what type of management if its chipped ecu just disable o2 alltogether.

bennyhonda7

true but will it still read my narrowband afr?

Chris Harris

not if you disable the entire o2

try just disabling the O2 heater

but my guess is you have something else going on...just an O2 heater code wouldnt rev limit you at 4k
