What I see missing on a quick glance is a way for the AEM to get RPM data.

this sort of thing:https://www.innovatemotorsports.com/products/ssi_4plus.php

 

It looks like it's supposed to get revs off the CAN bus, and... well...

 

But I don't know if the 123 can output revs as an analog or serial signal.

but maybe I missed it.

Hopefully the MSD Tach adapter is going to get me the RPM's. It seem to be an inductive unit that clamps over one of the coil primary(?) wires to get an RPM signal. It is mentioned specifically in the AEM literature.

Ok, if they know it works, cool. 

 

The pickup looks to be just a current- to- voltage transformer

with a really cool name.

 

That means the AEM has at least one frequency input.
