Tune & Emissions Test
Seriously considering adding a tune to our 2014 CLS63 S, but here in Ontario we have biennial OBD emissions testing. Has anyone with a tuned CLS63 undergone OBD emissions testing and had any issues (or passed?)
Want to make sure I'm not spending thousands of dollars only to have to pay the dealer to flash the car back to stock for an emissions test.
Thanks.

I have passed with a tune and deleted Cats..I dont know if there is different testing protocols for each state..Meaning where Im at we only need to have one monitor turned on, active, and good to go...

Tune only will not be an issue. if you have catless down pipe and the rear o2s turned off in the tune you will probably fail. In Oct 2016, they changed it so you cannot have any readiness monitors in pending state. Disabling them in tune, will show not ready for that test....unless you have a guy....

^^^That is not per my state. I just did my yearly smog test 3 weeks ago. Passed with flying colors. But none of my monitors were in "pending" state. They are turned off except one.
Side note, I love your mod list!

I have a supercharged Mustang with an aftermarket tune, all of my monitors except "Comprehensive" are set to N/A which passed last time but I have heard they no longer allow that to fly.

Thanks, so most tuners will leave the monitors on then unless requested otherwise? Looking at a Eurocharged tune specifically since they are semi-local.

Quick way to check would be to get a cheap ELM 327 bluetooth OB2 adapter and the "torque" app and run the emissions status gauge. If its clear there, you will pass.
