yes I am....The car is amazingly faster. Going to take off the BMS, install the P3 boost gauge, take it to the dealer for correct Dinan tune install.
Car will hopefully be even faster but I have no faith in Dinan as I think the tune is already installed and it just isnt such a great tune. I donno though, we will see. Furthermore, if Dinan tune was installed and I stacked the BMS, wouldnt the engine be blown already????? This proves that I was only boosting at stock levels because let me tell you that the car is moving ass with the BMS tune. Last edited by dmetuning; 10-17-2013 at 02:09 PM.. |

I believe the tech gets an acknowledgement that the software is installed, but once installed it doesn't seem to be hitting the boost target for some reason. I would think that this situation is still different than running the stock maps, as they are changing more than the boost tables. I don't think anyone has blown an N63 from tuning so there's no way to know if stacking would blow the engine, or how much boost is too much. Damage to the engine can happen over time, it doesn't have to be all at once. You should really be logging things like boost (with a mechanical gauge now that you have a piggyback), timing, afr, etc. to know if your engine is ok with the setup. The thing that would worry me is that BMS are requiring 100oct to run their aggressive tune, which I believe is only ~2psi higher than their base tune. This makes you wonder how much room there is to add boost without changing other parameters in turn (which I don't think BMS does) before you risk damage. If stacking does work for you, and there is data logging to support that it's not causing damage, I bet this would become a very popular option. |

The aggressive map is more than +2 psi, I believe it is more like +4 or +5 |

Your car is probably pulling timing due to knock at that boost level - looks like you found the sweet spot for this tune on your car...

I ordered the BMS logging cable and a p3 boost/temp/etc gauge and I can report back my findings in the next few weeks once I have installed it all and have some credible results. I asked BMS if I needed to make any adjustments to their tune through the logging/programming cable that I ordered based on having an exhaust and air intake and they told me that their tune is adaptive as is the stock mapping in the car so both make adjustments based on the exhaust/fuel/air/etc and conditions that apply in my vehicle. Meanwhile, the car is flying: Furthermore, the reason why i am so brave is because the lease it up in 7months....lol Last edited by dmetuning; 09-19-2013 at 05:03 PM.. |

Misunderstandings usually have two very different perspectives. From my perspective, I thought you were being confrontational with an outrageous performance claim and I called you on it - no insult intended, no sarcasm. If your (misperceived) claim was true, it truly would have put BB's results in a new perspective for me. Same for the 100 Cetane requirement; a tune that only needs 93 Cetane can't compete with a tune that requires 100 Cetane. Likewise, after rereading your post, it still looks like you called me a troll whether or not you qualified it as being childish. I read it as you launched a personal attack against me and then tried to take the high road, so as not to look bad. As I said, two very different perspectives. It's all cleared up now, so no hard feelings. BTW, if you had produced a stock 12.4 timeslip, you would have had me bowing in respect. Quote:
Anyway, it all was a misunderstanding. Maybe you can understand how someone could misunderstand someone posting "A lot of us result in the same range as he does with stock possibly best at 12.4-12.7 contingent on weather and reflex" and thought he was talking about a stock 550xi and not 550xi that is stock except for BMS. I didn't perceive "same range as he does" meant "the same range of BMS psi as he does" rather than "the same range of skill and/or performance as he does." Again, it was my misunderstanding. Nothing to do with Dinan or BMS. Finally, I think there is one more little misunderstanding between all of us, (other than BB and Alextremo, since they actually know) neither of my Bimmers have Dinan installed. True, I have owned a Dinan car in the past, but I have also owned other tunes too.

Luckily, the car got fixed and you don't just feel an increase, you see the speedometer moving a lot quicker than before . DINAN is definitely not giving the full 520+hp they claim, but it is definitely a significant improvement over stock, however I agree with @middly that BMS is the better tune overall (price, performance, etc.). Guys, we are all mature BMW owners here, not 1st graders. Please, no arguing over what tune is better. People have opinions, let them be. @dunderhi is not a bad guy, he just has a soft spot for DINAN, I believe he was one of the first to get the tune. I personally know @badblack550xi in person, and he is not as bad as he is on the forums LOL (just kidding). Seriously though, he will not however back down on a 1/4 mile challenge, and will always believe BMS is superior, however I want to see what his car runs on just stock BMS tune, not juiced up for 4+ psi. Btw, does anyone know if you can stack the BMS tune on top of the DINAN. IF so, @badblack550xi if you don't mind, I want to try the BMS on my car (if we have the same harness).

Sure looks like sarcasm and childish to me. If you were polite you wouldve asked "do you mean stock car like completely stock without tunes?" instead of being an ass and you know this. It seems more like YOU were trying to take the highroad after realizing highconcept brushed you off and wasnt having it. He has every right to feel you were rude, most people here think you ARE lol. That's why he simulate the way you talk to others, because it feels as though you are calling US trolls lol. And he's right, you do always try to get in the last word even after he made peace with you. You know its bad when Badblackxi had to explain it himself to clear up for you lol. I think you were already frustrated with the OP and BB then HC came along wrong time for him. Bro, you just gotta relax man. You are too on defense with things. Alright lets end this BS then and get along dude. Last edited by ClassM; 09-19-2013 at 05:49 PM.. |

I believe Middly's tune is not currently working, allowing him to use BMS. However, I haven't seen a DINAN w/ BMS.

All you do is type "@" and "username" together, and it should work. For example (not a real name), @ ClassM (no space between @ and the name) would be in a blue box. @ClassM
