I have the Shoebox ECU monitor. I got it without the ECU and did my own
soldering and wiring. Unless you are good with fine work and soldering,
don't.
To get best use of the thing, knowing how to interpret the thing is half
the battle. Big advantage is you can have it back by the engine while you
work and also up front while you test drive.
The first time it helped me isolate a bad coil. Had no coil signal.
Replaced coil and it fired right up. DSecond time it was a bad ECU. I don't
remember exactly the interpretation. But once I decided that was the
problem and swapped out, all was well. I just finished reworking the
throttle switch. It was so easy to adjust with the ECU monitor. One time
the hall sender didn.t light up. Replaced it and all was well.
The system works pretty good. Saved me a lot of time and headache..
It's a worthwhile gadget in my opinion.

I had a quick look at the Shoe Box website and the PDF for this unit.
I didn't see installation instructions but looking at van-cafe and Shoe Box,
it appears that a known good ECU is supplied with the 'ready to go'
monitor.
I swear I recall that some folks might've soldered the Shoe Box
connector wires to
existing wires at ECU connector. But looking at this Digijet ECU image:

I can see how those pins would be more forgiving in terms of soldering
new wires on.
As to my earlier speculation on what the monitor does, from the PDF:
"Basics
It is important to keep in mind as you are using this System as a
troubleshooting tool, the monitor and ECU simply allow the user to
monitor input and output signals at the ECU......"
So it measures inputs AND outputs.
I'd suggest that for an experienced hard core enthusiast or mechanic,
this tool would be
a really useful time saver.
