OK so I got this crazy idea.
I unplugged the O2 sensors because the ecu was fucking with my tune.
It only allowed WOT tuning... Old news.

The car's tuned enough to boost but its a 'little' rich... and by a little I mean a lot.

Narrow band O2 sensors seem to be reasonable under WOT conditions when the ECU isn't constantly fucking around with the a/f...

My O2 isn't hooked up to the ECU so it can't fuck with the a/f...

So a narrowband O2 would be reasonable for my scenario?

Or am I high?

Flame on!

PS
I understand that the only way to fly is with a wideband, but I have a few extra narrow band stock sensors laying around and i'd like to datalog them for fun if they're worth anything....
