Anyone know a way to code out the cat warmup cycle with PIWIS? I have a Borla exhaust and the cold starts are obnoxiously loud.

its necessary to warm the cats, super doubtful you can eliminate the open loop cycle

I understand the reasoning behind it, but there is no emissions testing where I live so I’d rather have quieter starts. I know this can be done with a tune but I was hopeful there might be a setting buried somewhere in the engineering mode.

I think you need a tune for that. I have done it on my Subarus and it’s a tune.
