This is for a 94' running off the CAS. Running sequential fuel (stock injectors), wasted spark with stock coils.

I am unsure about injector phasing, ignition phasing, and wheel teeth. Can someone verify?

Thanks!

i'm only qualified to say anything when I'm working on my car and it's fresh in my head and I have my notebook open, otherwise I forget things fast, so that said...

I assume "coil xB" is the wasted spark version of "coil x"? If so, you only have tooth 0 & 1 accounted for. You need to have 2 & 3 in there, otherwise nothing will happen ignition wise on those 2 teeth. As you have it, both coils fire on teeth 0 & 1 at the same time, and 0 & 1 only, ut oh.

Your fuel teeth don't follow the ignition firing order of 1,3,4,2. As is, you are firing the injectors in this order: 1,3,2,4. The engine will run, but...

I think on my series 1, the fuel teeth should be 2 teeth off the ignition teeth (360crank degrees off).

The fuel inj phase was copied over from the series 1 base map for the 94-95 miata, I noticed it didn't follow firing order so maybe the settings don't translate to the newer ecu. So should both Inj and coil phase read the same then (1=1,2=4,3=2,4=3)?. Also what the heck sets injection timing?

I am used to motec/megasquirt/performance electronics, AEM seems to handle cam/crank triggering so different so I'm having a tough time.

Can anyone that's running an ems 4 with a stock engine take screenshots of their setup for me?

Got an awesome answer from AEM directly, so I should be good to go. Once I get the engine running in a week or two I'll make a nice base map and post it up here so others don't have to go through the whole process again
