Has anyone used this with their CBR250R yet? I have been reading a number of favourable reviews of the Dynolicious app ($12.99) which is a performance meter for the iphone and ipod touch that utilizes the accelerometers native to these devices. Below is a link to a YouTube video that provides some details about Dynolicious.
You have to configure Dynolicious before the first run by inputting a few pieces of data related to the bike and the figures you wish to obtain (e.g., total weight of the bike and rider; decide whether a roll-out will be used; decide whether you wish to have an estimate of crank or wheel hp, etc).
I decided to try this device on my CBR150R, as I just received a fuel-programmer for it and wanted to obtain some stock performance figures. I know of an isolated paved (and flat) roadway in the middle of the nowhere - that is virtually empty of traffic and void of any homes. I ran a few runs there to test out the device. One issue that I ran into immediately was that the results kept indicating the CBR150R was reaching 10 mph in about 10 secs. I knew this didn't make sense. The unit may be starting because the vibrations from the bike are setting off the G meter. I will have to take a look at that.
I ran the bike through the gears and recorded a few runs. Unfortunately, after each run the app detected an error (this may have been due to slight movements of the ipod touch inside the clear plastic sleeve of my tankbag). However, the runs still remained relatively consistent. I have since purchased a skin with an armband for the device and hope to try tethering it directly to the top of the fuel tank (perhaps with some foam underneath for support and to reduce vibration).
If I can't find a way to get Dynolicious to record consistent times that are free of error warnings, I may spring for a GPS performance meter. The best (and most affordable) one I've found is the Performance Box.

I saved the run below, as it appeared to be representative of the kinds of results I was obtaining. With that said - there were still errors in the pass so the results are really only tentative until I can find a way to produce a clean run. One pass yielded an 8.0 second 0-60 mph time, but it recorded my top speed as 90 mph (which I knew was false) so I just discarded the results.
CBR150R: Outside Temp: 10C Wind: small tailwind
Modifications: Full Giannelli performance exhaust, K&N Air Filter, intake snorkel mod, 14T sprocket.
0-10 mph.....1.58 sec
0-20 mph.....2.54 sec
0-30 mph.....3.69 sec
0-40 mph.....4.95 sec
0-50 mph.....6.60 sec
0-60 mph.....8.41 sec
0-70 mph.....11.05 sec
0-80 mph.....15.51 sec
1/4 mile 17.10 sec @ 84 mph
Peak HP 22 HP
I set up Dynolicious to assume no drivetrain losses - which helps to explain the slightly high hp figure. There seems to be some slight deviations in the hp figures after each run anyway, so that should be factored in.
