300Tdi Diesel pump tuning.
Disco_Dennis:
Hi. I've done a search on here, but I can't find anything. :?
Can any one tell me how (or direct me to an appropriate thread) to turn up the diesel pump on my 300Tdi? :huh:
(pics would be nice... too [-o< )
Thanks,
Dennis.

That's adjusting the idle speed and timing IIRC?

thats how to slightly adjust the timing, why you would want to retard the timing beats me????
normally advancing it slightly helps but generally i wouldnt bother,
diaphram cap off & turn the diphram 90degrees clockwise, after that you can remove the smoke screw (the one with the anti tamper cover on the back of the pump) & turn it 1/4 of a turn clockwise NO MORE this will increase the over all fueling of the pump, if you screw the smoke screw in to far it will knacker the stop solenoid & choke the pump with rubber
