Thanks Dave W.

It's this thread, your posts, #5 and #15.

I'm interested in your use of the ECM as a way to use WBO2, as I'm about to purchase either a BURN2 and Ostrich 2.0, or a APU1. I'm leaning towards the lower cost BURN + Ostrich, especially if I can use the ECM for a future WBO2 sensor. Thank you for sharing your tools an expertise on this forum!
