I am new to this forum but...

The time taken for a coil to saturate with to a given voltage is a function
of the voltage and the amount of energy it can store. This is expressed in
"Henrys", or mH for 1/1000 of one...

(similar to thinking of how long it takes to fill a bucket.)

If you got right into it you'd probably have to factor in the supply voltage
resistance and copper losses (DC resistance of the coil metal).


Does anybody know if it is possible to use the "learning" Chev injection
system on a 6 cyl engine, and is this easily done? The EFI systems we have
here are not full time closed loop. I believe the Chev one is...
