use 100ohm instead of 300ohm. That's going back to pin 11 through that 1K resistor. Normal = non-inverted

Techsalvager

huh is the red setup for the cas pickup? the one with a 1k resistor on it, the part where it goes between d9 and r13 where is the trace from or going to, if you don't mind that is, my board doesn't seem to have a hole there like that. But there is a hole in the board further to the db37 but in the same middle area.

Damn I need better info but I appericate it atleast its a working area to go from.

red is tach input, blue is spark out.

Apologies of the bad blurriness of them. Anyways I used pin two off the cpu to connect the .1uf cap to. but I'm not sure my 5v pull up for the cmp signal is correct.

Techsalvager

i do not iirc. id have to look on my desktop pc.

schematics in link should help

Techsalvager

yeah I see now better where the two wires for the igintor is going.

Techsalvager

ok I did the coil mod I just had to wired it from the LEDS to the db37 directly since I don't have a pin hole that connects at those sports, should still work fine.

Wow...

I haven't seen a rev 1 board in... ever.

That is all. I have nothing useful to contribute.

Techsalvager

no worries already got it figured out after looking though all information around.

Techsalvager

the info, pics you gave me is that for driving the iginitor or coils directly?

ignitor.

V1.01s are pretty much V2.2s without the breakout jumpers to make adding extra circuits easier.
