http://s4wiki.com/wiki/TuningIf you've read that, read it again. As for the cable. Galletto is good, it works with nefmoto, and it allows you to recover failed flashes (bootmode. Search, figure out how it works BEFORE YOU NEED IT!!!!!!!!!!!). In addition, it can be used with me7logger and vcds lite. HOWEVER! I'd get MPPS (search for MPPS on ebay, they're all the same) as well. It's only another 16 bucks (I say ONLY because to be honest, you'll probably spend more time and money tuning your own car than you would if you paid someone), and also does bootmode flashing. You can never have too many options. As for tuning. Forget about winols, it's got a learning curve that's a bit too steep for a beginner. That, and without a license (you can't get one, you're not a pro tuner, and the price is $1000's) it's more of a hassle than it's worth. Get acclimated with Tunerpro, and purchase a checksum plugin license from MTX electronics. That's all you need to know.
On another note:
You'll find some of us to be a bit abrasive towards new members who ask questions that have been asked, and answered. Look at it from our perspective. Most people come on here asking for free files. Many of them register just to download and contribute nothing. Some of these guys work very hard, and your comment insinuating that a couple hundred bucks was excessive for that work was taken as an insult (albeit not intended as such).
what does you dropping 4k on that have to do with me asking for the correct information? if your so pissed off that people are trying to tune there cars them selfs why are you on this website in the first place?
Let's just let this one go. At some point you may (you will) come across a problem that you need help with. It's best to make friends with some of the more experienced members. I can tell you that snapping back at perceived attacks is a quick way to get ignored (be it right or wrong). This is a very small community, everyone sees everything that's posted. Starting off on the wrong foot (again, whether you were in the right or not) will get noticed. There aren't a ton of guys who's opinions I value, but two of them have posted in this thread
I could write an essay about what you should do, what you shouldn't do, what you should read, who you should talk to, and more. Problem is, it's all been covered before. It may sound rude, but read the forums. All of them. Then, read them again. If after reading you have specific questions, politely ask them. I try to help anyone that has made a legitimate effort. Maybe, one day, (If you stick around, very few do) you can direct our new members to the appropriate places and offer the guidance you feel is lacking.
