Don't know but looks like a bearing issue to me too.

Turns out this customer was racing a lot on map3 at 7000'+ DA in CO. So likely is impeller speed related. Higher elevation guys may want to stay on map2 until we know if it's a trend or isolated case.

We've done a few, logs looked fine. Only seen map1 and map2 so far though. Not looked at race gas map3 yet.

Seriously, 107 in the 1/8th? This thing has to be smoking 720S's. Seriously insane! Just checked, looks like a Stock 720S is doing 111, still not far off!

We're getting close! The funny part is the car is a total boat. To run these numbers at this weight is really impressive behind the wheel.

Not a 720S contender, but a 991.2 Turbo S is in trouble.

So 6 months after the official release (BMS 3.5 months) the F90 is running low tens. Out of curiosity, how many months did the F10 need to run low 10's ?

The AWD makes it too easy with the F90.

Do you have any stock vs various JB4 stages of boost 100 to 200 km/h that you can post ? Stock 991.2 turbo S was 6.8 seconds stock and 6.4 modified. Just how the F90!compares.

The testing we do is for internal R&D and durability testing. Sorry I don't save 100-200kmh in the app. Jason was doing the runs recently but his app didn't even have 60-130 enabled in it.

Any dyno runs with the same setup as the car was running with the 10.4@134?

How much faith do you have in that accuracy? 2.6s 0-60? Shouldn't that be a breaking headline news that is plastered all over the internet? lol

You did 2.6s just by brake boosting? How high can you rev it before launching?

He stated launch control was used, not brake boosting. Also it says 2.7 0-60, not 2.6.

Curious on a couple of things that I dont see have been addressed anywhere. My plans are to only run map3/custom map for racing only. I do not plan to run it daily. Race gas is not easily available in my area however 93 is. I have used octainium in the past but is methonal a alternative to the higher octane that would be needed and is there currently any support of that on this platform?

You can buy a 32oz container of Boostane on Amazon Prime and get it shipped to your door in two days. (You need a 5$ fuel funnel too)

The Boostane mixing chart says to turn 93 into 100 you need ~1oz/gallon of 93.

For racing you shouldn't want a full 20 gal tank anyway (weight) so lets say 1/2 tank or ~10 gallons...

Therefore a 32oz container of Boostane ($30) could last you three 10 gallon mixes....only 10$ per race night. Very cost effective way to get 100 octane equivalent fuel.

After race night is over you fill up with 93 on top and dilute it down to 94-95 octane for regular driving until your next race night

I read earlier in the thread that the JB4 should work fine for the Comp Pack F90 M5--has that been proven yet by any chance?

So far data has looked fine so you're clear for takeoff! Definitely post some logs here though or email them in so we can continue to monitor.

We've got some higher boost test maps for those running unleaded racing fuel like MS109, for those few of us interesting in pushing things further. Just email me for them for now.

Finally, we've gotten word from some customers that the latest BMW update breaks the code delete function. Similar to BMW's B58 update. We found a work around for the B58 and will adding the same patch to the F90 JB4 next update.
