Cant get car to idle right after gov. mod.

[macsdub]

then use the governor spring setup from a industrial style pump,like the 4b pump i have
the governor is just 1 spring+and its a different setup
we just need to find a spring that allows higher revs than a cummins spring would allow

that governor setup in our vw's is an "oddball"

 I don't think QuickTD is necessarily implying that he raised the speed of the engine, just that he increased the fueling relative to engine speed instead of reducing it like a typical governor does.

 Exactly. Using a single extension with lots of coils (industrial governor) and the proper initial tension can reduce the governor "droop" enough to make the car undrivable, if thats what you want.    The VW setup is designed to produce a fairly user friendly power curve.

BTW. I managed to get the idle better. Better than it ever was before in fact. I backed off the residual fuel pressure more and then adjusted the idle with the see-saw thing. It's rock stable, and even if I use the P/S, A/C, or both at the same time, it dosen't move at all. It also runs with less vibration than it did before at the same RPM. Wonder what that's about.

hi guys

u really don't want to use the cummins governor setup.

it is called a Variable speed governor. this means that it governs
the speed of the engine at any given throttle angle (your pedal)
for any given speed. Any change in load will then in turn reduce
the rpm and it will try to increase it all by itself without any further
input from your pedal.

the traditional governor for automotive use it call a min/max gov
it only governs the speed at full rpm to prevent overspeeding and at
idle to give it stable idle.

people prefer to govern the car speed (rpm) with their foot on the pedal
otherwise it seems to take away the control of the car.

BTW you won't find a cumins spring that is capable of going 5000-6000

hope this helps.
