I made the modifications in your post to my ignition except for the extra resistors between the ignition and TPS-sensor, I didn't add them.
After some experimenting with what values I wanted to use for my curve, it now works and adds 10 degrees of advance at low throttle-usage.

thank you for the feedback
I must admit I don't drive my blue elan enough and have not (yet?) taken the time to fully optimize the fuel economy aspect via the TPS sensor... I hope you'll be succesfull and will get a long and happy motoring with the Z
keep it on the road...

If they could do this and the system dynamically taught itself the best data points to avoid knock there would be little need to do much in terms of initial calibration. Next generation perhaps.
