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 🤣.

i recommend you try e30 stage 2 to see difference and maybe get better air filters or even the dinan turbo inlets or even change new plugs you never know what you can do to tweak and find even better r0-60 times

for the bm3 off the shelf map can you use e30 stage 1 without replacing the stock downpipes no primary or secondary just the stock ones or even on stage 1 you have to ?

Correct

Stage 1 91 octane: up to 11%HP / 18%TQ
Stage 1 93 octane: up to 13%HP / 19%TQ
Stage 1 E30 octane: up to 19%HP / 26%TQ
Stage 2 91 octane: up to 15%HP / 22%TQ
Stage 2 93 octane: up to 18%HP / 24%TQ
Stage 2 E30 octane: up to 24%HP / 34%TQ

i was talking to a custom tuner he was saying don't get e30 stage 1 and advised me to replace all 4 downpipes and e30 pushes a lot of boost so I don't know

Not sure honestly, though its been done many times over before. Its said the stock DP's quality of cores are strong and can take a lot of abuse. But most likely better for the engine to breathe especially on more timing/boost/ethanol etc.. For what its worth I'm a little nervous to run the E30 stage 2 lol

e30 stage 2 seems fun and very powerful I wonder how e30 stage 1 does on the stock downpipes

[brad65ford]

I ran it for a fuel tank and did a dragy I believe. It wasn’t majorly quicker. Figured very similar to stage 2 93

e30 stage 1 without downpipes?

[brad65ford]

Believe that is what stage 1 refers to.

if its similar to stage 2 93 that is pretty impressive

Sooo, did some detective work, comparing logs, here is my pull on Stage 2 93 Octane of OTS.
Looks like your car is shifting a little sooner than mine, also for ignition timing mines goes into negative value, im not sure if thats bad... any Log experts?

[brad65ford]

Thank you for sharing, starting to look at it now. Its nice to see that mine isn't the only one that has different ignition timing 1-4 values which seemed odd to me.

Looking at them between one another you are correct mine is shifting earlier, when in auto its like 7200 which I hate.

I'd write xHP on this, also drop this info in the xHP thread. I'm all for keeping information in the correct thread even though this is the some tuning thread, it may be xHP tune related?

Also mine goes negative to when shifting.

I laid out the difference between them, seems mine is smoother. How many miles on your car? If anything I'm wondering why my actual boost in the upper gears are lower then higher, might be the norm not sure.

Only one cylinder does, which is weird. Im not sure it could tell knock on individual cylinders, but I am not sure. You might want to change spark plugs if they haven't been done for a while.

Your timing is decent around 13-15 degrees, boost 21-22, seems like a conservative tune for 93 octane.

Just hit 18k miles. I will try replacing the spark plugs. Thats going to be a job. I did have a knock detected when i did a e30 map, so i figured maybe my Ethanol wasnt mixed correctly and went back to 93 ots. i always do a log before going on certain map full time to make sure i dont have knocks.

Plug change for sure, the car will run way better.

[brad65ford]

Hence the reason I posted that plug thread and the plug condition at 18k . Nuts how bad mine were. I’d do them soon before doing any more dragy runs. Crazy if it smooths all those peaks out. If and when you do plugs, please post pictures of them on that page, would like to see others change there too especially at that mileage or sooner.

[pbonsalb]

When I changed plugs on my 18 with 30k miles a couple of weeks ago, I noticed that several plugs were loose - barely hand tight. I think I read of one other person finding a loose plug. Not sure how loose they have to be before the cylinder loses pressure.

[brad65ford]

You have pictures of your stock plug you can share?

[pbonsalb]

I tossed them already. But they looked like yours. I did check gap on a few and they had opened up from 0.026 to 0.027-0.028. Yours looked OK to me — color was good, a little crusty but that sound clean up with a wire brush, they were firing fine since the car was performing well, and the gap had not opened up. I doubt they were causing any trouble but I do agree with closing the gap a bit on the new plugs and using a colder plug if adding boost. I went to 0.022 and 2 step colder with no noticeable side effects such as poor idle. My car has only JB4, carbon filter delete and 70/30 meth/water controlled by the JB4 with 93 pump. Need to take the time to log and dragy but have not yet.

Would love to see your logs, either PM or post in my thread for comparison!

Anyone attempt to alter there burbles with the BM3 software? Recently removed all burbles after doing DP's since it was just to nasty imho. Anyway going to attempt to add some subtle ones in. Not sure if there is a happy in-between.

So much for having that functionality on the BM3 with the F90 platform. Just will not allow fine tuning, even at lowest settings its either snap crackle and snap/bang or off unfortunately. Attempted many different settings but can't get it to just do a rumble for a short period of time. Shame since I was able to tweak the F80's like butter to what I wanted. Off it is.
