Am I wasting time logging without a WB02? Stock C7 with LT's terrible exhaust smell

[abrrymnvette]

I have a bone stock 2016 C7 A8, only mod is Texas Speed 2" LT's and ORX. Stock NPP mufflers. I have an AEM WB02 sitting here to install permanently but haven't had time. I just did a 10 min warmup and about a 10 minute spirited drive. I'm trying to learn to tune my own cars, am I wasting my time by logging without my WB02 right now? I'm trying to figure out why I smell like exhaust since I don't have cats anymore.

Here's my tune file and log file. I've disabled DOD and read O2's and tried to change the O2 swing high/low to 450mv like I've seen mentioned.

Or am I just stuck with the smell until I break down and put high flow cats back in it?

That fuel smell comes with going catless. It can be reduced sometimes in DI cars, but you're never going to be rid of it until you put cats on the car.

You have a lot of knock retard at WOT and its pulling power out of the car.

Thank you! I'll do some searching on the knock retard at WOT and see what I can learn before I ask another dumb question that's easily answered by search.

He'll want to turn off the cat test too. If you are still using older software look for the exhaust tab in the engine tab section.
