OP asked me to call him, I want no part of anything, just know what I've seen.
If you have a doubt about a tuner I wouldn't run them, you'll have placebo issues with your tune all the time because of your doubts. Any little thing and you'll freak out and blame the tune/tuner.
I suggest you find someone you have confidence in and don't question.
In the end though, trust but verify - always datalog your tune from any tuner.

I love my ssi tunes. They feel great I just don't like how all the misfire info is unavailable on my torque app. This has been brought up on ssi's forum but an answer or explanation was never given. It makes me leary since I've already had one motor replaced.

How do i check knock with my SCT device? I occasionally have a few pings with my SSI tunes. Nothing major, only under moderate acceleration, i can hear it just a few times. Nothing constant or continious. Its not enough to worry me unless its doing it alot more that cant be heard.

A few pings not worrying you? Over time that could turn into an issue. Log the situation it occurs and send it in for a look.

Call SCT and ask them if this is possible. They should be able to answer your question. That way you are getting your info straight from the people who make the software and it is not hearsay.

You need to data log, then return to stock until it is fixed. There is a thread on data logging at the top of this page. More than knock needs to be monitor so the tuner can tell under what conditions the ping occurs. More on that is available on the SSi forum and folks will be happy to help.

Well I don't know if I am taking you the wrong way or not but I never meant to insinuate that Shawn was scaling the KR to blow peoples motors. WHAT I WAS TOLD was that he did it to make the logs look safe. I personally don't see the advantage.
I myself have almost 10,000 miles on my SSI tune. Why am I worried about it now ??? because this is the first I have heard of it and though a problem hasn't showed up now, pre-ignition is nasty and left alone will cause problems sooner or later
Have I personally seen limiting ??? NO but close.... I see a consistant KR of 2.5 to 2.8. What I didn't know was if more should be pulled or not. I wasn't sure if this scaling or limiting was proportional.
By that I mean if the original range of KR was say 0-10 just as an example and Shawn had everything scaled to make that range only 0-3 would my whole tune be too aggressive timing wise even though the logs looked pretty safe.
I run timing sweeps, IMEP, BMEP and other combustion tests quite often at work so I am fairly familiar with transducers, and methods of "knock" measurement.
What I am not familiar with is how they work specifically in the F-150. Thanks to a few on here I am getting an idea but will never be an expert or even a novice. I just like to have an idea of what is being changed in my truck

You need to get this fixed. If you can hear it that's very bad. That means that there is "knock" happening that is in-audible as well and happening more often than just the times you can actually hear it.
Just don't want to see you have something bad happen

I don't think you can log it and see anything on those tunes. When I TRIED to run the SSI tune I always got spark knock on light accel. Tried data logging a bit but never left the tune in for more than a mile or two. After 4 months I went back to unleashed.
I had audible knock and when I did data log nothing over 2 showed. My MPT showed 5 no audible knock,unleashed 1.5 no audible knock,5* 10 and off the throttle real quick before something let go and on the shoulder switching out the tune. This is cruising at 60 mph and simulating passing going up to about 75.
Form your own opinion from that and I'm staying with Torrie or MPT

I've had my own opinion. I'm with you, Unleashed or MPT. I was just saying to log what you have and try to get it fixed. If you're not happy buy another tune from someone else or run stock.
