Injecor impedance?

[:) :(]

One more question: Do you know how those litte black bosch ignition modules 
(The small ones with a big heatsink and 5 or 7 (Can't remember.) pins 
(Power, gnd, hall sensor and ignition coil) work? Do they have some way to 
control the dwell or are they only "dumb". I plan to use a couple of them in 
a distributor less ignition if I can get the fuel controller to work.. Would 
be a bit easier as i have a few of them laying around.

A couple of more things:Is it a lot of oscillating going on in the pressure 
sensor signal? Plan to sample once per revolution and i do not want a lot of 
difference between the different revs. How many loadsites do you´need to 
regulate the fuel decently (was thinking of 8 rpm and 8 map total of 64 
sites), of course many are better but what can be sufficient, as I dont want 
the mapping to take all day.
