Friend got a new measurement today with bootmod3 stage 2 and xhp stage3. Car flashed to 330 before, so if your car is a stock 320xi then you will not get this numbers:

What do you mean by "330"? Flashed to stock 330i map before bm3 or 330 bhp is the estimated crank power?

Flashed to stock 330 before bm3. As result bm3 detect car as 330 and there is more powerful maps available than for 320.

Thanks for the reply.

Well, since I have a custom tune with the highest torque for this engine and AT I would want (450 nm crank) I guess what I am missing to go below 5 sec 0-100 is the xHP tune.

It is a next thing on my radar. Btw. what are your tires? Have you measured also 100-200 km/h time?

Best regards

I have an F30/N20 320i with STG 2 BootMod3 / CSF FMIC / ER Charge-Pipe / Inejn Short-Ram / Wagner Catless DP

I'm actually going to dyno pull my 2016 320i tomorrow!
I'll post-up some slips/pics after complete!

I'm a little concerned with the # of people on this forum with blown engines on Stage II...

If my friend can blow his 1999 m3 with Dinan tune after only 10,000 miles - your N20 is gonna go too, it's only a matter of time with tunes. They speed up the aging process and put pressure on internals that are not designed for it. Good luck

True to a degree. Depending on the tune your stressing different parts, but what I was trying to figure out (from others experiences) is what's the "safest" tune to liven up the de tuned 320 with stuck internals.

Thanks to all the feedback, where I'm at currently is BM3 stage 1(poll numbers aside), is the way to go, haven't heard anything negative really as long as you take care of your car and don't mess with settings your don't understand, but I'll probably wait till warranty is over. Stock power for now 😂

With BMW nowadays you are not speeding anything imo. Time intervals for something to fail are random but it's mass is located very early in the car's lifetime.

My friend's N57 diesel for example had a timing chain replaced at around 15k miles. Another one's M4 F82 had the whole transmission replaced at 30k miles. Can you speed that up lol? Super OEM quality?

Please stop telling people this bullshit about "stressed intervals" "not capable to maintain" because of your blown engine. I get it but until you show me a research that compares reliability of tuned vs stock n20s we are just reading tea leaves.

I think @mike@x-ph.com wrote somewhere that from his experience there is no significant deviation between tuned and stock f30 reliability.

Quite right! I don't have empirical data to give you as to why my imperial blue 320i didn't last past 48k. And I did have the $3,600 option of replacing my engine (excluding liquids and gaskets). But my German Auto mechanic told me how common a blown N20 was. I didn't make that up, as you've eluded to.

Anyway, seems stage 1 may be the safe spot. I only ran stage 2 - as the gains were very addictive.

Seems that n54 blows too!

https://bmw.***********.com/threads/...p-an-n54.2157/

Subartu STI blows too!

https://forums.nasioc.com/forums/sho....php?t=2872741

Hondas Type-R blows too!

https://www.civicx.com/threads/so-my...p.34226/page-4

Jokes aside, please consider that the number of n20 on the street (similar with n47 diesels) >>>> number of n55/s55 therefore the number of blown engines on the forum is nominally greater.

However, we don't know much about even approximate distribution.
Unless pushed past stage 2 what failes would have probably failed under stock conditions anyway.

My timing chain and oil pump for example on 320i failed at 50k km, when I was still stock. Head gasket blown at 55k km, still stock.

I am tuned stage 2 since last 40k km, 0 issues.

maybe different maintenance and fuel quality also play significant part on the engine longevity

i previously had 2014 N20 320i and the engine was blown at 55k km

running stage 2 AGG BM3 for only under 1k km before the engine blown
had all the recommended hardware for stage 2, including wagner FMIC, armytrix catless downpipe, straight-pipe exhaust, FTP charge pipe, FTP TIC, GFB DV+, injen evolution CAI, and 2 step colder NGK spark plugs. Also change oil every 5000km

i had the same symptoms with floridaorange, rough idle, then drivetrain malfunction shows up, and after checked by BMW authorized dealer, cyl 3 has no compression thus the piston was cracked. Cyl 4 also shown a trace of unusual heavy wear, but still acceptable for the moment.

The said, it's due to the engine can't handle the power from remap resulting in internal damage
had to repair for US$ 3000, and sold the car for good.

now driving B48, and using stage 1 BM3, for safer and longevity of the engine

this is the picture of my N20 internal when the engine blown

i'm not saying that engine tuning with stock internal will definitely blown your engine, but i think the more aggressive the tuning the more it will increase the risk to your engine
Although i'm not to judge, because it's your car anyways

How much did you sell yours for with the replacement engine? What year and how many miles on the replacement? $3k is a great deal on that.

Hi, nice that you are sharing your story. Did you try to contact PTF about their stage 2 and impact on the engine? Seems to be something wrong with the tune, which is weird considering their expertise.

Also did you logged the car before and after tuning?
It is also nice to see those pistons on the real life photos.

Comparing them with the TSI 2.0 300PS for example these look much more solid - both the rods and rings.

Yes i contacted PTF and send the log with stock and tune
at first i'm using Stage 2 AGG 93 oct,
PTF said that my fuel quality is not good, and advise to use Stage 2 AGG 91 oct, but keep using the 93 oct fuel
i flashed to Stage 2 AGG 91 oct, and everything seems better, my car response better and the power feels more solid, send PTF the log again

but after i drove around 200km..boom.. rough idle, drivetrain error

in my country, the number of blown N20 engine due to remap (any remap, not just BM3), is quite large. My BMW authorized service center has encountered more than 20 blown N20 engine (both 320 and 328), with various damage from light to beyond repair. But for B48 engine, they never seen the engine blown, even after remap and pushing pas 300 hp, at least up until now.
