driving two coils on ms1 v2.2
 

Has anyone done mods needed to drive two stock miata coils on the ms1 v2.2 board? I appericate the information
THanks

is it possibile to just drive the igintor instead to fire the coil packs?
Thanks

Gonna search around the ms extra manual

you do it like any other v3.0 install....um i have the diagram somewhere... let me look for it.

I appericate the help

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

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.

post pics, they might have modded the board?

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.

beyond me...

haha well if you have some pictures of the mods on a real board I would appericate it to see it. I could go from there.

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

schematics in link should help

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

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.

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

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.
