As some of you know, I've been suspecting my vp44 was on its way out for a while now.

It's official, as soon as I can get the funds up, Blue Chip Diesel will have an order!

My vp44 is due to computer failure. Intermittent dead pedal, that has continued to be more and more common. At times it would be at initial start up and go, and others it was at highway speeds (rpm around 1200). I wouldn't lose throttle completely I would get about 100 rpm fluctuation as I feathered the throttle. At times, if I floored it, it would suddenly come back, but this had to be tearing up my drivetrain. If I got off the pedal for about 3 seconds and then back on it, it would come back, for a while.

In the meantime I am going to have to limp the truck around, through the work weeks.

I know Chip has stated on his site that for one reason or another, a computer relocation wasn't viable. I am hoping some of us can shed some more light, and input into why we cannot get the vp44 computer away from the heat of the engine, and hopefully add to its life.

Although it wouldn't be the most helpful, could I fab a finned aluminum cover that could act as a heat sink? I recognize this may not really be much of a solution, because the heat would still need to travel through the circuit board (and soldered connections) to get to the heat sink, but it seems a shame that I will be putting $2,000 right back into the "belly of the beast" without providing it with any additional protection from what I know is causing the damage.

 

Update: Blue Chip premium upgraded rebuilt pump installed!

Nothing but praise about Blue Chip! Pump was shipped super fast, their tips list helped huge, and the nice quality finish on the pump gives a clean look to the engine compartment.

It's so great now to be able to pull out to pass and not have to wonder if I will have the go pedal or not, or come up a grade, and not lose the throttle have way up.
