I know this is a very old thread, but I am working on almost exactly the same ECU and I hope you may still remember something about it.
I have a 1997 Suzuki Samurai 1.3 SPI/TBI with ECU **33920-80CG0 / Mitsubishi E2T47871E**.
In this thread you mentioned that your binary came from a 1998 SJ80 1.3L TBI and that you were going to look more thoroughly for the diagnostic link connector.
Did you ever find the **SDL (Suzuki Data Link) diagnostic connection**?
In particular, do you remember:
* which **ECU pin** carries SDL;
* which pin on the diagnostic/monitor connector it reaches;
* the wire colour, if known;
* or any pinout/photo/notes you may still have?
We are currently tracing the ECU PCB trying to identify the SDL pin, so even a small detail would be extremely useful.
Hello, I think the binary was from my samurais ECU. That samurai is -98 SJ80 (1,3L tbi). I didn't find the diagnostic link connector yet, but I will continue check more thoroughly at weekend
I was sent a copy of the EF01 binary today. I can now confirm that this ECU has an SDL diagnostic link, the code is very similar to the 8V Vitara of the same age but without an immobiliser, I was able to run the code on a 70E10 Vitara ECU I'm working on a TunerPro definition.

USA Zuks turn the check light on when the car is due for a service. They speak of a toggle switch under the steering wheel that you toggle to turn the light off for another several 1000 Km.
I sierra does not have an ecu or CEL/MIL ( yet so i can't help much more.
so i can't help much more.
