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

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.

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? Quote:

i never bother with the avg boost just what it hits peak consistently. Quote:
not sure how boost targets work in BM3. assuming its similar to stock.

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.

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 |

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.

Is the F90 tune going to have adjustable overrun levels?

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.
