If you are seriously interested in ecu tuning for yourself, my E46 M3 ran off a motec m600 or you could use the more common bosch 4.3 control unit found in current grand-am cars. You are looking at about $5,000 for the motec with sensors and none of the features besides basic engine duties will work at all and you will have to beg for a base map that is close to your engine so you can even start it the first time.

Data logging with track time is the only way to produce reliable track tunes and the vendors will have to accept less power than the drag/dyno tuners are getting.
