OBD2 data logging

[RHB]

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.

This is a very nice idea and something you could really get some interesting information over a long period of time. Are you going to make this a permanent fixture or was it just for the fun factor.

This is a tool. It can be hooked up in 2 minutes, and disconnected as easily. I use it to monitor real world performance and specs regarding the modifications I've done to the bike. Rather than rely on someone elses dyno charts or published specs, or static apps like gearing commander, I can record actual data from my bike real time on the road, not on a synthetic dyno environment. But the Tach function is something I can use for reference while I ride.

Wow, what a great idea! It would be great to have a baseline of data taken once or twice a year, every year. Then if by chance your bike starts acting up - getting sluggish, no poor acceleration, etc - you could eyeball the two sets of data and see if anything has changed substantially.

I'm sure a Triumph mechanic would have all the recommended data points for your bike's year and model, but it'd be cool to see a specific set for one's bike.

Can any data be obtained using the reader when starting the bike, such as fuel flow, ignition settings, etc? I'm kind of winging here with this, but I know for a fact my bike starts worse - much harder to start - in the winter vs. the summer.

Good post!

I've only scratched the surface withe the Torque Pro APP. It has unbelievable depth. the OBD2 reader just throws out data from any sensor allowed by the ECU. It is the APP that makes it functional. fuel fol manifold pressure, oil temp, vacuum boost, throttle position and a hundred more parameters.
Torque pro, can graph and log data or you can use it with the accelerometer on your phone to get accurate 0-60 1/4 mile times. video log with selected data projected on screen, on and on.
Keep in mind this ideal for modern ECU equipped bikes, I believe without hooking up the OBD reader, that fuel flow, throttle valve, injector readings are available to monitor. realize you can't change anything in the ECU, just observe and clear fault codes and diagnose issues. Ignition timing is monitored real time as your bike runs, there are no factory base lines provided, all is controlled by the ECU anyway.

Thanks, excellent info and food for thought!
