Can someone verify Correct spark output?
I have to constantly be messing with something electronic, this damn megasquirt project got me stuck on it. That said I decided to pull the case back off my megasquirt and verify that I wired everything up correctly for the two inputs from CAS and two spark outputs. From the beginning I believe I used DIYautotunes mods, but I did the mod a long time ago before v3.0 was released if I remember correctly.
Anyway I'm planning on using the stock 1995 Miata coil packs. So what I did was removed the transistor from Q9 and Q11, from the ouput side of R25 I soldered on a wire and ran it to X13 for coil number one. Output side of R28 to X12 for coil number two.
Thats all I remember it telling me I needed to do, but now I look at their site and the redirect to a Neon site tells me I need to use some transistors or something? Ack! I'm confused, just want to make sure this is all right before I Blow something up. Now I'm really getting paranoid. The input section is perfect, I've checked that like 11tybillion times now.

spark output must be inverted if running without the resistors, else you'll burn out the ignitors.
It also proved to be a more unstable signal, imho, i never had a smooth idle, and always had misses. Reverting to DIY's method, using the transitors and taking the signal off the LEDs, my idle became much smoother and misfires are a thing of the past. Spark output signal must be reverted to non-inverted

yes. you can buy the transistors and 1k resistors at radioshack for about $4.
install the transistors, then jump, IIRC (dont hold me to it), r23 (closest to transitor) to the - labeled side of the LED, and r27 the same.
run the outputs from the same resistor/LED spot to your x13 and x12.
like this:
remember, non-inverted spark output.
