Edit - Question - I just finished installing the gauge and im having this problem. The gauge is constantly flickering on and off. Anyone have any ideas?
I was also wondering how come its not possible to use the stock 02 connector for power, ground and analog? Its powered on ignition and im sure the its grounded to the same as the stock ECU is.
My main concern is just wiring that 1 analog wire that i will have to send to the stock ECU to keep it happy, is it possible to send it this using the connector?

I recently installed an LC-1 in our 1997 and tried to have it emulate the stock O2 sensor. It just doesn't work. After a lot of frustration, I took the car into an exhaust shop, had a new bung welded in, and put the stock O2 sensor back. I am now running both sensors (three total in the exhaust system--stock front, stock rear, and the LC-1).
Innovative claims that the LC-1 can emulate the stock O2 sensor in their advertisements, but their message board tells a different story. In my case, I just couldn't get the output adjusted to the range that would always keep the ECU happy. It would be good for a while, but would cause a CEL after a good drive. The only way to clear it was to pull the battery. That got old fast.
If you really want to try it, use the 4 wire O2 sensor installation document from Flyin Miata and the wiring diagram for your year Miata, http://www.madracki.com/miata/wiring.html. If you want to do it the easy way, though, spend the $30 to get a new bung welded in.

Problem fixed - I hooked up the purple wire incorrectly. Does anyone know where i can hook up the gauges illumination wire? it says not to use the dimmer.
