I was working on a 2002 6bt today with a VE style pump that is electronic controlled. It has the larger injectors like the 2 Gen trucks. Thought you VE guys might want to look into it.

 

That's a VP44. Similar in the way of a rotary/distributor style pump. Pretty much, as you said, an electronically controlled VE. With the reputation those ones have, I'm sure no one wants to bother making one work on our 1st gens. That's what p-pumps are for .

 

Has anyone thought to make a VW TDI computer work with a TDI pump but swap the head out for a 6bt head?

Hmmmm...

 

hey-Hey!!!,
Can a VE be mounted in place of a VP? They look more than a little bit similar in terms of interface parts...hmmmm...VE'd 24V.

I'm sure it could be done easily but how would the ECM feel about it?

 

I was thinking this same thing when I saw what the pump on my tdi looked like. I would imagine it would take a lot of time and research and some serious funding to get it going but you would have the most well controlled ve ever put on a 6bt. You could create your own timing curve based on throttle position, rpm and load. Smoke control would be a matter of re-mapping the injection quantity. You would need to rig a mass air flow sensor and a few other sending unit inputs but I imagine a computer tuning company could get it to work with the correct type of sending units and tuning. Would be very cool to say the least. Glad I'm not the only crazy guy out there!

 

I did not look at all the sensors but I don't think it has many. Nothing in the exhaust. I think it has a flywheel sensor and intake pressure sensor. Dont see a TPS but it could be inside the pump. I have not seen the ECM yet but it is on a log loader/processor. I have to work on it some more this week so I may be able to see more sensors. I would imagine that the ECM only controls the throttle like a governor and aneroid. Wiring is simple. Someone must have replaced the injectors and did not tighten them. It popped number four out. They also neglected to install the injector line brackets on the back three sticks. Number five injector line broke a few days later. I am replacing all three lines and brackets. Had to do a temp weld on the line till I could get one.

 

THey actually did make a electronicly controlled VE, How do I know you ask? I got one sittin here tore apart, actually some parts made it into the VE I just put together.

 

I don't think my 1990 has an ECM. It does not yet have a 24V either...
cheers,

Way ahead of you.
You'd need the VE timing case, cover and gear.
The VP lines appear to be adaptable to an Intercooled VE pump.
Yes, the firing order between VE and VP IS the same.

I've looked into a VE-ed '98.5-'02 with a Commonrail head and everything I'm seeing says it's doable, but there's a couple things that need to be addressed, mainly that you'd need to use VP injectors and run VE pop pressures.
The VP injector is a splendid piece, the versatility of adjustable pop pressures, in a more centrally located point on the head.
Used upgrade versions of these injectors are relatively inexpensive.

A VE-ed 6.7 is even possible with some ingenuity on the timing case.
Now THERE would be an engine that is a torquey SOB below 2,000 RPMS!

I'm around all kinds of these engines in various pieces and it's hard NOT to look at things from the perspective of a "hotrodder".

VP'd engine, Gen 1 timing cover and IC'd VE IP and use the VP's lines to pop-pressure adusted VP injectors. Probably want to do injectors of comparable size to POD's( 4x14, yes? ) or perhaps in between POD's and non-IC gen 1...

I volunteer guinee pig status for the project.

I'd try stock re-set VP injectors first.
I suspect the stock VP injectors have a better spray pattern than the VE versions, due to the number of holes and their more central relation to the piston's bowl.
Obviously we wouldn't be using a VE injector.

Better fuel dispersal to the bowl usually helps overall torque and horsepower.

A bit more fuel won't hurt the situation, either.
