hi Karl.
sure, 'yes' on both.
I installed the electro/pneumatic TPS unit ..
on one of his engines. ( more below on that ) ..
My first thought on that unit ..
that it senses idle position of the throttle plate by measuring air
pressure/vacuum ..
and responds to that .........and that has to be far superior to depending
on a mechanical switch ..
considering that throttle bodies wear, that the mechanical micro switches or
their mounting can wear etc. It's using electronics to transcend the
limitations of mechanical devices...always a leap forward.
And installing one of Chris Corkin's 'better waterboxer 2.2' engines I
emailed with him a bunch.
The guy is one smart dude in my opinion. I am seldom impressed ....but I am
with Chris..
articulate, gives excellent directions, for example, on installing his oil
cooler kit ..
I can tell he really gives it 200 % effort.
the engine was just perfect. Flawless even.
He's thorough about break instructions and break in oil..and so forth.
About the electro/pneumatic switch.
On this particular van and engine .........
part of the story is that this van was a rusted to near death 91 Syncro
.....needing just 'everything' ....
so 'most' parts on it ......were either missing, broken, or just very tired.
I put the original throttle body back on.
Oddly, the air bypass screw on it had minimal affect on idle rpm.
The pneumatic switch seemed to be working, there's a small red LED on it
..showing it gets power.
the van idled well enough ...
just didn't seem to respond to the air bypass screw...both before I put on
the gizmo and afterwards.
Whether that throttle body was faulty, or clogged, or whatever I didn't
find out - the van needed dozens and *dozens* ( ! ) of things done to it
just to be able to install engine and trans ..
so feeling like I put about 50 extra hours into it I wasn't about to go
digging in yet another system or part , since I'd already given away so much
time on that job.
I asked Chris about the idle...if he had any thoughts.
It 'sounded' different to me too.
it also had new Dune Buggy/racing type headers on it .........thought that
might be a factor in the idle quality or sound.
He told me that VW uses a cam that gives a nice idle, and that he uses a
cam that has a slightly different cam profile ...........that gives less of
an optimum idle but a nicer power band.
It idled just fine .
but not like a stock waterboxer quite.
and it ran very well. 'Bout the best waterboxer I've ever driven.
As far as I could tell, the idle switch gizmo worked...
and Chris is a super meticulous engine builder, and his engine is 'The'
enhanced waterboxer engine I recommend these days .........the only one
actually.
