Hagar sez : Hillbilly Tuning is a misnomer ------the TUNING is a highly sophisticated
, scientific approach to getting a Diesel (VW) to perform. ---To your individual
In Hagars case I go for a complete and perfect combustion cycle ----NOT MAX miles or MAX
If you get 43 miles on a gallon ? ----do NOT touch a thing . you are A OK.
But the Hillbilly TUNING was a very complex system --mostly aimed at EXPERIMENTERS or
perfectionist like Gavrik Peterson. -----it is mainly a way of compensating for WEAR in
The normal TIMING system will NOT work if things are worn. ---So what we do is this we
TUNE for performance ----any Performance you like ---BUT you must know how to do it.
This procedure is mainly aimed at OLD Rabbits ---1.5L NA 1.6 L NA and turbos. and it
will do just fine on ECO models.-----If you are a physics type ---you will have NO
problems following these procedures.
Here is a summary of the procedures. : First the FUEL ---do a rudimentary test look up
Fuel 101.---then the Pressure in pump ----those two are the worst of all
problems.-----then we go on to Compression ----and setting of Injectors ---I can go on all
night ----but you must go study diesel Management by Robert BOSCH. ----the Fueling and
idling adjustments are important and ----- one thing I learned from Loren -----get NEW
NOZZLES .----yes old nozzles can be cleaned ----I did it ---but in the tester ? a glass
eye looks good ? JA but it sees nothing.------HE was so right.
Part of Hillbilly tuning is setting the pressure in each injector according to condition
of THAT cylinder.
So if you set them all the same ? --BUT the compression is not all the same ? JA you do
get less than optimum performance. ---JA ? ---bet your sweet ass. So you all see
this is a very scientific way of going about it.-----NO NOT needed if transportation is
ALL you want.-----BUT I Hagar is an experimenter. ----and signing off let me say that
moving the pump or the Fueling screw ? a pencil line ? ---- BULL ---you got to get down
to half a line.-----sure feels good when that Piano is tuned --right on --EH ? -JA
? -----TUNING is a good word ----in a while you can listen to that Diesel ---and you
will know when she sounds happy-----NO SHIT.
I am quoting Feyman -----science --is Observe -Reason-Experiment. ---so Hagar is a
PS : sure like those Feymans Lectures on Physics.
