I must admit, all the positives you get from ms are appealing, its just the initial outlay that puts me off, If I can do something similar for myself.. why not! In regards to the misfire, it has been sorted! it was the alternator after all this time! felt good to be able to drive it without the nast...

Last night I had a chance to have a quick fiddle and managed to drive the coil without blowing the fets, also had a look at working out how to manage advance. Due the complicated nature of the mechanical advance starting at around 1000-1500rpm and ending around 3000-4000rpm it will be rather difficu...

Also as mike said, a magnet adds signal strength and you basically have on you bike what I'm doing. But this will be a little more in depth.

Hi guys, as its not a digital system I cannot do the usual 36-1 but I can do 8 or a multiple trigger wheel and have a separate reset trigger like mike said. Since you guys said about the disadvantages with using the dizy I've reconsidered the idea and now going to use a crank trigger wheel. I've als...

I'm also making that from scratch, much cheaper ;)

Thing is, all you'd really be doing would be to get rid of the rotor arm and cap. I agree with what has been said with regards to the pit falls of a dizzy system, having said that I still run one with my programmable MSD 6530 unit, my dizzy is locked out and the timing curve is programed in to the ...

Thing is, all you'd really be doing would be to get rid of the rotor arm and cap. The ability to create your own map (easily) to a far greater accuracy than springs and weights can achieve is very worthwhile. Especially with an accurate trigger from the crank. EDIS is a stand alone ignition system ...

Hi guys, thanks for the comments. Initial quick comment, You will need 4 separate timed pulses to drive the coils. Are you going to have 4 pick ups in the dizzy?? If so the 8 tooth wheel in the dizzy will not work. Yes and no, It doesn't make to much difference, if I have 4 pulse's, each one will wi...

Home made Megajolt type ignition.

Hi guys, new to the forum and thought I'd say hi and share my lil project I'm going to start. I've had a Discovery 1 for about 4 years now I believe, and 2 years of that was spent rebuilding it, which included the Rover 3.5 v8 on hotwire. Soon after owning it, she started to suffer a misfire around ...
