[Vwdiesel] Injection pump talk --- ( the LDA and high mileage )

[LBaird119 at aol.com]

So what does the LDA have to do with mileage ? everything ---it works as a 
mixture control 
and will work on all the Rabbits Turbo or not.


  How is that?  I wouldn't say it's a mixture control as it increases fuel 
BUT as air pressure thus volume, is increased.  That would just maintain 
the mixture required for the current status.  More air, more fuel rather than 

same or a little more air and quite a bit more fuel.
  How is a NA diesel supposed to do ANYTHING with a LDA?  It's a bump 
on the log until it gets air pressure.  There's no air pressure on a NA 
so it's sort of like putting a 5 speed shift knob on a 4 speed car.  Might 
look nifty and impress a few friends but it ain't gonna do nuttin for you!

  That's sort of defeating the purpose of having one at all.  The reason for 
one is to AUTOMATICALLY give you more power as it's required.  More 
boost = more fuel = more power.  If you only want a certain amount then 
rotate the cone for least increase, set the spring perch up higher or set the 

stop so that it only moves under close to full boost and then set maximum 
fuel down for no smoke.  Otherwise just use a NA pump, crank the fueling 
up a bit and keep the floor mat pushed up under the pedal until you 
want more power and pull the mat back.  Sort of like replacing a GP 
relay with a push button when you've never had a problem with the 
automatic function of the glow plugs.  Just makes a manual function 
out of something that works fine automatically and you can even 
set it as you like!  :)
