Hi all...
Will a GM HEI 4-pin ignition module work with Speeduino? I see only 7 and 8 pin modules listed in the hardware requirement section.
I am attempting to do this upgrade swap... https://www.zdriver.com/forums/240z-280 ... hei-27569/
When I connect everything, and connect the signal wire to IGN1 output, the IGN1 led on the board (once flashing) goes solid red. I measure 8v as out of the module. And before connecting the signal wire, I get a frequency of 25 hz, and after it jumps to 120 hz. I'm currently running everything on the bench, and I did not have spark when I connect everything.
Anyone advise? Thanks in advance.
