes aren't doing much for these cars at the limit.

Mine feels much faster by seat of the pants measurement, but it seems that the torque management cut-in at WOT shifts is much more noticeable, and I'm wondering if that's negating the advantage from the extra boost, at least on the A8.

I feel the same exact way about my 6MT, I feel like it ran more responsive between shifts when stock (felt the same way about my JB4'ed 228i). Maybe I should do a stock run with JB4 off just to confirm this theory. But the car is definitely faster after JB4, I did runs on different maps against my friend's 335i and you could notice the difference.

Yes sir

Sport+ Mode only. Come to a stop in Sport+ press the clutch down and mat the gas. Pins it to 3k RPM, try dumping the clutch out of the hole first, then practice the slipping part of it if you don't like the slight bog of the clutch dropping. I think it's a bit of a placebo using DSC "off" and spinning the tires as it feels faster, but in the Sport+ mode, there's almost no wheelspin until full boost hit and it's still minimal (although I do have an LSD which aids in off-line grip)..

Edit: Hopefully works for you on the 228i...

Will give it a try! The 228i is sold however I only have the M240i now

I'll see if mine can next month when I finally take mine to the strip for an objective test of the mods.

Without a real ecu/transmission flash Id be suprised if it was better than high 11s

OP dont stress the times, this isn't a car you buy for crazy 1/4 mile times in any configuration, ours might be a bit faster than yours but it's not like these are 10 second cars.

I was doing consistent 13.7-13.8 runs with my 228i on stock 17'' runflats, so I NEED to be in the 12's atleast now with all this power

There are several 340i's over on n54tech trapping 114-117 with just JB4 or AA, catless DP and intake. And they're a bit heavier than the 240i, so the power's there.

I saw those posts, but as you said, they're running a catless DP and intake. I was talking about stock cars earlier and comparing how much advantage you get from just a chip with everything else being stock.

After my post above, another user on here posted a run with just a chip (Dinan Stage 1) and got 11.9 @ 113 with his xDrive 8A m240i. Sounds like he picked up .5 secs and 4 mph with just a chip over his best stock run at the same track, which is more the results I was looking for.

They're also running on some of the "wonder" tracks in the Northeast. Point being, one needs to consider the information and data before assuming all cars will go "such and such" with X mods.

I've been drag racing for decades and have learned there tracks that are faster than others for no reason, even considering density altitude conditions. I've seen it with my own cars and it's frustrating as hell. My cars were always .3 seconds and 3 mph faster in Houston than Kansas City. Same mods, same 60 foots, and worse conditions in Houston.

With that said, the N54, N55, and B58 cars are crazy impressive in terms of power unleashed from simple mods. Interestingly, they all seem to peter out around 400whp on the basic mods (piggyback/flash, DP, intercooler, splash ethanol). To go beyond around 400whp requires a lot more work, usually digging into the turbo(s) and fuel system. The B58 is proving to be the performer of the bunch with the least amount of money spent to achieve impressive results. Currently the N55 is pretty solid as well in terms of cash spent if you want big power for cheap as it's quite easy to change out the turbo for a Pure Stage 2 and get near 500whp and gain some more useable rpm. The B58 will soon be to that point and likely exceeding the N55 in that regard. Swapping turbos on an N54 is hilariously terrible and most big power N54s go single turbo.

I think that would be me


You are correct. I picked up a half second and about 4 MPH with just the Elite.


I?m very happy with those gains and the easy installation.

Maybe Dinan will have a Stage 2 come spring time as I?m done at the track this season.

If you have any questions feel free to PM me.

Dylan, is this for real or are you trolling? LOL

I'm testing this "Launch Control" you speak of after work for sure!

lmaoo, no my friend, this is legit! I found out accidentally when I was experimenting launching in different modes..

I've been hitting the tracks for decades as well. I've always heard Cecil and Rockingham were the "wonder tracks". Atco, Island and Englishtown get the benefit of running under the lights right until Thanksgiving before they close. Cool nights in uppers 30's-40's are great for mph, not so great for et on street tires. IME with these cars, 55-60 degrees is the sweet spot. Still warm enough for decent traction on PSS, but cool enough for reasonable IATs. 80+ ambient and they start to heat soak. BTW, a couple of those guys trapping 115-117 did so with temps in the 80's. Not sure on DA.

[cxp213]

I thought more people set PBs at Atco than elsewhere like Cecil or Englishtown in the NE?

Some tracks are downhill, and pictures and topography maps show this. I also think some may be slightly shorter. But yeah, I'd say setting a baseline at your home track and comparing to that (with conditions and track prep considered) would be the best.

Yep, those are most of the tracks. There's a really quick one up in Toronto too (name escapes me). I'm convinced the air at Cecil and Atco is 20% nitrous LOL Etown is pretty dang quick as well in the cooler months. I think all those tracks are quite quick largely because of their geographic location. Most of them are at near sea level and more importantly, weather fronts collide near coastal areas and create ultra high barometric pressures. Those pressures help cram more oxygen into the motor. Team that with the fact that many of those tracks allow people to run well into 40s (i.e., dense oxygen air) and the tracks will prep to compensate for the temps, most any car will run incredible times. Remember, these are the tracks where bonestock, street-tired 99 Z28s did 12.8s, 96 Cobras 13.4s, 01 Celica GTS 14.5, 09 WRX 12.9, C6 Z06s uppers 10s, etc. Those aren't really representative of the norm. I've run density altitude (DA) calcs when someone has posted amazing stock ET/mph at those tracks and often time, the DA is negative. Like, REALLY negative, often times in the -1,000 to -2,500 foot range. That's free HP and -2,500' DA is like getting a 10% power boost for free. People love to correct their times when the DA is crap, but they won't correct them when the conditions are stellar. The corrected times will increase ET/MPH quite substantially, usually like .3-.5 seconds and 2-4mph.

Yeah, I am jealous of those that get to run at those tracks, I admit it. I care because I want to make sense out of it all to understand what my cars are capable of and to also inform people that sometimes nutty ET/MPH is not the norm as DA can make a huge impact on ET/MPH. That's why the NHRA has a correction factor table afterall. Drag racing is a bit of a science and most don't understand it, especially those that run on Grudge nights.

I ran this at englishtown (terrible day but still). However I do hear that Atco is MUCH faster, but I cant justify the almost 2 hour drive.

Sorry, but I'm not . It's a legit feature, at least on the m235i...

https://flic.kr/p/Y9qMqD check that out

Whaaaat? I bet it has something to do with Euro Spec vs US spec. I work for BMW and have never heard of such a feature even for the m235i. If there is a way to activate this for M240i and someone knows that would be great!

I'm in Canada, but I've read of other users here who are aware and have used the feature, and fairly confident they were US owners.. A lot of us were skeptical as to the treatment on the clutch via LC, but it actually works really well, imo. In that video, I literally pegged the gas, and dropped the clutch. This was back in spring '17 and have done it a dozen times (at least) since then, no issues. But I'm not really trying to work a good 0-60, just having some fun is all.

I'll make a better video when I have a co-pilot, one of these days..

[Dylan86]

Here you go. No co pilot, though..
