I already brought the bm3 tune from their website this morning, and will try to flash it tonight or maybe this weekend. The current mileage of my car is about 22k miles. So I will change plugs at next oil change (30k miles). After some research, there do have some bad stories regarding to the injectors and coil failure, figure crossed. The extended warranty of my car gonna be ruined for sure, but I hope the tune will worth the risk. Btw, if I daily drive below 3k rpm, the flash tune won’t affect the lifespan of the engine plugs and other components right?? Cheers |

The bottom line is this: when driving around town in a normal fashion, you are utilizing very little boost and thus the engine is under very little strain. This is true with or without a tune. When having some fun, BM3 and other flash tunes are stressing the engine a bit more, but you are fairly safe with a Stage 1 tune. Change your plugs as per your tuners recommendation, perform normal maintenance as per BMW's recommendation (with the exception of oil changes which I would ALWAYS do at a more frequent interval), and be prepared for the random part failure, just like any other car. I would not go changing anything else preemptively with a Stage 1 tune. It's just a waste of money. Even if BMW flags your car for a tune, not all parts loose their warranty. For example: it could be easily argued that an ignition coil is under no additional strain due to a tune, and therefore a failed one should still be covered under warranty. This would apply to a myriad of parts. But, if you bend a connecting rod or crack a valve, your on your own.

I agree with what others said. When I was looking at X5M I stumbled upon a pdf that stated that engine lifespan only starts to shorten starting from 750whp for X5M with S63TU engine. Our N63TU is a bit weaker than S63TU, but on a level of Stage 1 that tops 530whp (max so far) - I think we are on a safer side.
BTW Bpc build a S63TU with only upgraded parts been sleeves, pistons and H-Beam rods that dyno 1500+whp - now that is something I want one day. This is their M5 with just 1026+rwhp https://www.bilibili.com/video/av18297161/ Last edited by DuSh; 06-28-2018 at 03:18 PM.. |

Hey guys,
I got last question, what’s the benefit of using plugs from X5M? Is it one step colder compare to the stock one? Also if I use a colder plug, during normal drive, will it be not hot enough to burn off combustion deposits? Any harm if I stick to the stock plugs? Thanks |

However, stay with stock X5 plugs for now, I'm still on stock plugs too. When/if you'll start seeing some misfire issues (chances are you'll be fine) then you can swap them for X5M plugs. You don't have to change them right now. Just wait for next maintenance - whenever that is. All we are doing is matching proper plug with proper output. Stock X5 plugs were not designed to be used constantly in 100whp increased engine. Temperatures will go up, plug tip will get hotter and eventually will start skipping spark causing misfire, it can also melt - but that's extreme we don't have to worry about. As for deposits - they'll burn just fine even on everyday driving. You are going to change plugs anyway every 30k miles or so if tuned. Also, I'm not an expert, so this is only my opinion man. Let's hear what other say. |

Ok, Please listen carefully. When you are ready to flash, make sure your laptop firewalls and security options are set to off. Put your battery on a charger as the flash can take 20 minutes. Turn off all non-essentials - lights, radio, etc. close the door, roll down the window so you can breath. Plug in your seat belt behind you. Once you are into flashing mode, make sure to select FLASH (SKIP CHECKS). For some reason, press here to flash now does not work correctly. Once it is finished, cycle down and wait 20 seconds before restarting. You should see a prompt that it was successful. After you start upon a successful flash, if you get error codes (which I did) like drive train, fuel something or another....then you will need to hit the ONLINE RECODE option. It will do a mini flash and cycle off. When you restart this time you should be solid. Good luck! |

Everyone talking about engine lifespan with an additional 100whp. That is nothing for these cars, if something were to break, it probably would have broken without the tune. Assuming you have a good tune, proper octane, and maintain your car, running an extra 100whp on the 50i won't effect anything. Only lifespan it will reduce is plugs.

No more misfire codes with BM3 stage 1 tune after swapping to X5M plugs and changing coils. Max boost of 20-21 psi with solid timing and fuel pressure according to the datalog.

There's a new version for the stage 1 tune from BM3. Not that it's 100% accurate but I noticed the sport display dial with the updated version now goes to 640 hp instead of 480. Looks like the line was just touching the 600 mark on my WOT runs (yes this was the hp dial not the torque dial). Stock tune would hit around 460. Again, I'm not saying this is accurate by any means but it's interesting nonetheless. |

If anyone is considering changing their coils... you can get the OEM Bosch coils on ebay for about $20 each. Ebay is also having a 15% off everything sale on all purchases over $25 today only.

Yeah, if you guys have true 20-21psi - then 530whp sounds about right and hence about 600hp at least (if not more) at the crank. Looks like you guys are highest so far.
P.S. Just wait me crank up my Bpc Stage 1.5 to 20-21psi - and then we'll see Maybe I'll be lucky to get to 550awhp P.P.S. Is there a tune for E40 at BM3, have anyone seen something like that? Just wondering |
