  1. Spaghetti, From my experience, most bikes make their best power when they run an air/fuel ratio of 13:1. When you enable Autotune there should already be some values in the "Target Air/Fuel" table, so you shouldn't have to mess with it if you don't want to. You will probably see values in that table that range from 13:1 in the high throttle/RPM range to 13.5:1 or so in the lower throttle/RPM range. We normally map bikes slightly leaner in the low throttle/RPM range so that you get better gas mileage when you are just cruising on the highway. I've posted some more info about air/fue
  2. This is very interesting to me as well. Below is a list of the things(from the above posts) that you all said that you are interested in: 1. Section times 2. Lean angle 3. Corner speed 4. Available traction 5. Amount the tire slipped 6. Throttle position What else would you be interested in measuring about your riding?...Let's keep this going!
  3. Hey Spaghetti, The answer to both of your questions is YES. Autotune works in real-time, so it will richen/lean the mixture for any changing conditions WHILE you ride. When you go to turn it on(using the Power Commander software), you will see a "Target Air/Fuel" table that gets added to the map. This is where you tell Autotune the air/fuel ratio that you would like to shoot for. You can adjust this table to run different air/fuel ratios for different areas of the map. From there all you need to do is go out and ride. Autotune will do the rest of the work. Hope that helps! Timm
  4. I have mixed emotions about this as well. I recall going to the WSBK race at Miller Motorsports Park in Utah. I was observing both races from the last turn before the front straight. When the pack came through on the first couple laps, I noticed the front-runners(Checa, Biaggi, and Camier) were using little to no traction control as they exited the corner. However, when the last few guys in the pack came around you could noticeably hear the "bup-bup-bup" of their traction control, and it was A LOT. Toward the final laps I could hear more traction control from the front-runners, but it was
  5. Hey Palephase, I agree with Robert. This sounds like you may have a bad or mis-calibrated sensor, or some loose connections in the wiring. You might also check to make sure that none of the ECU wiring is worn through and shorted to the frame somehow. In answer to your tuning question...All ECU's have a "map" in the background that runs the fueling(and ignition). The O2 sensor just supplements this to make sure that the fueling is very well controlled for emissions. On most bikes the O2 sensor isn't even used by the ECU in the higher throttle and RPM ranges. If an O2 sensor goes bad, th
  6. Good question tunnelvision748. The reason why manufacturer's only use a narrowband sensor(and only use it in a certain range of Throttle % and RPM) is because of the emissions standards that they have to conform to. From what I have heard, emissions standard organizations(CARB for example) are really only interested in the emissions of the bike under "highway cruising" conditions(lower Throttle % and RPM) because that is where street riders spend the majority of their time while riding. They want the "cleanest" burn for this riding condition. The "cleanest" burn that they can get is an
  7. Hey Shakabusa, I'm definitely trying to keep the info I post as basic as possible as I know it can get complicated real quick. It's a tough gig for me because some guys have quite a bit of experience with this stuff, while others don't. If you have any questions about anything I have posted, please let me know and I'd be happy to clarify it the best I can. I'm happy to hear you are thinking about going with a PCV for your bike. In answer to your question about the Autotune...yes, if you get the Autotune there is really no need to get your bike dynotuned unless you want to see horsepower n
  8. Hey Laura! I believe you're right about the CAN bus on the S1000RR. I don't think there is a single wire that feeds the RPM to the tach. I believe it uses CAN communication for this. If there is a single wire for this, I don't know what it is. Wrapping a wire around a coil wire for an RPM signal usually works best if you can wrap it around a wire on the secondary side of the coil(the spark plug wire). The wrapped wire around the spark plug wire picks up the change in the electrical field as the high voltage pulse goes down toward the spark plug to fire it. The S1000RR has a "stick coil
  9. Hey Ozzy, A couple things here... First off, make sure that your K&N filter is not over-oiled. Too much oil can restrict air flow, which can make the engine run hotter and also result in less horsepower. You might try changing your air filter back to the stock filter to see if the overheating goes away. This is a pretty common problem I've seen. Second thing...The map you have installed for a Two Brothers slip-on with stock air filter should get the fueling pretty close, but you can adjust the map further if you would like. You can use the Power Commander Control Center softwar
  10. Hey Dan, That location for the O2 sensor should work fine. There are instructions on how to hook up the Autotune at the end of the PC5 installation guide. You can find it on the Power Commander website if you need it. I hope you like the new toy! Let me know if you run into any problems. Best, Timmer
  11. Good points anthem for sure. I'll ask Keith, Dylan, and Cobie what they think about it. Once you get everything set up on the bike, is it pretty quick/easy to do videos? The reason I ask is that we already have to hustle a bit to get the videos done for ALL the students that ride it. It would make it tougher if we had to add more time to that whole process during a school day....
  12. Kruizen - I've never heard of that app. I'll have to check it out!
