The LC-2 must be pumping a ton of noise across it's ground. I ended up running dedicated power and ground for it, and it seems fine now.

Just something to be aware of. Other wideband setups may be fine, I dunno.
I had this happen with a zeitronix flex fuel controller. However wiring in a microcontroller of mine didn't hade te same result. Anyone know what's up?
