www.shiftmaster.com has a small board that hooks up to the service port on the car's processor and then you hook up the other end to a laptop.
you can change ignition timing, air fuel ratio, fuel pulsewidths, fan turn on temp, shift points, rev limiters, speed limiters, egr control, filter out check engine lights, mass air function....and about 400 other things.
it's all there, the whole entire processor is mapped out..there's even a GUI that will display 3D graphs based on x/y/z..spreadsheat control so you can enter in formulas...etc
you make the changes according to the modification's/data logging(with Autotap or wideband o2) you've done and click download..put the laptop away and drive off...
it's actually not that easy to tune a car yourself..you still need to know a TON of internal EEC-V information..formulas, encoding..etc..but there's a great source of info on the EEC-TUNER group on Yahoo.
i've managed to dyno at 255rwhp at 5500 rpm and 254RWTQ at 4600 rpm with my 97 V6 Mustang! running a vortech supercharger at 11psi, 36# injectors, split port heads, 80mm lightning maf..
among many other things$$$
all i can say is that the eec-tuner is a wonderfull tool, my car would have not been running without it...it's been around for almost 3 years....
