For me, I am also hoping I don't need to order more flex fuel hardware. This gauge comes with O2 sensor, manifold pressure sensor, flex fuel sensor, and the gauge itself can output e% content via 0-5v analog output (needed by ECU). If you're going flex, you need all those things, and they just happen to be part of a nice gauge.
Seb says Ill still need an ECA-2, but haven't seen why Id need that yet. Just FYI. He's also not a fan of the o2 sensor that comes with the gauge.
