Shameless...A "Tuning" solution would consist a neatly packaged, professient, clean code, and a neatly packaged, easily handled, but yet rugged hardware package that "anyone" can use....and or parts of it..
Not some one-sided opinion of those who can "physically " tune the platform with "commercially" available software/ hardware packages. ..
If one clearly studies the post's from both "tuners" and the amateurs, and or fakes, there are such similar senerio's in which makes up for at the very least 80 percent of the population of the "tuned" group.
Most will never know how this ecu thinks, it is way more complicated tham.one would think.
And without the proper data...ie o.e files, it would be impossible to understand how the calculations work....
Never mind that, from what I have seen and studied, most tunes are missing critical changes in which "modes" this ecu works on...that's all I have to say about that..
