I am all for getting others involved in DIYing, but Tuning is a whole different game, it is way to easy to screw up and then you will be cursing that cable and software as the tow truck piggybacks your car to the nearest dealer for a $1500 ecu replacement.

If the tuning guide is over your head, then please for the love of your car leave it to the professionals.

From my 2nd hand experience, this place is the best for open source tuning. Xtreme Racing Tuning ? Viciously Tuned, Driven hard

Understand it is still possible you can brick your ecu and be towing it in for that ECU replacement, so follow the instructions to a "T" and get an extension cord for you laptop, and battery charger if you are iffy on that as well.
