as far as i know these things run 20-21psi stock so +6 map puts you at 27-28psi?? that's wild. again i'm curious what these things can reliably take, we all have heard the hurt engine stories I def don't want to send it to the moon.

here is a log from 5th gear on E30 last night. i am at around 21psi of boost right now.
You said 10.0 to 10.1 so I was going off of that. The only other JB4 in that range is the Russian guy and I have never spoken to him so have no idea what he's running. Sorry, I misunderstood you. But, yea there is a good number of guys running up to 10.2 or so for sure!

I think 20/21 is a little higher than what they run stock. I feel like it's more like 19/20. When I'm running map6 at +6 my average psi ends up being about 25lbs. I'm also using MS109 when doing that with tons of data logging and adjustments before hand. I don't get the crazy good DA's that a lot of guys do so you shouldn't have to push it that far.

I know guys that run 10.2 with JB4 that are running e30 setups and only averaging 22/23lbs and others on race fuel that need 24lbs to get a 10.3. So much depends on other mods you have, air temp, humidity and overall DA. Not to mention getting a good launch.

Not sure that helped or answered your question but GL

OP and I leading the Development

Full DP's and All-Season Conti DWS06 275/35-20 all around tires and half tank of gas on this testing although I usually test on full tank.

First Attempt 10.27@136.41mph
Second Attempt 5 minutes later 10.21@137.71mph (better 60'ft)
Moving moving!!
What fuel were you running?

Very impressed with everyone’s results ! On a side note, humidity percentage in the 30f range isn’t good but isn’t a killer like at 80F due to the amount of water grains present. Cold air will not hold as much grains. That’s why DA uses humidity in the calculation.

Hammer down !

i was going by the info i found here on stock boost numbers... but i dont know if hes using MAP or Prethrottle Boost for that column.
https://f90.bimmerpost.com/forums/sh....php?t=1513840

yeah launching in 28-30 degree weather is tricky. plus i test at an intersection where we drag race so i'm launching over painted white lines. i'm onto trying my 3rd set of tires that finally work now and consistently does 1.62-1.63 60fts, but feels like that's the limit for these poor all season tires

im also considering do an intake.... it seems most of the faster cars have them, but it's tough to quantify if they are faster from intakes or extra boost.

Agreed, I have no clue if an intake on these cars makes a difference or not. At a minimum I would do drop ins. I'm guessing some intakes make even slow the airflow down.

Assuming intakes help on the F90 it's a wild guess as to which one is the best as everyone has something different and putting up good numbers..haha

Looking at those stock numbers that Xfire posted, they averaged 19.6 after taking away the shift which puts it into that 19/20 that I suggested.
I'm sure that's not the proper way to calculate it but at least i'm comparing apples to apples as that is how I compute my average.

Stock boost is tricky as the DME target is never the same, you can have DME target 16psi one day and 21psi the next (i've seen as high as 22psi personally). I'm sure you know this is why many running the JB4 prefer additive boost over absolute in these situations. Its very DA/weather dependent it seems too. 3 days ago my DME target in 4th and 5th was between 16-18psi for me, it seems thats all the DME thought it needed to reach its torque and load targets. lets say I hypothetically ran +5 and reached 4 psi of that target I was at 20-22psi and ran low 7s 60-130 remember hypothetically .

I think BM3 is great, had it on my F80. if someone knows how to setup a good map 6 on the JB4 and read logs (many dont) there wont be a huge difference if looking at only performance numbers on 93.

You and I live close, we could do a compare of the two on 93 maps if people only want to know the performance difference, BM3 has a lot more benefits than just all out numbers too.

Is BM3 using a static boost target? or it is using progressive boost based on achieving a load target?

yeah it seems like a few fast cars have the burger hot air intake , but it looks like it may work. i might give that a shot or the project gamma i was thinking about too.

i never bother with the avg boost just what it hits peak consistently.

my best on 93 stage 1 was 7.1 i think with all stock hardware. with downpipes car got a lot faster i think it will do 6.7-6.8 now on 93. for now I am on E30 gas/map until that is finished, then I will switch back to 93 and start on 93 stage 2 map. im always up for some good virtual racing in mexico.

not sure how boost targets work in BM3. assuming its similar to stock.

How bad were the stock Pirelli’s in 30-40F. I’m replacing mine on the TTS since they go away under 60f.

Bm3 platform is great and I don't see myself running anything else, it's super convenient and I love the fact that I can switch maps with my phone pretty quickly.

Every bimmer platform I get I will run it.. tbh bm3 kinda stopped me from going back to Audi in a weird way lol. For those that have been patiently waiting I know it's annoying but bare with them and you'll be happy when they finally deliver.

Those are some times you've got there, reading the data looks like a 0-100mph in around 5.5 seconds? Veyron territory.

Well done!

I know it's a little OT, but I'm considering moving up to the F90 from my F80 ZCP. Were you happy after going to the AT and more weight? Do you miss the F80 much?

Thanks for the write-up. The bm3 platform is new to me, so I appreciate the detailed results, screenshots of the interface, and general description. Looks powerful and a great idea. I tend to collect ecu files....this seems to make that a whole lot easier to do. The other features are nice as well.

edit: and car is moving. great stuff

they were terrible ... like wood. most of the time i couldnt even get it to launch using launch control in the cold. it would spin for split second and shut it down. if i did a burnout they worked sometimes but not others. the PS4s were better in the cold but still not nearly as good as these AS3+ my last 4 0-60s are 2.56 2.58 2.56 2.59 in 28-30 degree weather.

the dragy doesnt have that as a preset so there is no way to extrapolate the data after the fact. but i would guess mid high 5s

i had the F80 ZCP for 2 years and it was a good car, never had any issues with it. i do miss driving manual daily but i don't miss the F80 at all. M5 is better all around, it is more boaty in offramps if you have it in comfort mode but I dont find my self taking them any slower than i used to. m5 is faster, more comfortable, much nicer interior, engine sounds much better. M3 did look better and mre aggressive though.

I have the 10.17 run with JB4. The average boost for that run was 22.46psi, map 5. I had another run that was a 10.27 with avg boost of 19.55psi, map 2. My car is a non comp, runs around 15psi stock.

I had f80 gmt and bm3 stage 2... Can't compare the two cars, entirely different... f80 - was always on and ready to have tires slip, even going into 3rd... f90 is on an entirely different level... Can be sedated when you want it to be and then cracked out at the push of a button...

I do once in awhile miss rowing my own gears, which is why I find myself shifting using the shifter more often than not, lol...

I am simply amazed at the numbers that are possible with a "family sedan" such as this.

It seems like we are on the very edge of 9's. When this can be done reliably, depending on whether it is on race gas or E fuel, more supercars will be left in our wake.

Great results obviously. OP any particular reason why you decided on going with ER DPs as from other brands? Thanks

Price. I paid just over $1k for all 4 pipes on black friday deal. I didn't think the others were worth the premium to be honest.
