The MS might be good and flexible, but it sure seems like a time pit...
And I don't think I'd like to move it from car to car - I think one
time will be more than enough for me...
I'm pretty happy with the stock system, as long as it works, because I
can always take it to the garage if I can't fix it or too busy. A
custom system rules this out.
Installing a new system IMO is actually attempting to develop an
engine control system on your own and tuning it, even if the basic h/w
(electronics boards) is working. Adapting to current sensors, problem
solving and optimizing usually requires a whole team at the factory,
and I don't have that kind of experience.
Nope, not for me...I'd rather spend my time camping...:-)
MS is probably for those enjoying playing a lot with the engine and
squeezing more performance out of it.
But I salute all those who try!

Cheers,
TM
