While in DC I rode in MattDavid's car. It does indeed run (which is more than you can say about certain other DeLoreans...).
What potential EFI'ers need to keep in mind is that MattDavid spent years getting his car to this point. It certainly was not a plug & play installation. Each car needs to be individually tuned -- not a short term process. As MattDavid's car proves it can be done (quite nicely), but anyone considering the same needs to understand what the entire project will entail. Fitting components onto the engine is just the beginning.
This is where I disagree with Owen Malbec.
