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

 

Blown fuse, if hes lucky.

 

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.
