Hater-ade? You fail to acknowledge the elephant in the room! If your auto parts counter person invited you to perform sexual act, chances are that you would move on! Unless you are into that sort of thing? There is a thread on this forum in this topic section titled "SSI Warning". It is locked, but not deleted. It has over 3,000 views. Why do you suppose that is? I gave Shawn the benefit of the doubt once. It is up to him to meet half way and thus far he has failed! Where I grew up, if you broke it, you fix it!

Guys,
Question for you about the SSI tunes. Now I am in no way trolling or trying to start anything here, just on a fact finding mission.
I am currently running the 87oct. T4 tune in my 2012 eco. I have expressed my feelings about the difficulties I've had with Shawns customer service, having said that, He still puts out a damn good tune. End Disclaimer
Now my question....have any of you guys ever heard that Shawn "scales" the amount of knock retard to make it look like it's less when we look at the logs ??? I called MPT to order a 93 oct tune with race trans tune and talked to a guy there about what I had and what tune I was currently running. I told him that I data logged my current SSI 87 tune and that I am only seeing about 3 degrees of knock retard and that's when he told me that he scales them so it looks much safer than it really is meaning that a KR of 3 degrees could really be 6 or 8 or whatever he sets this scale to. Sounds fishy to me but this guy also told me that they have seen "quite a few" SSI tuned trucks with "blown motors" due to this tactic.
I know a good amount about data logging since my job involves gathering engine data like this just about every day. What I don't know much about is whether this is possible to do in our trucks.
Now like I said, I don't want to start a debate about MPT or SSI or any of that crap, and I especially don't want to sound like I am throwing MPT under the bus. I am only asking if you guys have heard of this or if it is possible to do it

If max knock count visibility was set to 10, would it make you feel any better?
Take a look at this picture. If Mt. Everest's peak was covered by fog and not visible from the base, is all of a sudden the mountain shorter? No. The mountain is still 29,000 feet high.
If you datalog your truck and you see a "chopped off mountain," you might want adjustments. I would want adjustments if that was my "street tune."
I think people are falsely correlating knock sensor sensitivity and knock count.

Is this a common practice among tuners?

If you can't datalog, how do you know what knock you're seeing?

Call Shawn.
He'd most likely 'splain his tunes without giving away the farm.

Maybe I should sign up as ymeski56 over on the SSI Forum & ask.....
As a moderator, I can't wade into these threads too deep, but personally I would be interested to know what's up w/ that. Never seen knock hang a hard right at 2.99 before... possibly it's proprietary info & we'll just have to keep guessing/ wondering. Additionally, if he's not tell you guy's, he sure ain't gonna tell me.

Meh... water's warm. 
Yes, there is proprietary info to the tunes, but there is also more to a log than just KR. The real-time interrelationship between KR and one or a couple of other things tells the story - assuming people know what they are looking for.

If you're saying you saw "riding the knock senor and having lean afr" data logging your engine, why did you continue to run it that way? Pull the tune!
