Title: O2 wideband sensors
Post by: daveismissing on June 24 2019, 07:50:21 AM

One of our Eurobros posted (FB) this Ozzy gent saving an AJ Foyt Buick engine. Was a good watch.

Interesting tidbit he threw out was that the NTK wideband sensor (while more robust) is slower than the Bosh LSU

NTK makes three or four grades of sensors.  Did he say which one?

Just a visual - interpret it as you like.
NGK vs AEM. It's like apples to oranges two different cars but it's the same logging hardware. The AEM updates faster but it bounces around like a jack rabbit, the NGK gives a nice stable reading.

I made it to the two minute mark before I had to turn it off.

  It's also interesting that Buick had to make them for homologation rules and offer them on street cars as sort of a COPO option.....

....and they only came in cast iron.
