Choosing a Wideband

This is a bit of a minefield. I’ve personally used a Techedge Wideband that  I made myself (back in the day when widebands were very expensive!) - I’ve seen the Innovate widebands too although hey seem to be falling out out favour now.

One thing that many people do seem to agree on, is that the NTK sensor is more accurate than the Bosch LSU4 - so if you see an option to upgrade to it - then take it.

My Current Wideband Shortlist

NGK Powerdex AFX available from BM Motorsports  for $364  (includes NTK sensor)

DynoJet  Wide Band 2 from Hptuners.com $249
