JDM 2JZGTE AFR's

[MrOizo]

Does anyone know what the AFR's are for a Stock 2JZGTE (JDM) without a CAT?

In New Zealand, they have added emissions testing to the certification process for engine conversions and we only test for AFR's and not the make up of the gasses.

Cheers,

I run a Aristo ecu on my car ( 1jz head/2jz bottom) with aristo 440 injectors and full three inch exhaust inlcuding the downpipe.
I was seeing fluctuations between mid 14's to mid 15's on the wide band. I know its not your exact setup but something to compare to.
