Thanks for the reply’s, I went for the Aldon Amethyst in the end. Can someone who has this kit advise how the static timing is set ? The instructions suggest the below however what does it mean by specific timing with just the ignition turned on ? Like 9 degrees at TDC or lining up the crank notch with 0 degrees at TDC ?
Now turn on the ignition. The LED on the Amethyst unit should be on when the coil is on (i.e. with the points closed on a traditional system), and off when the coil is off. You should see the LED turn on and off as you turn the engine by hand.
Adjust the distributor so that the LED turns off just as the engine passes the vehicle manufacturer's specified timing point.
At this point, you can re-fit or tighten the spark plugs,
How did you get on with the Amethyst?
I am looking for an ignition setup for a 1310 engine I am building, I may start with the build remaining Naturally Aspirated, but with a view to converting to FI (Supercharger), at a later date when I get everything sorted out.
The engine is not yet fully built up so I am able to adjust a few things, but want to be able to add a Supercharger later without having to remove the engine.
One area that needs changing is the Ignition, so I have been advised to go with a mappable ignition that will suit the FI setup (but will work with the NA setup initially).
I thought about an Amethyst as it appeared to be good and cheaper than a Megajolt setup, however everyone is telling me that I should go with a trigger wheel from the get go?
