But I see they were in reference to the 2011-2014 models. That mod sounds like what I want. I like how it runs and shifts after an ecu reboot and I wish it would stay that way.
So the engine actually seems to hesitate?
How hard does it shift? I sometimes wonder if a really firm shift can trigger a knock sensor-- Not sure how that is set up on those cars, but the higher amount of power going through the trans would amplify this possibility.
It could be sensing false knock, and then R-Tarding the timing a bit.
Although, it is hard to say on these because there is so much crap that can effect it (thts why I didn't get an s197). Sometimes its hard to know where to start.
