Advanced Auto was $56 for LSU4.2 (Bosch).I did not need mine after all since after checking circuits I found a shakey ground.My wide band is rockin' again.Advanced Auto was very good about taking the sensor back as well.

That's great!  I think the LC-1 may be more sensitive to ground issues than some of the others....A good engine ground is the safest way.  Also, it is important to put all the grounds to the same connection as it seems to get screwed up if there is a grounding differential caused by using a couple of different points.

You are 100% correct about grounding in close proximity.I don't think "stack grounding" will hurt either as long as your ground is clean and solid.In my case I had the ground lead slipping out of the one connector that I forgot to solder.I'm thrilled if stupid stuff happens in the garage rather than at the track.

LOL...I believe in solder...If I recall correctly, I soldered all the grounds into a single terminal
