black smokin diesel,any change in your mileage? any more smoke?
so, after all that time as anyone tested this and measured the gains?worth to do?none/minimal risks?
Tapping the internal pressure adjustment pin into the body of the pump would be better if your pump is worn out. Or a better fix would be a new transfer rotor assembly.
Any more info on how to do this?
On some of our pumps we have the 12v solenoid that energizes @ a specified RPM or speed (anyone know what that is?) so if we were to energize it @ start up with key on power then do this mod would that be feasible?Here's why I ask. I did this mod when I rebuild my pump, not ever driving the car before gives me no reference point. I have a rpm range when the IP delivers less fuel (or advance) and once past that point it hauls ass.I dont have a tach so I cant give those #'s like I would like to do.It pulls hard up to 20 psi then stays right there as the RPM's increase until what ever RPM it is when it takes off again and pulls up to 35 psi no problem. I let off as it reaches 30 psi new engine and all.So I guess what I reachin for here is it feels like it advances up to a point then hold and advances more after a certain RPM is reached. I do not have my solenoid energized with keyed power and want to but I wanted to get some education before I did to see if I was heading down the correct path..?
See the 3rd post down. http://vwdiesel.net/phpBB/viewtopic.php?t=12856
So if energized at start up the advance will operate as it would in a pump without the ALFB, or the "load sensitive start of delivery with deactivation feature". maybe?
