All the extra stuff is why I believe it would just be easier to have new injector lines made and correlate them to the correct cylinder. This would seem to be much easier IMO.

I misspoke when I was talking about how the jack shaft would affect the IP. The problem I would still run into would be it trying to operate in a direction it was not intended to run. It would still probably have issues with the optic sensor and stepper motor I would assume.

The Ford Db2 pumps do push more from what I understand but the Ds4 has a four plunger pump head and I was thinking with sobe modification might be able to push near what a Db4 pump can push. Plus you have more accurate timing with Ds4.

I believe its the cam ring that makes the IP spin how it does. Not the direction the engine spins. I understand jack shafts but I'm not sure if I understood your post correctly.

So I was thinking, correct me if I'm wrong, but it is the cam ring that causes the pump to spin the direction it does? So I was thinking, if that is the case, that I could match the Ford firing order by getting custom injector lines and matching them up the where they need to be on the Ds4...

Bump. Any updates?

Does anyone have any idea what burns out on the PMD? Is it commonly a certain component on it? If anyone has a bad PMD, I could throw it on my test bench at work and see what fails on it...

It might be a pipe dream to do this. If the Ds4 was engineered properly in the first place, it could have been similar to what a Vp44 pump is on a Cummins. Like Thefermanator mentioned in his posts, there might be a way to simplify it and thus make it more reliable. And with a PMD, there is...

I will look into an arduino board as well. I'll see if I can find that thread. I do think I want to keep it simple, so that might be the answer there. As far as the optic sensor goes, if it doesn't work, there is always the possibility of finding a replacement that will. The easiest thing...

Thank you for the helpful post. Yes pm his name when you get a chance. As for the sensors, I was thinking of starting with trying to adapt the stock 6.5 sensors. I'm not sure how easy it will be to adapt them until I try it. And I didn't even think about the optic sensor possibly needing...

Anyway another question I just thought of is, if I change the direction the pump spins, would the program have to totally be rewritten too? I mean just to make sure the injection events are happening in the correct cylinder? I hope that makes sense. Lol

I am fully aware of the mechanical versus electronics debate. I work with electronics and do circuit card repair as well so that really isn't my main concern. I just more want something to tinker with on a vehicle that is not my daily driver... As for the Moose Pump, already have one. I've...

There would be a lot of complications for sure. I'm not sure it'll even work to be honest. I'm just kicking the idea around at this point and doing research. I believe you are correct about the physical size difference. I didn't even think about that to be honest. I'll need to figure it out...

Also I forgot to ask, has anyone developed any mods for the pump that is public knowledge? I know Heath Diesel has the Merlin Pump but I haven't read what exactly they do to get the extra fuel. I do wonder if the cam ring from a Db2 can be swapped? I have seen that suggested before and that...

I know the Chevy pumps spin the opposite way from Ford pumps, but is it possible to make the DS4 spin the opposite way? Also from what I have read is the crank sensor used is pretty specific to the 6.5, is there a way to adapt it to the Ford IDI crank? I haven't really seen what the cover the...

If a VGT is not controlled properly, it will tend to have higher than normal back pressure due to not keeping up with the flow of the engine. By design, a VGT will have slightly higher back pressure, especially lower in the rpm band, which is why it spools so fast but having something that...

Thanks for the info. I will get ahold of him. I am extremely curious about all the info he would share.

What are the inherent issues you mentioned about the Ds4 other than the PMD? Also what is the max fuel that can be had from those? I keep hearing different stories about the max fuel. And Heath Diesel got 500hp from a supposedly stock pump. I'm not so sure about that though. There has to be some...

I have thought about this type of injector before as well on a Ford IDI. Do you think those internal springs from the AAZ injector could be used on the the 6.2/6.5 and Ford 6.9/7.3? That could be a possibility instead of swapping over the whole injector. Also do you think there can be any power...

Any guess why it happened so quick? Also what were you running for an IP?
