I began some data logging with my WIFI OBD2 device stuck under my seat, I really only scratched the surface with what is possible, and its been raining this week so no further fun yet. But I did data log R.PM and speed on a very short suburbs to just outside town ride.I used a 10 dollar WIFI type OBD2 reader ELM 327 from Ebay and Torque Pro cell phone APP. The connection is easy to establish and solid. I just tuck the reader under the seat establish a WIFI connection, mount the phone to the handle bars and go, you can switch between several user configurable screens, and if you activate logging, all data will save to your phone, or you can upload to the Torque server. I mounted my cell phone between the handle bars and displayed a nice big fat Tach readout, I now have a usable tach if I want.
I ran the bike hard to redline a few times and that means Rev limiter. BTW stock red line is 7000. the rev limiter cuts in at 6880-7030. depending on the gear differences due to varying degrees of overrun
Anyway The OBD reader works using Torque Pro App which combines GPS readings for accurate speed calculations (or you can simultaneously use OBD KPH and compare results), and OBD RPM data. Very cool. Second gear rev cut @ 6880RPM 101 KPH (63 MPH). Third gear rev cut @ 7030 RPM 129 KPH (80 MPH). I'm running a 44 tooth sprocket. Charts below. I made these up in EXCEL from the raw data tables, but I now have an extension that graphs any number of parameters as you ride.
