electronic ignition

i did a quite detailed post about this on poloclub forum but unfortunately the site got hacked and everything older than this year was completely deleted. real pain.

the distributor came from a saab 900 2.0 16v. think it was about a E or F plate. it differed in that it had 3 "loops" around its edge, you know the bits that the bolts go through to fix the dizzy to the engine. so i had to chop one off, and manipulate the other 2 so i could twist the dizzy body to get the correct idle timing. this also meant that the vacuum bulb wanted to be right where the thermostat housing / temp senders are. so i just removed the vacuum bulb. still has the mechanical rpm advnce inside the distributor. vacuum advance is really only for part throttle economy anyway, its not missed.

yep dizzy has a hall sensor, which triggers the ignition amplifier in the base of the coil, and then the coil itself. completely stand alone system. off the top of my head all it required was an earth, live and switched live. also, because of the cavalier parts i used i had to solder the saab hall sensor plug onto the cavalier wire. ive been told that the late mk2 and early mk3 (MH engine is it ?) polo ignition system will plug straight into the saab hall sensor socket though.

you might be better off with the mid to late 80's seat ibiza sxi (the one with the 1.2 porsche managed engine) distributor if you are going fuel injection, its much more compact because it doesnt have mechanical advance inside it, and will bolt straight onto the HK engine.

a few people have done a electronic ignition conversion, using differing methods. will usually get the info you need if you post in the mechanical section.
