What do you use for data logging your MINI?
As part of having an ECU tune put on my car, I've been looking for a way to do data logging with a good data rate. What do you use for data logging your MINI? Here's what I've been trying thus car, using the OBD port…
For in-car "dashboards" I've had good luck with Vpeak wifi and Automatic Gen 2 Bluetooth adapters and iPhone running OBD Fusion and/or DashCommand. The problem is, while 1-2 updates/sec is fine for a some gauges on the dash (I'm not racing or autocrossing, just "spirited" driving) … that's not nearly enough to see what the engine is doing during, say, a 2000-6000rpm WOT pull, which is over in a few seconds.
My current set-up is a USB OBDLink SX with MacBook Pro. I've been trying various apps for data capture; the best (so far) are Palmer Performance's Scan XL and OCTech's OBDwiz for Windows, or EOBD-Facile for Mac/Win (designed more for diagnostics than data logging though).
No matter the software, I'm getting 20–-25 PIDs/sec max. This means I can either capture a few datapoints at moderate resolution, one at great resolution, or lots at lousy. At this point I think the limitation is the MINI's OBD implementation; it seems to have a pretty consistent 35–50ms response time.
I'm looking for something that will provide a decent data rate for the core PIDs a tuner needs to look at. I'm hoping to avoid spending $300 on a RaceCapture module; it looks great but I've already blown through my car toys budget for the year. And I totally don't have the time to write a CAN bus sniffer.
Thanks!

Allot of this has to do with how much money you want to spend and what you want to to log. I used ISTA that I have on my laptop by recording a portion of my screen with another program. I also used the "EngineLink HD" app. The time period between readings is not the best. I have a Ultragauge now and it actually appears to function faster than either of the two previous but then you are not able to go back to review the data.

I use an OBD2<-> Bluetooth adapter and either Torque or Race Chrono on my Android phone. I can get multiple PIDs at 4x/second no problem. Not good enough for tuning but I'm not doing that - just recording track sessions and quantifying intercooler performance, etc.
