Believe me, your time is not worth the 50 bucks you could spend on a high end equalizer like the rayspeed unit. By the time you figure out what resistor goes where, how to wire it all up, blah blah blah, you could have been doing some racing or wrenching on your car.
I love doing projects as well but you have to know when it's just not worth the effort for something that others mass produce and most likely have a much better design.
