James, I had this problem on one of my customer's vans.  First you need to
set the "Basic Setting" and timing via a 1552 tool or emulator.  I have
these for rent if you need one.  Rent is $75 for 10 days and a $100 deposit.
If that doesn't clear up the problem then it could be your fuel pressure or
injectors.  The customer had a similar problem and it was finally resolved
when we went to 1.8l Jetta injectors, fuel pressure regulator and A2 fuel
rail.  I have these together in a kit form for $278.60.  It includes new
Bosch injectors, new Bosch Fuel pressure regulator (higher psi than the
waterboxer regulator, but stock for the Jetta engine), a new plastic fuel
rail (VW) and clips for the injectors.  Why put old injectors or fuel
pressure regulator on a new engine?  Why put Waterboxer parts on a Jetta
type engine.  Put these on your Tiico and have all new and all correct.
Just FYI.

Thanks,
Ken Wilford

Subject: TiiCo - poor performance on cold start up, any tips ?

I have recently had a TiiCo engine put into my 90
Vanagon GL.  It has quite a problem with hesitating
and stalling when the engine is cold.  I have to drive
10-15 minutes for this to really stop being a problem.
If it is performing so poorly now in the summer I
expect that I won't be able to drive it in the winter.

I was told by a mechanic that there is a place on the
engine for a "preheat intake" - something which would
help atomize the fuel when the engine is cold.  He
said that there was a place for something like this
but nothing was actually hooked up on my engine.  Does
anyone know anything about this ?  Or any other
suggestions which would help alleviate the
hesitation/choking at cold temps and low gears that
I'm experiencing ?

Thanks in advance for any information or feedback.

-James
