Default LC1 Help

I have tried to install my LC1 with dynotune gauge on my car and it keeps flashing error code 8 saying the sensor needs to be replaced. I bought a new sensor and tried again but still the same error. Anyone have any thoughts?

I had the same problem. Changed sensors and it worked for a little while and came back. Are you connecting this thing up as a narrowband too? I welded another bung in and wired it up as just a wideband and has worked fine since.

Yep....There's two grounds that need to be grounded together and there's one that needs to be grounded away from them...Make SURE that they are properly grounded... Scrap away all of the paint wherever you're going to ground it and make sure that it's bare metal...Good luck

The bigger blue wire, the heater ground, I would run it thru the existing passenger firewall connector (Pass lower kickpanel) to the back of the passenger side cylinder head by it'self.
