IDC sensing HSF-3

[kellygnsd]

Richard,

I have fairly large injectors, around 1200cc/min but as stated above I'm driving the HSF-3 controller via an aux output instead of from the actual fuel injector signal. Should I still solder a bridge on the 1.5x gain pad and break the 1.0x bridge or will the 1.0x gain be sufficient?

It seemed like when I tested the system I wasn't able to get below 4 bars on the flow sensor with injection triggering at about 7.5%. Is that about right with the .9 and .8 nozzle installed?
