After doing a couple data logs I went to use the share link button and instead of giving me a link it loads the graph with a download csv button but doesn’t provide a URL to share or ability to get out of that screen. I have to close the app and go back in. Running version 0.10.074

the issue with no license.. i get that too on android app. this started happening when they implemented auto-login. have you put in an issue ticket?

Ok so it’s an app issue not just for me. I have a case open currently and have put these details in. I’ll let them know it’s affecting android as well.

My data logs share link issue is being fixed in release 0.10.076 coming out soon

License missing from auto-login requiring a log out and back in to resolve may be fixed in this same release as they can’t reproduce it on this version. Hopefully it’s fixed.

*** UPDATE:

B48 Engine Vehicle support now available through bootmod3:

So to confirm, if I want to add mild burbles I need to put ASD on now? I thought previously ASD had to be off.

Why did you removed blue LOG button form dashboard... It's very difficult to start logging now with double click anywhere, and you don't have any feedback if it's even logging... I missed at least 7-8 logs because of this... very user UN-friendly approach! Please bring the button back!

Hi, i'm driving a 320i N20 engine. What gains am i looking at for a stage 1 tune? I understand that my piston compression ratio is different to that of a 328i and i will not be able to make as much power as 328i for sure, but would like to find out more and see if it is worth doing up the car. Thanks!

[floridaorange]

You'll 100% be happy with BM3 stage 1. Im running BM3 stage 2 AGG 93 octane, in my 320i, and the difference is huge from stock. I was told stage 1 is a nice step up though. Besides the tune, there really aren't many other options for you to greatly increase the power. But I recommend catless downpipe if possible.

Thanks for sharing. Had planned to go stage 2 but a little tight on budget for now. Still short of a catless DP and FMIC. Thought of getting VRSF for both since their price is really good. Is it a good choice?

[floridaorange]

It's a fantastic choice - can't go wrong with vrsf.

I think I spent around $450 for both my fmic and dp.

I had Stage 2 AGG, Octane 91, on my N20 F30. Had all the recommended hardware, including decat exhaust, wagner tuning front mount intercooler, FTP charge pipe, FTP boost pipe, GFB DV+, injen evolution cold air intake.

Last night, when in sport+ and driving around 160km/h on 3,5k rpm, my engine suddenly knocking, and drive train error shows up on the i drive. Scanned the error and got the following error code:



Bring the car to local BMW dealer, and after they tested and inspect it, my piston on cylinder 3 was cracked.

They said, because of too much power and torque, the engine's internal can't handle it.
They previously encountered more than 10-N20 engine that has the some problem because of the aggressive power and torque from remap.

The quoted me around USD 2,500 (excluding VAT) for the repair, which is huge blow to the pocket.

I will post my engine's internal once they open it up.

I just want to remind all the N20 user, not to remap with too much power and torque on engine, or they will blown, like mine.

Sorry to hear you blew up your piston! This is first time I read about broken engine with BM3 tune. I know some other off-the-shelf tunes that adds so much boost that engine can't handle it in the long run.

Did you log your engine after flashing Stage 2 tune into it? I had some knocks with Stage 1 93 (98RON) tune even though I used 93 octane fuel. PTF said that I should try different brand fuel next time. I switched to Teboil 99RON (94AKI) fuel and it helped with the knocks. However, since this 99 octane fuel is not widely available, I flashed it back to stock. I had planned to step down to 91 tune but continue using 93 fuel to get some headroom. It's now winter in Finland so I can't use even all of the stock power so I have time till next spring before trying Stage 1 91 tune.

Looking forward for your updates about this!

Edit. Oh forgot to add that car felt so much quicker after tune. I guess you feel added power more in 320i than in 328i because it gets higher bump up in power in percentage.

Maybe i'm just out of luck, to get my piston blown.

I use the same method as you, stage 2, octane 91, and using RON 98 fuel to have some spare.

I already log when i flashed to stage 2, and it has no issue, 0 knocking. I'll try to find the datalog when i have time.

After they checked, my cyl 3 has no compression at all. Thats why they said that my piston was cracked.

I'll update again once they finished open my engine to replace the piston.

I said it once, i'll say it again.

N20/N26 motors are the most fragile engines in the world, I've always recommended people to upgrade to the N55 or B58 unless you have super deep pockets to rebuild the N20/N26 after the engine implodes. It's not a question of if it will blow up, but a question of when.

I guess N20 is made with cheaper internals compared to N55 but I don't know if I would go that far to say it's the most fragile engine ever. Problem is that six cylinders are crazy expensive in Finland (and I'm sure that's the case also elsewhere, just maybe not in US) so you can't afford one even if it's pre-owned. 320i costs ~40k€ and 340i ~80k€ without any options. Add some 20k€ for all bells and whistles and you understand why it's tempting to tune N20 instead of "just upgrade" to six cylinder. If it would be only ~10k difference in price I guess almost no-one would choose four pot instead of smoother and more powerful straight six

[floridaorange]

How aggressive would you say you push your f30? And how many miles does it have on it? And have you had any other issues of any kind? Sorry that happened mate.

[MilanF30]

Is this 320i or 328i? Just asking because they have different pistons for compression ratio

Buy it used, or get the new B47/B48 4 cyls. They're made better.

[Cpatel]

Can you remove the N20 engine and swap it with the B58?

You can do anything as long as you have the $$ to pay for it.

I'd just buy another car instead.

I have the B46 now in my 430, I'm going to give it to my daughter and buy a car with a B58 or better.

Noted with thanks.
Local BMW dealer also said the same, after my piston blown. The had encountered around 10 N20-engine that blown because the engine can't handle all the power and torque from remap.

I guest i'll switch to N55 6 cyl engine after i sold this car

same here
N20 BMW cost around USD 24.000, while N55 BMW cost around USD 49.000
the best choice maybe the new B48 BMW, which cost around USD 34.000

i had no other issues, no malfunction, and always has its periodic service done by BMW

i would say, sometimes i push to 6.5k rpm, but mostly around 3-4k rpm in sport
when my piston cracked, it has around 36k miles, which quite low in my opinion for 2014' make

320i
but local dealer also had experience with 328i engine destroyed

[floridaorange]

36k miles
