Hi jim,
What do you mean by " We only have 27 wires in the main harness for either
implementation"

I don't think you mean there are only 27 wires on the Focus ecu. That
wouldn't make sense.
 A subaru ecu has about 60 or so wires.  Tdi roughly the same, maybe it's 45
to 50..
This soobie ecu next to me has 84 pins I think, but not all of them are
used.

Wow someone brings up complexity.. good good.  No you're absolutely
right adding more thing increases risk and increases the chances of
failure. However the zetec conversion itself is so simple, that adding
what we need to offer outstanding power to weight and great power
levels STILL keeps things simpler than what's out there.  That's the
arguement for having both power adders. The turbo is more efficient,
but comes at the cost of simplicity.. there is another cooling system
for the intercooler, and there is more intake plumbing, and there is
an oil feed and return. The supercharger on the other hand while not
offering the same output levels of efficiency of the turbo, still
offers great torque in the low end because it's a positive
displacement blower, and doesn't have any additional oil lines intake
plumbing etc.. just an extra idler and longer belt, both still widely
available.

 We only have 27 wires in the main harness for either implementation,
how many in the R-TDI? Scott how many in the subies?
