T6 has 2WD traction control as an option and also does control function like
boost, traction, WOT launch, variable cam, mixture etc in closed loop,
moreover you can tune the P and I terms of all loop controllers directly
from the mapping software if you want to do so. Actually, it has sooo many
functions you can quickly run out of PWM output and/or digital and analog
inputs if you want to implement everything in your car :) For example,
traction control may require as much as four wheel speed sensor, a brake
pedal sensor, a steering angle sensor and an a traction control pot. That's
a lot of inputs for one function. T10 is the solution but it might be a bit
too expensive (around GBP 5500 and probably twice as much for the T10S)

Not sure, however the T6 has various compatibility modes (Pi, Stack...). The
Motec dash may be compatible with one of these, or you may want to change
your dash :) Check out stackinc.com and piresearch.com for more info.

However, I should say that few race engine (at least rally engine) actually
run with knock control. In effect, it has been found that mechanical noise,
such as those caused by sequential gearboxes, can trigger false alarms, no
matter what amount of energy you spend to fine tune your knock control
detection. The pressure gaskets might be a good solution, but I think they
cost more than the ECU (which is still less than most engines but don't be
surprised).
