Unless you get the advance specs from the distributor seller, you'll still be in the dark. The curve might be totally inappropriate for your car and cause big problems and not run right..
You can get your original one rebuilt at a specialist who can check and adjust the advance curves and put in one that suits todays fuels and the spec of your car.
phillb helped me with the blackbox kit for my car. You lockout the advance mechanism with tie wire, I added a new electronic points set and you wire the blackbox into the car (I think only 4 wires). I've now got my original 25D back in my car and unless you spot the extra wire to the coil/distributor you can't really tell it apart from stock. There are a couple of photos in my build thread on the last two pages
viewtopic.php?p=1013438#p1013438There is a thread on ausmini here. Unfortunately most of the photos are gone now
viewtopic.php?f=2&t=83483&hilit=blackbox Yes I understand, this is a seemingly very important aspect that sellers don't really seem to care to provide any information about.
I know what you mean. I bought a powerspark high energy dissy and they would not provide any specs. I mapped it myself and the graph below shows how far away it was from what I needed.
