Thx for the msq, Pat.
Jared, they definitely need to go to JS10 instead of going to JS8. I made the same mistake. However, I'm pretty sure they are not needed with the 'new' input circuits (be it Abe's, Jason's or drytoast's).
I completely removed the 1K and 470R resistors and capacitor to JS8/JS10.
Instead I built Abe's circuit on the VR area of the board (see my reply in Abe's 40% thread, here's the circuit
). It's ABe's circuit, but I reordered the components so they fit in the VR area. .
I did do the ignition output mods of course (the 2 x 330R to IGN and IAC2B)
Since my failure of getting RPM readings in step 55 of the build, I haven't done further testing with the megasquirt. I'll try again when the MS is completely finished. Waiting on a couple of NPO capacitors for the input circuits :(.
I left out R37 and R38 because I broke one of the pins while bending it. Might try to install them again if the area is not being taken up by other mods. No longer have the double sided tape though. Don't know if it's ok to install them without contacting the heatsink.
Don't forget to put a dab of silicone on the crystal.
Did you install the flyback diode for the TIP120? I don't see it in your pic.
Want to do constant VICS, fans, barometric correctoin, launch control, waterinjection and knock detection. Haven't checked yet if there's enough outputs even to do all this. First 3 are necessary, the other ones would be nice to have.
I haven't decided on boost control. Probably never going to use it, unless it helps spoolup maybe.
Haven't looked into software settings at all. First want to get a grasp on the hardware, software comes later
