Can SOMEONE with access to a dyno do pre and post flash dyno runs? I believe it would very interesting to see what the new flash does to the power curve. Initial report of the new flash is very positive! |

I can see what we can do here. The updated map is only to help with low end driveability only. Top end power was not touched. We may be able to find a donor from our open house, and will keep you posted. Chris |

That would be great Chris. As one of those lucky enough to have a bike that doesn't have the driveability issues, I am trying to be diligent before taking the plunge--esp. after the mixed success of the first flash. |

Feelers are out for a donor, Fresno, I'll be in touch soon... Chris |

i'm down to give this a run....but i'm down in San Diego. but i fully intend on doing pre-post dyno runs somehow. |

For this "back to back" test to be credible IMO; Pre test on a well "adapted" example...ON a day that is most similar in conditions to that future day planned...or better yet, a controlled environment and by the same operator with plenty of notes. "Corrections" should be thrown out the window. Post test after allowing at least 200 miles, for the example to again, "adapt" to it's new parameters. HIGHLY important! Rear tire should be measured in diameter and pressure duplicated. In theory, the new injector "target" timing should have no affect on higher rpm regions...but the lower time/efficiency should only help. The same applies to the new load point ignition timing and/or parameters. Based upon what little information that we either know of as fact or have proven, a minor improvement should be measured but not due to the above. Most dyno pulls are done with accuracy as close to possible, above 4-5k rpm and in 5th gear? If this is the case, the only way I can see something credible as showing proof is the AFV function and it's more balanced/closer target being met. I'm all ears for anything that anyone has to offer in addition or in constructive argument...and I don't mean, argue. mm |

Sly is right. About 200 miles after installing the solenoid resister my front wheel started hovering off the ground as I got on the freeway. And, if you start to drive away hard, let off the throttle and get back on it, the bike will stand right up. Before I took off the solenoid the front end did not come off the ground once. It's making more horsepower now. |

Chris & I will get this "back to back" dyno run done this Saturday morning. |

It's making more horsepower now. I also feel that mine is making more power after soleniod removal, though I am not sure how that is possible. Seems that it should just do away with the "kill switch" effect, but the feel is both smoother and more powerful. |

I found that the butterflys were being held back to about 80% by the solenoid and removing them allowed for 100% opening....could this be the reason for some newfound power? Yesterday I had the front wheel skimming off the ground in 3rd gear, 80-90mph. Previous to that in similar circumstances, the front would get light and give a little headshake...but it stayed in contact with the ground. It may be due to various factors (both rider and mechanical) but it SEEMS like some more HP is being produced. See why I am so wary of the new flash. I would be devestated if I got the flash and it hurt performance. |

Fresno, mine was only affected on the bottom end, and it was for the good. I asked about the dyno where I was at, they were going to pick up the mobile one that is shared between three dealers here. I've done the solenoid removal/ $6 part, K&N air filter and the latest flash. It's running like I thought it should have from the beginning now. I'd like to get a decent rumble from the exhaust, just haven't committed to it yet. The sauron is too much, don't like the d&d pipe, or the jardine. The HR1 riot is right up my alley for sound but I'd like to hear the drummer first as well. |

Fresno, that's the beauty of electronics. You don't have to rob peter to pay paul. You can changed the timing, fueling etc under 4000 rpm and it should have zero effect on anything above 4k. |

Yes, in previous assumptions it was thought that the mixture down low would be richened, which of course has a negative effect on emissions. I thought that there might be a tradeoff at the top end in order to get the flash through the governmental red tape. Seems like the new flash is quite the opposite and the EPA would be happy with the improved fuel mileage....and BMC would not have to rob Peter the pay Paul. Makes sense now. |

"Before I took off the solenoid the front end did not come off the ground once." Perhaps the solenoid is actually a safety device masquerading as a sound reducing device to quell the EPA horde. In reality Big Brother is really looking out for your safety and in saving insurance companies around the world, more money. No wild street wheelies and no bikes looped, sliding down the road, riderless. A kinda power governor. |

+ 1 Sly Fresno, Mine has been nearly impossible to get it to come up in 3rd since about the time the AT has been over 60 degrees outside. Sometimes it even has a hard time in 2nd. I really hope this new flash fixes everything. |

I disconnected my noid cable with approx. 200 miles on my bike. It immediately ran smoother from 3K to 4K and also seemed to have more power. Still had a stumble at and below 3K though. Now with approx. 700 miles, it seems to be getting smoother. (using S.O.M.P. dyno). At first I thought that maybe I was just getting used to the stumble and that's why it was getting smoother so I started to really pay attention to the bike. I can say with most certainty that it is getting smoother. Don't know what that means but it's definitely welcome. The low rpm stumble is very annoying. 2ndly, I have a question. I know that this info has been posted somewhere but I don't remember where I saw it. I've read where running the bike at somewhere around 4K for a number of mins does some kind of calibration or something. Can someone elaborate on that? I hope I've explained it well enuf so you know what I'm eluding to. Thanks in advance for any info. |

I have had success with this recipe. YMMV 3rd gear @ 45 mph(4000 rpm) for several minutes to get it going. After the AFVs change a time or two, it only seems to take 3 or 4 minutes to get it to learn again. Prior to trying this combination, I rode a popcorn machine for 1100 miles before it learned and smoothed out. Loretta runs almost as smooth as the 09 CR I rode, when she's running right. Z |

Welp..........I just got home from the dyno....not tooo impressed with the results after the latest flash. Unfortunately I was unable to get a pre-flash dyno done....so this will be my baseline for now. I pulled 117 hp / 72.8 ftlbs The interesting part was the AF values..... First pull (wide open throttle) : 14 Second pull (midrange partial throttle) : 15 looks like this thing is still running lean as fuuuuuuuuu.......I mean fudge. |

Funktron, Did the dyno operator take the A/F sample from the tailpipe exit? Is you bike a CA spec model with factory exhaust? |

Funktron, did you also have a flat spot from 8500 to 9500 rpms? Our dyno results look very similar and mine seems to have a problem in that rpm range. Probably lean. |

you know....I didn't get an actual printout of the dyno (it was free....so I'm not bitching)........but I do seem to remember that it had a flat or even dipping spot in the upper rpm range. The bike is CA spec with factory exhaust. No performance mods what so ever. I did not get to watch the dyno being performed (insurance issue for the shop)....so I couldn't tell you where he A/F sample was from........I'll see if I can give the shop a call manana and ask where he measured from. |

Sylpiranna - I just got off the phone with the dyno shop. The guy said that he took the reading from the tailpipe exit....well....roughly 12-15 inches up. She shoved a sniffer up in there. (If I would have known he was gonna shove anything that far up my tialpipe...I would have demanded dinner and drinks first...but alas....he mentally roofied me) |

Funktron, Is it possible that the CA spec bikes have a catalyst in them and that is why the A/F samples "appear" lean? mm |
