Electronic ignition
After spending a number of hours at Paul Goys Racing today trying to get my car running well I've decided the winter project is going to be
convert from points, etc to pointless electronic ignition.
To open a can of worms, what is available and at roughly what costs. The engine is a 1600 x-flow running carbs.
Just an aside the guy was really helpfull and when he got it runing properly it was developing about 110bhp, without being absolutaley flat out on
their rolling road. To hear running at 90+ mph on it was something else. If you are near Lincoln I would recommend them

I think you can use a valencia dissy with some sort of module, someone else was doing the same, can't remember his name though sorry  might
have been marcus ??

Cheapest way is an Aldon Ignitor. This is a small amp and a hall effect magnetic pick up. It all fits in the existing distributor and uses the
existing coil.
Next cheapest is Luminition again retro fit to existing dizzy for the optical timing bit and a smll box amplifier that bolts onto the bodywork, again
good and not so expensive.
These both have a timing curve generated by the mechanical and vac advance in the original dizzy, not mapable as such but can be tweaked by changing
springs etc.
Megajolt and Emerald are much more like "modern" electronic ignition, can be hooked up to a laptop and you can mess with the advance
curves as much as you want, come to think about it 1920s cars had an advance /retard lever on the steering column so you could adjust as you drove
along try doing that with a laptop!

The Valencia/Bosch distributor from late 80's Fiesta etc is a relatively straightforward replacement.
As well as the dizzie, you'll also need a non-ballast resistor coil, and a side exit cap from a Fiat Strada (available off the shelf in
Halfords),
You'll need to modify the loom to remove or bypass the ballast resistor wire.
Cost is minimal if you can find the dizzie as they seem to be getting a bit scarce now.
Megajolt would appear to be the better long term option. Quite a bit more expensive though and more work involved.

Whats involved with this megajolt I keep hearing about, rough cost and whats involved with fitting it. I've got no problem with electics, so I
shouldn't have any problem in fitting it. Do I retain the dizzy or does it use some other sort of sensor?

MegaJolt uses a toothed wheel sensor , the toothed wheel is usually mounted onto the crank pulley.
