I haven't even gotten my MS2 working yet, need to work on that. The pulses coming from my CAS seem impossibly small, too small to trip the opto-isolator. Gotta get that one sorted out so I can see RPM, get the sucker working. Then it's tuning and A/C time.

Thanks for all the info!

If it makes you feel better, everything was simple except my coil-on-plug... which I'm still convinced the coils are bad. lol. Good luck, Sir!

I'd love to see what happens when you ground 1B :rofl:

Blown fuse, if hes lucky. :eek5:

My car's now running from my megasquirt - in a standalone config. It was interesting doing the troubleshooting, but after adding more wires to the MX-5->MegaSquirt adaptor, I was in business.

I've still got to hook up the idle control motor, tach, aircon, and thermofan. Then the fun mods will come - launch control and boost control.

It's taken a lot of research and pouring over wiring diagrams, but I'm getting there.

I'm running a custom-built MS (originally from DIYAT), Innovate LC-1, 330cc injectors, standard 1.8L ignition system, GReddy turbo (only the turbo - the rest is custom) and a rebuilt BP engine.
