nice thought about that for the N55, but decided to use the S55 dual pump. The N54 pumps are less expensive though. And you probably wouldnt need the Split second if they are mated to time the stokes to the N55 pump lobe. Which i also have 4 stroke pump lobe for the N55.
nice adapter for that though.
I also have Rail adapters and lines for that setup if you need them.
This is pretty cool for the N55 guys. S55 dual pump with an N54 attached to the end would work the same as the above, no extra difficulty as the MEVD DME can control the 2x S55 pumps, and an AIC would still just control the N54 pump.
I can control 2x N54 pump on the N54 DME, once I start digging into more MEVD code I may be able to get it to control an extra N54 style pump as well.
I have some concerns with doing this across the two different style pumps, as the N55 style relies on the vcv to the output of the cam position sensor. All MEVD should be able to control 2x of the N55 style pump with some minor changes. I'm also unsure how I feel about have both run constantly.
I would need to experiment some and see how rail pressure looks with an N55 style pump perhaps running on an N54, without the feedback of the cam position sensor. Initial thought is it would be pretty choppy. N54 style pump does not need this sync due to it being a rotary style.
FYI, I'll try to find the post but there are a few guys running the F series style XDI pump on early E series N55s. The VCV harness with an adapter is connected to the F series style pump and is controlling flow well enough even without syncing the pulses.
