Thanks so much for the pics of the switches.
And it is way above and beyond making a diagram. Wow.

Even if someone go previously rid of their port, theoretically they could make their own "port" if they got creative with wiring.

I'm sure a male plug could be 3d printed. And I'm sure someone could figure out how to send all that data to be displayed on an LCD screen either in the car or on an external consol. Use one of the empty pin positions for oil pressure and temp sensors, CHT, etc...

Too bad my 71 came without a plug from the factory. I was planning to get the similar BMW console (see my post from many years ago) for my 2002Tii, but we decided to move and I had to sell that car.

My 1971 Super Convertible (built March 1971), and owned by me since 1976 (second owner) has no diagnostic block but does have a flat area for one apparently for future models.

On the picture above showing the switches. To measure VR volts does the 15 terminal on this diagram on the left side need to be switched on too together with the Generator switch 14 ?

Several years in the making, I have completed a reproduction of the diagnostic test port made by VW. It has a lot of the original functionality, but not all (namely, its missing compression testing). Fully my own design including 3D files, electronics, and code.

I believe this is the only one in the world capable of testing the lights and RPM.

Very cool, Jordan! Remind me not to butcher the diagnostic plug on my next Super project!!!

Do you plan on making more of these to sell? Is it able to read what timing is set to?

Amazing, Jordan!

You might want to check into producing.

VERY impressive !

I am officially humbled, wouldn't even know where to begin. lol

I love how your RPMs started around 1400 & settled to about 850 +/-. Showing fast idle cam & choke are set right & not having to fiddle with gas pedal, as it should be.
Well done.

Many would buy if available ... stay safe

Thank you all.

It isn't capable of determining timing, my vehicle does not have a TDC sensor or spark plug wire sensors, so I couldn't build that functionality. I get the tach signal off the coil -.

I am considering producing them, but I'm not sure the price point would be attractive. There's at least $50-80 of materials in it, and it also took several hours to splice all the wires together. The price point would probably have to be well over $100.

Perhaps a version that only does the tach and starting/stopping the engine would be cheaper and more feasible. Ill give it some thought.

Jordan, you'd have to charge a minimum of $250 USD to make it worth your while. Your labor needs to be factored in And that's if you can get the materials at a lesser, wholesale, cost. If you could figure a way for it to also time the engine, which would make it pretty much all-in-one, another $50 would not be asking too much, compared to all the separate devices you'd need to accomplish the same thing.
