Don't know why they pulled these. I was down there a few weeks ago and they
were still selling them. Not for $230 though... I believe the price was
$695/exchange. I know for a fact it was $600+.
Cheers,
Jeff

Ah... interesting. I asked them about this at SDM07. During the course
of development of our AFM/MAF translator, we discovered after the
second rev that our entire approach was wrong, wasn't going to work,
even though it appeared to and would actually work most of the time
which is what lead us down that path to begin with(and explains why
they have a few people running them, apparently fine, I wonder if all
the people that tried them had them working ok). Perhaps they've hit
the same issue.
The split second maf translator that they were using shouldn't be
capable of doing the translation correctly according to what I know
now, as it functions just like the early boards we made. We have
Boston Bob's buddy george thinking about how to pull off the new
design. But man if they can get it working for $230.. that's awesome.
The split second maf translator retails for like $339 alone... and the
Ford MAF sensor they use isn't free either...
The upside and downside of their design has to be to put it in the
original airbox, great for flying under CA smog radar just like their
stroker motors, but you don't get the real benefit which is ditching
that airbox and that nasty nasty elbow. On the dyno with the early
boards and focus MAF we saw 10-12% gains in HP and torque when we
pulled that old airbox and elbow out... since it caused a 1PSI
depression at 5k rpm... 1 PSI!!! It's like adding a turbo that boosts
to 1PSI just by removing that mess. Only problem is the intake
resonance causes a mid-frequency hum which was also a PITA to
remove(which lucas confirmed with me they had when they tried it sans
airbox too). We lucked out and stumbled across an intake design that
kills the hum... I welded up an aluminum intake piece just to get the
ford maf onto the intake, get the breather and IAC plumbed in, and
test the first boards. But as it turned out, it was just the right
length and configuration to kill the hum... talk about serendipity..
it would have taken me days of reading and hours of mistakes in math
to even come close to getting it right on purpose ha.
