Misfire codes on the other hand are common around the 650whp power level especially with methanol injection. A misfire code just means the spark blew out before it was able to ignite the mix. There is no proven fix currently but most tuners think the solution will be as simple as closing the gap in the plugs a touch, or perhaps aftermarket plugs that are slightly more recessed. Mike |

I wish BMS would post up something regarding what boost setting they recommend for which octane.
There are for sure mixed reviews on what to set what at. I've contacted BMS numerous times and never get a straight answer. Where is everyone getting their info at or is everyone using their own judgment ? |

Always best to let it adapt for a little while.

It's probably best to look early on in the m5 part of his forum... Because once he got the car we were all curious.
I've run 2.2lbs no problem for almost 20k so now that 3 seems to be standard I'm sure I'd just run that. |

On my M6 I've been running BMS stage 1 new firmware 100 octane 5lb boost increase with no issues and airfuels low 12's for quite some time. been running 93 pump 50/50 meth mix 5lb boost increase no issues what's so ever with plenty of miles. Went to 93 pump 100% meth mix 6lb boost increase with air fuels low 12's high 11's as the gears increase up top RPM, also no issues. Now have been running 100 octane 100% meth mix 6lb boost increase with no issues and airfuels still low 12's high 11's as gears increase. Also have 2014 M5 with stage 1 BMS stock everything except K&N filters carbon filter delete running 93 pump 4 lb boost increase no issues The only thing I can think oF FoR someone to be having misfire codes is because they're not letting the car adapt to the new boost increase. Every time I raised boost I would do a third gear pull as I would slowly get into the throttle so the MAFs get a good reading. After a couple third gear pulls I would do a fourth gear pull ect. As I watched my airfuels they would get richer by every individual pull. Since this day I havent had any misfire codes and if I did believe me Terry would have been the first to know as well as posted on n54tech forum. Good luck guys!

As for my M5 I'm running BMS stage 1 with 93 octane and 4lb boost increase with no issues. Anytime I've raised the boost I would let the car adapt to the boost. Not killinging it or downshifting at first. I would do a third gear pull starting off by getting into full throttle easy and let off at the end of the gear. I would do this a couple of times on the highway and then do the same in fourth gear. The way I noticed this was from watching my air fuels as the first run would be pretty lean to the next would start to richen up. Also remember as the car would sit it would recalculate and as the days past the richer it got. I feel people are just jumping in there cars and thinking the car will adapt with a turn of the ignition. They have to be as smart as their car and let it adapt with time and patience. Hope this helps and good luck. Love my BMS can't wait for terry to push this thing into a JB4 Here's a new link I posted http://www.n54tech.com/forums/showth...d=1#post315088 Last edited by m6beast; 06-17-2014 at 12:49 PM.. |

Don't you need to kinda get on it though to trigger the underboosting? I mean its not like a flash tune you can gradually work in... If you're not triggering the boost its not going to adapt right? Quote:
Wouldn't be good for business if he hopped on the air and said we're offering a package for 650crank, but the internals of the DCT and Engine can take 850hp lol Last edited by M5Rlz; 06-18-2014 at 05:48 AM.. |

When I was talking about 1 gear pulls I meant full open throttle. What I meant by easing into it was so the MAFs get a better reading then just slamming the gas.
You're still flooring it just not in the begining for like a sec so the MAFs are getting a good smooth reading. after adaptation you can stomp on the gas how ever you want and when you want through any gear. As for my M5 is a DD with stock everything running 4lb boost and 93 octane with no issues. Running it hard but most of the time been cruising. Still catted so will heat soak faster. Will do DPs very soon. th Quote:

Also is the firmware version that of the car found in the idrive somewhere or the firmware of terry's software? Last edited by M5Rlz; 06-18-2014 at 07:55 AM.. |

When you open the jb3 on your laptop you change the boost settings and save them. After that run the car the way I said in previous post to adapt. Do some datalogs so you can see the difference of the boost maybe even datalog before and after. Let me know if I answered your questions |
