The MegaSquirt is running 4 injectors,
4x35 PPH low Z injectors from a Turbo
T-bird, and the stock ECU is still running
the cold start and fuel requirments up to
around 2 PSI, after 2 PSI the MS adds the
additional fuel needed to keep from running
too lean.
I just re-flashed the computer with the dual
table program, this allows for 2 different maps
to be programed, the reason I went with the
DT programing was to get a true 0 pulse width
when there should be no fuel flowing to the
injectors. with the standard programing the
injectors get a 1.0 ms pulse, which is the open
closing time for the injectors.
I noticed at an idle the motor was running a little
rich, more now with the bigger injectors.
When I was runing the 19 PPH injectors it wasn't
a problem.
Other than the cost of a laptop that I had allready,
my total cost for the MegaSquirt is around $200,
and that would include the cost of the injectors too.
You can't touch a system like this for less than
$700-$1000 so this was really the only way to go.
Totally programable, super versital, and with the
dual table, I can drive the EFI and add a water
injection as well, all computer controlled, hows
that for cool
