I'm at a work event. I was happy to share logs, but this is not the reaction I was expecting out of enthusiast. I'll follow up. Not trying the be tricky here. I have nothing to gain other than $10 in YouTube revenue. No biggie to me what you guys think. I provided more results than most take the time to do.
This isn't about respect given or owed, people just want information. That is expected considering your title says it is 'insane' which can be viewed as unbelievable.
We would appreciate any information you're able to provide. Thank you for sharing.
Understood. It took me over 35 hours to produce that video. People can be patient for me to release more info without talking crap IMO, but I get it... results surprised me as well
There will always be those with opinions. Remember this is BMW land, our opinions matter MOAR.
If we can get some more supporting details I'll promote this to the front page.
The more data the better. You can't expect people not to be critical. That is not a bad thing per se. The more vetting the better for everyone.
If these are real gains any n55 owner can see with a tune and 1 junk yard cam this is great news.

I'm just going to highlight this again.
Duration of stock exhaust cams is as follows- at 0.020, 0.050 and 0.200
N52 used- 221.2*, 190.3*, 74.1*
N54 used- 216.5*, 192.9*, 75.8*
N55 used- 216.4*, 192.9*, 76.9*
Standard measurement for comparing cams is at 0.05". So the N52 exhaust cam actually has less duration than both N54 and N55. It has 5* more duration at 0.5mm of lift. I bet if your tuner actually adjusted the stock cam you would be making more power.
If you have logs from these pulls to share that would be great. As of right now it just looks like you went from a bad tune to a better one.

Do I need permissions upgraded to attach files or is my phone just acting up? Pixel 2 XL. Can an admin upgrade my privs if I am limited? I have my logs all sorted to share.
Ok I got them uploaded. How do I share the datazap here? I started with just the N52 vs N55 cam, same tune. Next I'll upload the N52 after fine tuning

You have to save the datalog with the csv files. Once it is saved you'll see it below the graph. Choose public or unlisted privacy.
