Autronic SM4 in my 87 TII
I just wanted to let everyone know that I got my TII up and running with my Autronic SM4 ECU with the Autronic 500R CDI and 4 Mercury Marine coils. It took a couple days of trouble shooting to find out that: a) I had wired up the coil packs back to front and upside down, and b) all the gas I thought I had in the tank had evaporated since I put gas in it last.
After the fuel and coils were sorted (i.e. wiring double checked, and fuel pressure verified), the car started right up and started idling. Now it's time to button up the wiring and tune it; so far so good. I'll post pictures after I take some.

The stock CAS is triggering things. Since I'm running a v1.05 firmware, I have the ECU configured as a 12 cylinder 2 stroke engine, with 4 ignition events and 4 injection events.
I'm using pre-mix in the fuel on an S4, so I haven't checked out controlling the S5s electronic pump. From what I understand, you could control it from the SM4 like any stepper motor.
