What is the current wisdom on the best device to get? I'd probably wire it into my AIM system to collect data vs. using a separate display.

I previously had an Innovate LC-1:

But that one broke. It stopped talking to the PC. Couldn't even reflash the code. Never figured out why. Any advice would be greatly appreciated.

There went my advice! We use Innovate equipment in our cars with no issues, but if you have already experienced issues with the LC-1...

If you've got an AIM logger already I'd take a long look at their wideband controller. Works well and is plug and play with the logger and Race Studio 2. Takes about 10 minutes to install if you've got a spare O2 bung.

My experience with the LC-1 breaking was 3-4 years ago. Maybe they have made improvements to reliability since. The AIM lamda sensor is pretty steep at $399. The LC-1 is half the price.
