I have used the AEM 30-2310 to translate the signal from the wideband sensor into a single lambda value (voltage). Once you have a simple capture device capturing voltage over time, you can determine the AFR at any point in time. I have used that particular inline controller on several completely unique race cars before, and have been pleased with the simplicity. What customer service is telling you is that your laptop is not out of the box capable of taking that particular input method, that you need to use an external data trap, such as the AEM AQ-1 (I have always done this through the ECU, but I doubt that you want to drop several thousand dollars on that), then download the data from that unit to the laptop.

Proving to my fellow racers that the disdain that some GT drivers have for V6 drivers is unfounded, one results archive at a time since 2013.
