If you don't care to learn the intricacies of say....dwell from your coilpacks, or fine tuning the rate of oscillation from your boost controller, or building a tach output circuit, it is not for you. That being said if you like tweaking every facet of the car, build and wire the damn thing yourself, or you'll run into problems. Its a great EMS, i love mine, but its a very DIY type system. Also, become good friends with an MS guru.

But it is a very nice learning experience and you will become more intimate with your car, than perhaps you even thought possible.
its not like that any more, you can buy a prebuilt box now a days and wiring isn't so bad... Many places can tune it and the software is fairly similar to other EMS programs...
