I followed thgis with great interest since I'm in the process of buying a
1991 Jetta with 1.6 TD. Mine has a hose from the turbocharger unit to the
FI pump. I assume this is for the fuel enrichment system?
My big question to you is. What means LDA???? How do you turn it on and

" Bunny Bondo " is a cutie VW -- Metallic light Blue 4 door 1.6L Turbo
(Garrett) 1984 Mag wheels
No she did not start out as a ECO . BUT for the last two years ----
ECO every mile ---or should I say every
happy mile ?.
I did NOT know about ECO's when I started to Hillbilly Tune her.
After about a year
of super performance ---- I found out that VW did the same as Hagar.
With a bit
She goes 900 miles on a feed. ( 42 Litres ).
Possible mostly with help from this group. ----- The way I remember
the ECO explanation is like this
ECO does not stand for economy --- has to do with pollution.
VW was faced with loosing its foothold in USA so they took the LDA off
the turbo 1.6 and
added a cat. Like I have been saying for some time ---the VW 1.6
thrives on lots of
manifold pressure. ---- lots of vortex and swirling gives a good burn.
And opening that intake
valve at 5 psi overpressure is different --- than opening it at a slight
Furthermore the way I understand superchargers they heat the ingoing air.
for a better ignition.
I did NOT remove the LDA ---- I just made it avaiable on command .
Here in BC Canada we have a few little hills where the LDA comes in real

flick of a switch.
When I got snared by her she was a wild one ---I guess about a 100 HP and
clouds of smoke.
After a lot of TLC ----wow she became a real pussycat. type Bunny. No
smoke NO slipping the
clutch (a la James Hansen) ----but driveable -----very driveable. Just
love that thing.
She drives like a sportscar ---50 psi front tires ---- NO power steering
When I got her the Turbo hardly moved ---- but a year later running her
extra LEAN ?
the thing cleaned itself ----and she sure howls now ---so now I will NOT
have to clean
it. ------------- a Turbo working 20 years ? ---thats is no
chickenfeed. KIlometers on
clock ? getting close to 300 000.
When Ferguson came in here --one of the first things he mentioned was how
turbines are to gook on the blades. --- This proves that point.
