well.. define "real" traction control.

while you're correct that it isnt an ideal traction control, it does skirt the rules that say you cant have wheel or axle speed sensors.... its really a simple solution to a complex problem... while it wont provide the IDEAL traction that a true closed loop system provides, it is a nice open loop solution to minimize your wheelspin when you do break em loose.. or maybe just limiting you from the edge of being loose and ultimatly getting more consistant (if slower)ETs...

but im curious to hear the definition of "real" traction control, esp when you HAVE to use the MSD box.

I'd love to explain it, but I'm not allowed to, it's proprietary information. But no, it does not involve wheel speed sensors. It is a true form of traction control though. It works wonders for cars with 3,000 HP and a 10.5W tire when you're on a hot track.

Real traction control MUST use wheel speed sensors to determine slip ratios of wheels. If you dont have a closed loop setup you will only be 'guessing' at what the wheels are doing. You could be cutting power before you slip or you could be cutting power too late... Both situations leave some acceleration "on the table". If you want to get really complex, combine wheel speed sensors and accelerometers to create algorithms to determine appropriate traction

This is used in conjunction with a spool since you are not talking about using wheel sensors.

I'll stop there. Not going to pry you any more.

No, it's not done with a spool.

my bs3 you can use the factory speedo sensor input to run it's traction control.
