I find the attitudes in this thread interesting.
The last time I checked this forum is here as an information exchange for its members.
I thought we were here to help each other go faster, handle better, brake better, look better, etc.
I've seen quite a few data logs and mine are scattered all over the forum.
That data coming out of the ECM is mine and I will do with it what I please.
That data log gives away nothing proprietary ....there are so may settings, tables, tables that depend on other tables, etc that there is no possible way anyone's gonna figure out the "secret sauce" of what another tuner is doing. I've read repeatedly that there are over 10K adjustments in the fuel tables alone. Does anyone think a 40 PID log is going to divulge anything useful?...NO. It will just give us a snapshot of a measly 40 parameters in a moment of time that are continuously changing due to environmental conditions and conditions present in the motor.
Something else to consider...
I know that in another forum a tuner who shall not be named was found to be modifying/disabling FoMoCo fail safes creating dangerous operating conditions in the pursuit of power. This was found in a log, not by any settings you could see, but behavior of the vehicles during the pull. If you figure out this person, you can also find on his forum website where he clearly states any customer found to be sharing data logs would be FIRED for doing so...hmmm, I wonder why?
Trust but verify has always served me well in my life.
Thankfully none of the vendors here behave like that and personally, if they did, I would question their skillset and credibility and run the other way.
PS-Do not ask me about "the tuner that shall not be named" The information is readily available for anyone to find and come to their own conclusions. Just know that they are not on this forum and I believe our vendors, regardless of who you choose, will keep you fast and safe.
