Your 60’ times should be lower if you could cut it down to 1.7-1.8 that would be worth quite a bit, they say for every .1 on your 60’ worth almost .2 on the back end.

There is definitely room for improvement there but that's gonna be tough with street tires! I have some other theories for my slow ET's as well:

1. Car is heat soaked off the line, hence slow 1/8 times. Once it gets moving IAT's decrease, ECU adjusts and car performs as it should.

2. Keeping DTC on (Sport+ mode). I will try DSC off and DTC off next time (comfort mode). I believe DTC is intervening and slowing the car. Tested this out on the street and the car pulls 1-2 so much harder with everything off. If I do this then I won't be able to use LC.

I have heard lots of people doing this with switching everything off as it helps , you should still be able to probably break boost to 2500-3000 and leave the line. Good luck!

Yeah... heat soaked doesn't help. However... I'm here in Tampa, FL and still able to get good 60ft, 0-60 and working on 10 sec 1/4 mile times. You definitely need to turn all of the nannies off to get the optimal launch. Hint... brake launching is much better than using launch control in these cars. If I can figure out how to attach my dragy slips here I'll post them up. Anyone?

Do we know anyone who installed the Active Autowerke catted downpipes for the N63TU? Would love some feedback!

Bootmod3 Stage 2 93oct
ARM Catless DP
Muffler Delete
Tried a ~20% E85 blend

Went to 1/4 track and best time was 12.822 @115MPH, very disappointed.
Somethings gotta be up right? Used launch control every run and I consistently ran 12.8/9. IAT's were constantly 40-50F above ambient (80F) and it was very humid outside. I dont have any proper logs but according to Bimmerlink I was hitting 19psi max during the run. I'm gonna build a custom intake and hope that helps for next time :\

Went back last night with the following changes:

Added some Boostane (98oct)
Custom front mount intake
DSC/DTC fully off

Best timeslip attached below.
Wow what a difference cool weather and launching without TC makes! Not sure if the intake made any difference though since my IAT's were still pretty high. Still need improvements with my 60' times, better tires next year will change that (I'm currently running all-season Continental ExtremeContact DWS) and help me break into the 11's.

Much better !! Your car should break into the 11’s no problem . Good luck.

Well...I hit 10.97 and 10.98 1/4 mile times. 2.99 and 3.00 0-60 (this is without 1ft rollout). 2.81 with rollout on both 0-60. Times were using dragy. Times should go down once I go to the track. I'm trying to figure out how to attach my Draggy slips here. Any help would be great...

Your car is a beast nice results!!

New guy here! I got my X5 50i a few weeks ago and took it to the track yesterday. 96k miles Completely stock
ran a 12.8 a few times, not sure of the mph and didnt get a slip. will be going back friday

Anywho, for those running BM3 would having catless Dp on a stage 1 tune have any benefits? or would i have to buy stage 1 and 2 and switch back and forth? Its my daily but dont want catless everyday just race days

You will knock off a sec in the 1/4 should be high 11’s , plenty of results if you search good luck

You still running bm3?

Actually no , I was contemplating but here good and negative reviews so was on the fence but I have seen a few guys on the board with bm3 or some sort of similar stage 1 tune running high 11’s . Did you give up on the bm3 ?

[txgrown]

Anyone running DME TUNING? Trying to look at all options before pulling the trigger this winter.

Is that with stage 1 and Dp? i seen the guys on here in high 11s with stage 1 and no dp. trying to see if its worth making the jump to stage 2 and getting more since they're the same price

I have heard they run that with nothing more then stage 1 and 93 octane no dp as you need stage 2 for that.

So I'm a glutton for punishment and wanted to see if the issue was this tune or because my prior engine had 97k miles on it.

For the past week the new engine has run amazing, completely new short engine, new coils and new plugs too. I flash to stage 1 93 tune and let the car get to operating temp. Literally the first log I get a knock event and the acceleration feels like im driving a trans am.

I took a 5 second log and I'm a moron for not doing this before, BM3 on their stage one tune is way too aggressive. I've included a log and this ots tune is an engine breaker. The amount of ignition they are running at such low rpms is a recipe for disaster. Unfortunately, I can't see what the IA targets are for the tune but they obviously want people to feel it in the butt dyno and the way you gain that is through torque. I can't see any reason for running this kind of advance on a stage 1 tune. If this was an E85 tune, I'd give them a pass but one a 93 tune with engines that don't typically love high advance, this is moronic, stupid, idiotic, etc......

I'm all of the names I listed above for not logging and checking this earlier.

Thanks for posting !!

As a reminder to people, IA is used can be beneficial at low rpms to help remove the appearance of boost lag while the turbos spool.

I've wondered if the RC XLR pedal tune can cause the same issue. Could it be that the motor needs that throttle delay to avoid opening the throttle before the turbo kicks in?
