I am a pretty smart guy but teaching myself to "learn" a computer, (which is what you are trying to do, somewhat,) is near impossible without ALOT of time spent.
That is one of the reasons for having someone that does this on a regular basis and knows what they are doing, do the job. I have been down the same road you are on right now many times. Finally came to the conclusion that it's FARRR CHEAPER to have an expert do it for two main reasons.
1. All the crap going on in my life doesn't permit the cost of time loss/ gain in the endeavor. Plus, I am always second guessing myself if I have everything in correct parameters.
2. One little miscalculation anywhere in the set up or drivability can be disastrous. It may act and drive alright but really isn't. Setups that took me weeks of studying and work led to bad outcomes with thousands of dollars flushed down the shitter. :violent1: So, not only did I loose time in the study aspect but also monetary repairing some things that would have only cost me a few hundred if I hadn't been a stubborn stingy fool who thought that tuning isn't that hard, I can do it, anyone can...............
One more thing, tuning a car to get the most HP out of it is an art. But realize it is tuned to the nats ***, no room for error. On a street car, this is stupid. One tank of bad gas and the engine is junk. Saw this numerous times.............
Just putting out words of wisdom here. Not saying anybody here can't teach themselves how to tune a car. I am just saying, don't fool yourself into thinking it's not that hard......
Oh, and don't forget drivability. A lot of people just tune the dyno, bad idea.
Hope this helps. :D:cheers:
