Hi,
skeptical eh,
first ...if it is from Chris Corkins ....if he is tencentlife on the Samba..
if it's the same person ...
that guy gets and A+ from me...
and that is saying something as I'm usally pretty disspapointed in many
products and instructions etc.
I'm in dialogue with him on one of his engines, break in oil, oil cooler
fitment, etc. etc. etc...
now THERE is a guy who takes the time to explain things in detail, very
articulate ...
REALLY a pleasure to read what he has to say.......and believe me, that guy
'tries like hell' to deliver some good stuff !
I can already recommend one of his waterboxer engines, I can 'tell' the guy
puts his heart and soul into it.
Most van work, most conversion parts.......all of it , I seldom see really
100 % ..I see 75 % at the most ..
I see bad work on vanagons cosntantly, and conversion parts that don't fit,
and instructions that are lame, etc. etc. like 'all the time.'
as I said, I am seldom impressed, but I am VERY impressed with that guy
and his stuff. He puts total effort into everything he does, as far as I can
tell so far.
and it says on the instruction sheet ..."like the OEM swtich, the vac sw
circuit closes the TB switch circuit when throttle is fully closed , as at
idle or overrun, and also when throttle is opened under acceleration or high
engine load. In the latter cse, the vac sw responds to the actual engine
load, rather than having to to hold the gas pedal to the floor to employ
this funciton.
the vac switch will signal the ECU for load enrichment even at mid-throttle
positions. "
sounds great to me.
what attracts me is that it is sentive to the ACTUAL thing you would want
this to be sensitive to, which is air flow and pressure, where the stock set
up tries do to that off the mechanical position of the throttle plate, and
those get worn ...the bushings etc...
they may not return to zero position well, the bushings get sloppy , the
switches sometimes can't reach adjustment anymore, the switches get all
corroded sometimes...
it is clearly a good example of where electronics can do something much
better than a mechanical system can.
it's my same old thing : - 'where something mechanical and something
electrical/electronic interface, that is a weak area ." ...like throttle
switches are.
just like a MAF transcends the weakness of a AFM ...same here I suspect ...
it leaps right past the limitations and weakness of the mechanical throttle
body switch/es.
I thought you'd really light up and think highly of this device.
I expect it to work well.
the basic principle sounds very sound to me.
