On the subject of scopes I have a box of parts on my desk that will allow a sound card on a old laptop be a low frequency oscilloscope.
Results soon. It's simple.

TCI Replacement 2020 It Works
- Thread starter Team Junk
- Start date
Just found a few Youtube videos showing how to make your smartphone into a scope. Got an old Droid Ultra I just ordered the stuff for it.
I think holes drilled and tapped in the same spot as the TCI pickup. aluminum strip that is slotted for the stock TCI screws with the pickup attached to the strip.
..... or maybe convert my old Nexus7 tablet to a scope. I don't use it for anything else anyway...
This is what is recommended to me after your video.
The new Gonzo Logo ?
Proposed Gonzo intro page
Last line should read 70-79 points bike. 80 was a TCI iggy.
I'm in the midst of troubleshooting/repairing an issue with my '75, but I just had to wire up the Gonzo box to try it out before returning to the '75 work.
The space under the seat of my '83 was quite a tight fit for the GN, so I temporarily put it in the toolbox with rubber around it.
The bike started up easily with the GN, idled smoothly, all per usual.
I took it out for a short ride (more later today) and I had trouble recognizing any difference with the OEM TCI , but It did seem a bit peppier. Smooth acceleration.
This is with the untweaked OEM TCI; the engine was warmed up.
This was the first start-up with the GN box.
The engine was warm.

The white mark on the rotor is just slightly off-center (to the right of) of the timing mark, as you can see. I'll fix that 
After many searches I have located a GN250 User Manual. Here is the timing specification:
The Gonzo must be giving 25 Degrees worth of full advance if the maximum occurs at 3000 rpm - Perhaps it is actually a bit higher.
Thoughts.

Yamadude, well done! You have just done a plug n play trial and it all worked without any messing about. Excellent proof of concept

I have this in English. This info is for a last century GN250 and I think it is a different box.
Yamadude's trial indicates the Gonzo is matching the XS TDI very closely, if not the same, so there must be plenty of advance degrees available.
Signing off for the night now - All shops can open tomorrow in Wales. Back to work Wednesday.

Just put 30 miles on it, 40 - 60 mph.
My impressions remain the same.
Smooth, strong acceleration, no hiccups.
I was out on a country back road, coming up to a pretty lady walking along the shoulder,
and she put her thumb out to catch a ride! (no extra helmet on me).
But I think we can say that the Gonzo attracts girls!

Outstanding Dude. Here are some stills. Great comparison of stock vs Gonzo
It seems to advance at a slower rate than the stock TCI. Or is it just me.
