I need make some corrections. I figured out the big gain of rear wheel "spin" from stage 1 to stage 2 was mainly due to my rear tire change, which happened with stage 2 upgrade. So now I have to say the excitement gain between stage1 and 2 is not as much as stock and stage 1, even though I certainly felt the power/torque gain. To numerically verify the performance gain(i.e. 0-60), first I need to burn off these poor traction tires i got.

Update: I figured out why my FlexFuel install wasn't working at first, seems as though you need to make sure you fully twist and cap the spliced wires from the JB4/Stg2 wiring loom.
I'm running Map 2 with my mods (Magnaflow catback, AFE intake) and a 40/60 mix of E85 and 93 octane fuel. The N20 engine is a monster now; completely different beast than it was running the same mods with Stage 1 and 93 octane. I'm going to move up to a 50/50 mix of E85 and see what Map 7 brings. My hat goes off to Terry and the rest at BMS, I'm more than impressed with Stage2. |

Also, I just found out that there is an updated interface download from BMS as well. Haven't installed it yet but just FYI you can get the updated interface from this thread: http://www.n54tech.com/forums/showthread.php?t=17441 . |

One thing that I worked through in moving up to 50/50 E85 and Map7 is that right after I made the switch, I encountered a fairly consistent 'misfire' issue on 3/4-WOT in which the engine would completely bog down, almost as if I hit a rev limiter. No CEL or codes would result and as soon as I let off and eased back into the throttle, the engine would return to operating without issue. I am running the FlexFuel wires and had set the openloopfuel setting to 60 in the JB4 interface. However, after doing a bit of forum research I believe I discovered that we should also be setting the futureuseB setting to 2. After doing that and bumping the openloopfuel setting to 75 (remember to let the car adapt too), the misfire issue is completely resolved and the engine pulls and pulls and pulls. |

Secondly is it normal for the car to be very rough on cold starts? I have found a couple of times it will start and then struggle and then turn off. When warm I don't have such a problem |

Guys I just Installed S2 on 528i F10 incase you were wondering if it's compatible because I contact John@bms but he said he didn't have any customer yet (guess I'm the first ) so I had to take the risk but you have to know you'll need longer wires for green and brown wires so you can tuck the module beside the brake booster.

All this talk about running E85 mixtures...why doesn't anyone run 100% E85? Can anyone speak to the downsides (re: issues with the fuel system, codes) of running straight E85 with a JB4 Stage 2? It would be more convenient that to worry about mixing every time.
If this has been discussed, spare me...I'm not going to comb through every single post in the thread. |

After a lot of reading it seems like when the initial enthusiasm fades away, the gains are not really anything to boast about. I've never seen a before and after Dyno from your average owner (not a brand enthusiast), on average octane (91).

Hold Volume (-) for 5 seconds, then press either (+) for map 1 or (-) for map 0. The full control from the steering wheel should be added soon. DL the JB4 comp interface from here http://www.n54tech.com/forums/showthread.php?t=15536 |

No, I don't know about the navigation CD although I did coding for my car and my dad's F10 and I contact someone who's responsible for maps and he said there are no maps for Egypt but that was 3 months ago, I'm waiting for the LCI to make any changes. http://www.f30post.com/forums/showthread.php?t=853049 Last edited by rustyminded; 09-13-2013 at 02:59 AM.. |
