yes it would also work on a cossie. there is no difference in lambda sensors.

however, being a narrow band sensor, it's only use is for the ecu to maintain a lamda = 1 running condition under low load conditions.

a narrow band afr sensor / meter is no use whatsoever for tuning, particularly on a turbo engine where richer mixtres are needed on boost. these just cannot tell you accurately what the mixture is.
