So I bought an AEM EMS4 for a 90 miata motor. My questions pretty much all pertain to the ignition system/CAS.

I am running Toyota Cops on the motor and I am going to run them sequentially and sequential injection as well.

I was only planning on running the stock CAS not a crank trigger, will that be enough to run everything sequentially?

Do I need the 4 channel ignition module? It says the EMS outputs "falling edge" ignition firing and I want to know if that is compatible with the Toyota COPS.

Is there anything else I need to know or should be aware of when wiring/setting this up? I've been having ignition problems with my MS1 and I made the switch to hopefully alleviate those problems as well as adding better resolution and sequential ignition/fueling.

I've already looked around at other threads but saw no mention of these specific items up for question, which is why I posted looking for some help.

Thanks for the help guys

 

Toyota Coils are Smart coils. No igniter is needed. I have done your combination before. The only difference is I put a Higher resolution trigger disc in the early CAS and, I had a MSM engine.
