Most notorious is Innovate LM line, avoid those.

TechEdge wideband also have on-board memory for datalogging, so no need to carry laptop along. To install, you weld on O2-sensor bung like used on autos. There should be flat spot on factory exhaust at 2-1 merge for O2-sensor bung.

Thanks a lot ! I understand what you mean re. accuracy.
