You need a toothed wheel on your crank shaft and an appropriately mounted sensor. I have seen these advertised on Ebay for between ?10 and ?20. I have also seen complete EDIS Systems inc. the sensor for ?35, specifically aimed at people wanting to use MegaJolt/MegaSquirt.
you can either use a throttle position sensor (TPS) or a Manifold absolute Pressure (MAF) sensor for the MegaJolt ECU to determine how much the throttle is open. You can specify which type you want to go for when you order it, if you get it from Brent in the States…
The whole point of it is so that you can gain 100% control over your ignition advance curve as the engine progresses through the rev range, with any given "load".
When using a carburettored engine, this can ensure that you are gaining maximum power, with no flat spots, from go right up to the rev limiter. Normally, mechanical devices would have a compromise and have some flat spot somewhere throughout the range. EFI cars would have this sort of thing (along with the fuel injection control) diluted down a bit for economy, until you chip them.

All in you can do it for around ?200 I wreckon and it is the way I am going to go with my valver on carbs eventually!

Going to get it going with STD dizzy. Once happy the engine is OK, I'll spend the money on the MegaJolt.
