The "problem" with the SMT6 is that it is NOT plug and play. Just because you bought it, doesnt mean you are going to be able to successfully tune it, much less install it. At the minimum, basic knowledge is needed of how a vehicle is wired, how a MAF/MAP works, and so on.

Base maps are base maps, generally with ZEROs and just set up with the global paremeters setup so the vehicle will start. Sometimes premade maps will work with your car, but more often than not, they need tweaking.

One of the beautiful things with the SMT6 is that it can be wired in and controlled many many different ways to control so much. But that also makes it a serious handful. Basic information inputs used are TPS, MAF or MAP and RPM. Thats 3-4 variables. Now you can also add, for tuning purposes, Engine temp, Watertemp, Exhaust Gas Temp, Intake Air Temp and anything else that runs on a 0-5/0-10 volt output. You can't use them all, but you can use them in different configurations which can get damn confusing.

Unless something was screwy, ALL the manuals and basic wiring diagrams are ON the CD.

Tuning your own vehicle is doable, but just because it can be done, doesnt mean you are going to be able to. The more crazy the mods are, the harder it is going to be. Bigger injectors, bigger MAFs, boost on an NA ecu, are all tough nuts to crack. No wonder almost all piggybacks and standalones are sold only through tuners that tune them. The SMT6 gives you the option to skip the tuner, but also gives you the option of a huge headache.
