Anybody try this device yet? Their in house forums seem to indicate that it has problems on motorcycles with reading correct RPM and angular changes (wheelies). If the thing worked it seems like it could give some real world numbers that include wind resistance and air flow to the engine. |

Yes, I tried and forgot to get back to everyone. It would read RPM, but when you would lean side to side or pull a hard wheelie in the 1st to 2nd shift it would freak out and reset itself. |

I saw this mentioned on one of the sportbike forums. http://www.veypor.com Made specifically for motorcycles. Have not tried it but looks promising. |

Capt' - That one looks interesting. I wonder if anyone on the Badweb has tried it. |

So which one of us is going to be the guinea pig? They have software that runs on your PC and you can make HP and TQ charts provided you put in a correct weight for your scoot. This would cut out alot of trips to the dyno for those of us who have fiddle fingers. The veypor is also listed in the Aerostich catalog. Now that would be a real present, Roadcrafter and electric doodad, Ahh ![; )](http://www.badweatherbikers.com/buell/clipart/winker.gif) |

Captjim - I'm sorely tempted. I was also talking to Kevin today about putting a bung in my Drummer's inlet so I could put an O2 sensor there. We would then be instrumented to the point where I could tweak in my Teclusion under some real world conditions and really know what we have. |

How do you plan to read the O2 sensor while running? |

Jersey, why not use the O2 sensor that's already fitted? Perhaps you want to fit a wideband one? |

Captjim - Either with a voltmeter or a "black box" that will convert the voltage to an a/f ratio. Someone told me there are commercial units out there. Opto - I didn"t want to risk altering the signal going to the EFI in any way. |

Jerseyguy- Autozone sells an O2 instrument that will tell you simply if the A/F mixture is lean or rich, my brother has one on his cage. Believe he paid about $49.00. If I remember correctly I believe Sunpro makes it, could be wrong though. It is about 1&3/4" in diameter. Don't know if that is what you need or not. |

Jerseyguy, My understanding is that you can't really do decent O2 reading on the cheap. I understand that you have to use a wideband O2 sensor to get proper readings. Depending on your bugdet, this might be what you are looking for. http://www.hardracing.com/Misc/WideBand.htm |

Cap'- That looks nice but seems like overkill to me. I just need an O2 sensor that has voltage proportional to A/F ratio and possibly a companion meter. |

Here is another similar product. It appears that the wideband O2 sensor is a must, but perhaps not all the other bells and whistles. http://www.innovatemotorsports.com/products.php |

Yep, I've looked at that one too. I think what you want to stay away from is autometer type gauges as people tell me all they do is bounce around. I definately want something that will do data logging. |

I'm beginning to think that the A/F meter is a better place to start than the HP/Torque sensors. Having both would be optimal of course. The videos on that site are quite informative. I can see me tweaking in my Teclusion to get the optimal, say 13 or so A/F ratio With the Innovative box. I'm thinking we can simply put the sensor up the tailpipe. They suggest that would work OK under load. Have you run across any other brands? |

Those two are the only ones I've seen that look promising. I agree, for tuning, the a/f meter is the best choice. |

This is a good post! Those two systems are what I was getting at when I asked how you were going to read the sensor. The capability to log the A/F as a function of RPM seems like it would be very useful. I am not that familiar with the Teclusion box. Can you add/subtract fuel at different levels corresponding to the RPM range? That would be just like a custom map minus timing changes. You could really smooth the power curves out on your own without a dyno. |

The Techlusion box has 4 pots on it. It can only add gas & not subtract any. The pots correspond roughly to idle jet, main jet, needle and accelerator pump on a carb. I've opened up the intake and exhaust on my 9 and I suspect that I'd never want to have less gas (I could be wrong). Dynojet has a similar product. I think I'm going to write Innovative and tell them what I plan to do & see what they say. (Message edited by jerseyguy on December 21, 2004) |

Here's some interesting stuff for you Jersey, just some background info, similar to what you want to do but with the narrowband sensor. The wideband sensor is a good choice though. http://www.badweatherbikers.com/buell/messages/3842/16109.html It will be interesting to read the a/f ratios at cruising as well as WOT. Here's a link to an O2 sensor display I fitted to my bike running off the stock sensor... http://www.badweatherbikers.com/cgibin/discus/show.cgi?tpc=32777&post=258502#POS T258502 |
