secondary O2 spacer doesn't work good on this platform

It will mess with the A/F#3 correction, unless you disable it, so your cruising and transient afr will be a mess

It will trigger a CEL after a while, even if you disable the A/F#3 corrections, can t remember the code but it is the DTC that relates to "sensor 2 bank1 too lean".. again, unless you disable the DTC (and if ecutek found the DTC in first place)

It MAYBE corrects the P0420 cat DTC, which requires anyway a single click on the tune to be deactivated and doesn't influence anything else


When you disable A/f#3 and all DTCs you can even delete the O2 sensor, so the spacer is useless at this point

Can't help you to find a good O2 spacer, but if you use it, use it temporary because it messes things
