[DeTomaso] mass-flo injection

[Göran Malmberg]

Someone raised the possibility of the Mass-flo injection for the cleveland.  
The system looks really great to me, but I am really concerned about 2 
things:

1.  Their web site indicates that it makes no difference if you use a single 
plane or dual manifold for thier system. In brief, this suggests lack of 
understanding of the importance of runner length in injection.

2.  Their system uses a standard for mustang computer.  I don't understand 
electronics completely, but I am concerned that a standard fuel-timing map 
for a mustang 5.0 would not be ideal for another engine.  maybe I am wrong 
on this one, but then why do all other EFI systems have you build the fuel 
and timing maps?  Justin

If we look at their website we can see that they use a in serie hosed fuel rail. 
In my previous inlay I stated that this is the wrong way of doing it. A high Hp 
engine may lean out the last cylinder.

I also explaine a little about that there is a difference between a port injection 
system and a carb engineered manifold. I guess what they are saying is,
the plenum design, dual or single,  is not very important in port injection system.
However, the RUNNER is important since this is a tuning situation. A dual plane 
usually has smaller and longer runners, which sets the rpm band lower.

The whole trick with a fuel injection is that it is possible to tune for the specific
engine in question. But there is a market for all kind of buyers.......
Of course, you must build your OWN map.
