In all reality it is a crappy option now a days. All it does is allow you to run speed density. There are only 2 injector chips for it I know off 550 and 650's. you will still need a AFC or GCC to tune with which is a crappy way to tune fuel as you aren't adjusting the fuel table at all. And then a ITC for timing.
Yeh 10 years ago it was great as there wasn't dsmlink v3 that allows you to run speed density with full tuning of fuel, timing and air flow tables.
But it is kind of cool to even hear one talked about these days.
