The next time I install it after I get some fresh fuel in the tank I'll gladly post it. But, I would expect it will look like the canned tune on every shipped Predator. If it doesn't, that's a serious problem.

You don't even have to drive the car to pull the tune off.
Simply flash the 91tune, extract it then restore the Original back up.

Surely it can wait a few more days.

I see them.

I seriously doubt all of the ST knock you're seeing is really detonation.

Long term and Short term Tip-in in spark retard along with Torque managment spark reductions, often show up on the logs as ST Knock Retard.

I could really care less if I ever help you.

I'm not sure I understand the attitude. I do have a life outside of my car. It is simply going to have to wait a few more days. If you can't post anything nice...

Fresh tank of 91, still pinging audibly below 2000 RPM at less than 20% throttle, with STKR shooting up to 14 degrees when I hear it pinging. I'm using the 91 octane canned tune, no adjustments made to it. For what its worth, here's my last written tune. It's just the canned tune file that shipped with the tool.

I'm thinking you have a mechanical issue. Theres no way all that knock is being caused by the tune, unless you're using some no name gas, or a crap namebrand. Can you get Exxon, Mobil or BP?

I filled up with Chevron. There's no knock with the stock tune, so I don't think it is a mechanical problem the car.
