What A/F Gauge do you run
Why not? It's a basic tuning
aid.
Innovate does offer a controller for $250. They also have
a simple sensor interface but that comes with the LC-1 pkg.
I told you why not. That unit (as do all wideband sensors) must have a controller, it just may be inside the gauge. So if you got one for that money that does NOT have wire outputs, you are getting had.
My kit, photo of which was posted earlier, does everything that thing does AND is programmable, AND has wire outputs AND costs less shipped to my door.
The kit I got came with O2 sensor, the bung, LC-1 controller, software, and digital display for under 160 bucks.
