Subject:Stretch update and tach signal?
From:Otmar Ebenhoech
Date:Sun, 13 Sep 1998 21:23:01 -0800

The stretch is running well now (on Gas only), aside from the
diesel gearing (my aircooled tranny blew up). It has over 3000 miles in the
three weeks since it was stretched, it's been to Portland as well as
Burning Man and I just got back from Big Sur. The tranny was replaced in
the early morning on a levee in Davis on the way to BM. :-\.

        It's gotten a name: "Power of two" in addition to the usual "Stretch"

        I tried hooking up the tach signal from the ECU of the 97 Jetta to
the tach wire from the 86 syncro front. It doesn't work. When I put a scope
on the signal into the tach I see a reasonable 12V square wave with a some
noise but it seems that the vanagon tach needs more than that. I know the
vanagon tach is supposed to connect to pin 1 of the coil. Unfortunatly pin
1 on the Jetta coil is not so easy to get to (though I may end up soldering
something in there).

        Has anyone figured out how to make a vanagon tach trigger on a
simple 12V signal like many other tachs do?

TIA
