Best wideband to use?

[DoodieHead]

I have been running the LM1 for about 3 years now and I really like it. I had a grounding problem with the LM1 box not matching the ECU value, but after ripping my car apart I found a ground that makes them spot on.

I have a laptop mounted in my car so I am constantly monitoring A/F ratios and running AUTOTUNE and once the sites are within 2% they really do not move much. Ran a 12.0 @ 114mph on a street tune running 15psi so it must be doing something right.

I would like the Autronic unit, but they are pretty expensive. I was actually to the point where I was going to buy one and could not find one anywhere. Where can you get them? I was having to look for a used model.
