With all the discussion about injector controllers, the group may be
interested in a new design controller a friend of mine who monitors
the list has designed:
All digital design, 8751 micro
Uses GM map sensor, adaptable to 2 or 3 bar
Peak and hold injector driver
Has trimpots for:
min psi of boost at which injection starts
min pulse width
gain, eg: the change in pw per psi of boost
Has dipswitch for min rpm of injection
Has synchronous injection per rev ( eg: every 2,3,4 ref pulses)
Setable for 4,6,8 cyl
LED bargraph of pulse width or duty cycle
Unit has application in factory turbo cars where you have either maxed
out the MAF sensor or exceeded the limit of the car/truck's MAP sensor.
Could also be used for very accurate and adjustable water/alcohol
injection.
The designer depending on interest could make complete units,
preprogrammed kits or parts. He would be interested in others doing
the PCB and he supplying the rest.
In reasonable quantity, the complete units may cost about $200, kits
etc would be less.
Reply with your interest in such a controller, interest in doing a pcb,
and whether most would want a kit or completed units.
I am not the designer but will try and answer as many questions as I can.
