    I have posted a thread on fitting a compufire ignition to my bay in the handy hints section as the kit is not type 4 specific and could be fitted to an upright motor in a bay or splitty as well. Here is the link

    Well done Alex - very informative.
    I'm running the Compufire Pointless Ignition a much easier install and very happy with it.

    I just had an electronic ignition fitted to shirl, am very happy with it, no flat spots, starts first time. Cost me around $180

    This is what I had fitted

    Ian,

    Do you have the 009 or the 005 dizzy?

    Well I did my first good run with the electronic ignition to the Newcastle and back - did 410km before filling up and put in 39 liters - which works out at 9.5 litres per 100km.

    At this rate the electronic ignition kit will be paying for its self and saving me $$$ in a few months.

    Well below average by my calculation. Wow. Can EI really make such a difference? The air loves you for it, Ian.

    I'm quietly hoping it really is the EI making that difference, because I am now the proud owner of one, exactly the same. It's not fitted to anything yet, but soon will be.

    Thats the same unit I used to have in my 77 years ago and it worked a treat, although I do remember having some trouble with it at some point but it is a while ago.....

    1968~79 VW Type 2 ignition system upgrade

    1968~79 VW TYPE 2 IGNITION SYSTEM UPGRADE

    Compiled & Written by Nigel A. Skeet


    The Author's 1973 VW "1600" Type 2

    During the mid-to-late-1980s, we found increasing difficulty, with firing up the engine of our 1973 VW 1600 Type 2, following a dewy night when camping, or after a winter lay-up period; often requiring several bouts of turning the engine over on the starter, spaced over a period of about half an hour or more. When tested, the H.T. ignition circuit produced an adequate spark, but never particularly strong. The standard H.T. leads' connections to the spark plugs, being exposed to the atmosphere, rendered them susceptible to condensation, resulting in leakage to earth, which I suspect may have been the major factor. It is also probable that the ignition coil had slowly deteriorated over the years and so was not performing as well as it should.

    Thus, in early-1989, it seemed an appropriate excuse to upgrade the ignition system, which had the desired effect; resulting in on-the-button starting, under all conditions. This involved the fitment of Lemark 'Hotwires' HT leads (having rubber boots which seal over the spark plug ceramic insulator), a Microdynamics Formula 1, FCD (frequency controlled dwell), exponential discharge, electronic ignition, together with a Microdynamics Macrospark, low inductance, ballasted ignition coil.

    This electronic ignition system, also incorporated an adjustable, electronic, smooth-cut rev limiter, which was pre-set for us, to 5000 RPM (the absolute maximum for the air-cooled VW 1600 engine, without a special counterweighted crankshaft and fine tolerance balancing!). It enabled us to dispense with the cut-out type rotor arm, which had resulted in extremely violent juddering of the whole vehicle, when 4500 RPM (corresponding to a speedometer reading of approximately 50 MPH, in 3rd gear) was reached.

    The higher rev limit, allowed us to attain higher speeds in 3rd gear (circa 55 MPH, corresponding to about 3250 RPM in 4th gear), so that we might have barely adequate torque & power, when we changed up to 4th gear, which was often found to be necessary when joining a motorway, on an uphill slip road and other driving conditions. A close-ratio, 5-speed gearbox, would have gone a long way to overcoming this problem, but that's another story!

    Over the years, accessory electronic ignition systems, which use either optical or Hall-effect triggering, have become popular, because they dispense with the need to adjust contact breaker points. However, these systems are said to suffer from timing errors, owing to backlash and mechanical hysteresis effects, associated with the ignition distributor, dog and skew gear drive mechanism, which is no longer biased and damped, by pressure from the contact breaker spring. In the event of these types of electronic ignition system failing, there is seldom a simple way of reverting to the simple, standard ignition system, owing to the distributor modifications which are made, to incorporate the triggering device.

    Unless you use a pertronix which doesn't require distributor modifications. Mine arrived friday and i'm yet to drop it in however.

    I am dubious of the date of the extract though, a lot changes in 12 years.

    Hopefully it goes good :)

    I just installed a Compufire kit in a new 005 SVDA, the full rundown is in another thread but in a nutshell the only modification necessary was to the cell to make it fit inside the dizzy. Other than that, working fine. In the same thread the Pertronix kit gets a thumbs up from Tom (ttmck) which would be a considered endorsement I'd say!

    With a 009 there is no modification needed in a Type2 1700/1800/2000 with a Compufire install - well at least the one I got in.

    Just fitted the pertronix to my 77 efi 2 litre kombi. Actually one of my best mates who is an auto electrician did it. Unbelievably smooth. Cant wait to do a highway run and check the mileage. Wish I had listened to my mate who said to get one 5 years ago

    Installed the $45 electronic points as advertised in VWMA. Not rocket science to install and going well after 2500 km Easter trip. Recommended.
