Still want to know what the best rpm to shift at in each gear etc...

i dont use manual, ever, always auto shift. I use manual to set up my 60-130 run but then double tap shifter to go back to autoshift.

Finally stage 2 flashed.

Attempted to turn off cold start though like others its a little rough running when cold so I switched it back.

Good news, I can turn off burbles, thank you bm3

Did a log, attached log https://www.bootmod3.net/log?id=6147...90c67cf11488ca

Comparing stage 1 e30 and stage 2 looks like the timing is increased some but boost is still the same. Also wondering if its normal to see so much difference in timing between cylinders.

Update: ran a few attempts with the dragy today but weather was not on my side 2200 da 82 degrees and 95% humidity, still pulled better time than stage 1 93 but nothing to ride home about. Looking at BM3 % power increases between stage 1 93 and stage 2 93 its only 5% increase. Seems only way to get more performance is better weather or better fuel w/ E30 OTS file.

cool datalog info, never seen that one before thx. Your tune looks healthy bro

Crappy weather conditions, I so miss the fall/winter temps and humidity, feels like a wet sponge ever day with 85-95% humidity

Anyway wanted to run stage 2 93 file with the CTS catted dp's, drop in filter and light weight wheels. Happy with the performance being on 93 file as well as the weather condition. Seems the stage 2 93 file doesn't add any more boost/timing, its basically just better flow increasing power I believe (someone correct me if i'm wrong) Eventually will run the E30 stage 2 since it shows it pushes a good bit more power, but more wanting to wait for better weather since that alone makes a difference.

Also wanted to share how enjoyable the BM3 is to use, flash and log.

0-60 stock = 3.04 / BM3 Stage 1 OTS = 2.87 / BM3 OTS/TCU rear seats out = 2.93/ Stage 2 93 = 2.81
1/8 stock = 7.07@100.27 / BM3 = 6.88@103.08 / BM3 OTS/TCU rear seats out = 6.80@104.47/ Stage 2 = 6.79 @105.08
1/4 stock = 10.98@126.62 / BM3 = 10.68@129.72 / BM3 OTS/TCU rear seats out = 10.55@131.17 / Stage 2 = 10.52 @132.46
60-130 stock = 8.43 / BM3 = 7.87 / BM3 OTS/TCU rear seats out = 7.53 / Stage 2 =7.24
0-130 stock = 11.65 / BM3 = 10.74 / BM3 OTS/TCU rear seats out = 10.46 / Stage 2 = 10.17

Nice runs man, we are very very close!

Looks like taking the seats out helped quite a bit??

Agree she's moving on 93 with shit weather, i'm pretty happy thus far.
Only did that when I was on stage 1. Crazy what weight does.

You're def making some good TQ. That's where our power curves differ. Downpipes are def making good TQ down low paired with the TCU. You have the Titan wheels also right? Great numbers man!

tcu ? meaning you also have xhp transmission stage 3 tune as well or no?

[brad65ford]

Yes I have the titans on. Agree I can tell she’s more torquey and so snappy right now. Can kick the back end out in 2nd with ease lol.

Correct

lets get to 60 degress sea level with e30 stage 2 seats out and tcu this is a 6.00 60-130 cae i guarantee it ima do the same thing here in cali and do draggy as well !

[brad65ford]

no doubt, I'd be happy with 60% humidity right now lol. Seriously when you see 85-95% humidity with 80+ degrees just say no to doing dragy runs, totally not worth it. I've done so many dragy runs with multiple performance cars over the last few years. Its crazy how much a 50 degree day with -500 da w/ low humidity makes a difference. To run 6's for 60-130 with 93 octane with 4k lb sedan I'm happy, couldn't do that in a lot of other cars i've owned, needed E85 to do that.

Hey, nice numbers!!! Can you please post a log of your 0-60mph? If you remember, i had a 2019 Comp that no matter what doesn't want to get under 3s for 0 to 60. I want to compare my logs with yours for the Launch Control with shift points, boost and etc..
thanks in advance!
Heres my 0-130mph, as you can tell barely broke 3s 0-60 and im going faster past 100. Your car seems to launch insane. (This is HCP Stage 2, xHp Stage 3, 93 octane)

Thank you but its not me its the car post #112 above has a 1/4 mile log I believe which should show the 0-60 in there.

I edited my post take a look

What rims and tires do you have? Also try a different location/ surface. Sounds silly but you’d be surprised I was. I ran on new asphalt thinking it would be an awesome time but it was the opposite

Michelin Pilot Sport 4s, and Stock rims. I went to the track yesterday, 0 wheelspin best i could pull was 10.46 1/4 and 2.92s 0-60.

[brad65ford]

I have ps4s’s too. They aren’t the greatest for hooking up, mine are new so might be helping. The Titans I purchased is helping with the 0-60 , 60’ times for sure. Your not that fair off from me .10 isnt much. Check out the weight difference of stock wheels compared to titans. It makes a difference

good stuff why are you mad those are amazing numbers what mods do you have?

Totally agree

Oh i am not mad at all, im just playing a detective here 😂.
You probably didnt see my other post but here is the story. I have a 2019 Comp and a friend has a 2020 M5 Base. Both cars have same rims and tires. Only difference is my car is running stage 2 93 Octane, xhp stage 3, DP. while buddies 2020 is running stage 1 tune with DP. When i launch his car and time it, it just feels like it shifts quicker and every time i launch it i easily achieves 2.8s 0-60 consistently!
Now with my car i launch it and its always 3.06-3.1 area. So ive been trying to track down the difference, unfortunately i cant log my friends car because he doesn't have BootMod3.

This is where this thread comes in, when i get home tonight i will play some detective work comparing the logs and shift points and etc 🤣.
