I turned up the boost a little, now I've got 9.5 psi. Guess what? It runs better now! Dark and stormy here, so I can't report on the smoke or lack thereof.
What a royal pain to adjust the waste-gate (Garrett) on these cars! I turned the rod 1.5 turns tighter, which I had understood should have bumped the boost by 4.5 psi (3 psi per turn). No more time to play with it tonight, later I'll try tightening up another turn. I'd much rather get all the other adjustable things and correctable things taken care of before I swap injection pumps. I'd like to get the boost above 12 psi, and back off the ALDA a bit, and install the correct glow plugs. If the car still runs unacceptably, I'll consider swapping in the correct IP. ------------- Max Charleston SC On Sat, Jan 21, 2017 at 6:04 PM, Karl Wittnebel via Mercedes < [email protected]> wrote: > I agree that putting the wrong pump on the car is asking for problems and > might explain everything.
