Anyone have any opinions on it?

Do lots of searching on both Megasquirt and D-jet. The MS forum is a good place to start. This a quote from one of the posts:
Using the D-Jet system will require you either fabricate a TPS (the stock D-Jet unit is just a switch), or you use the MAPdot option (search here for more info on this) and don't use a TPS at all. The other D-Jet sensors can be matched to the MS, except the MPS, which you'll replace with the MAP sensor in the MS (this is good, as the D-Jet MPS is impossible to rebuild properly, and finding working one is difficult). If you get a really complete system, it will even have a fuel pump and an adjustable fuel pressure regulator, though these parts can be sourced separately fairly easily. The D-Jet injectors are low-impedence (search here if you don't know what that means).
I've been doing some investigating but I have not started any work yet. Also since the K-jet is a mechanical system it is not as easy to adapt to MS.
