Another picture showing blanking plate where distributor was, the small screw in the middle secures a 10mm thick disc on the back that stops the oil pump drive jumping out of engagement. The bit with the wires on rad top hose connection is a thermal switch that will be used to control an electric fa...

Thanks for your comments. Yes that is a restrictor in the take-off, it's actually a 0.6mm mig welding tip, I've now taken it out and gettting a very stable reading, it was a bit twitchy before that - the take-off adaptors have a very small hole in them anyway (about 0.5mm same as the standard vaccuu...

It's fitted in this, 1971 spitfire with a 1500cc engine.

Wiring has been tidied up since these pictures were taken and distributor removed and blanked off. The brown wire on the EDIS was for tacho signal but it worked fine with the megajolt signal so also removed that wire. Everything works really well, next project is too add an auxillary input for tempe...

I started this project over 18 months ago but had to put on hold for while because of health problems so last week decided to finish it off:

how true does the edge of the trigger wheel run and can you mount the sensor so it looks at the edge ? it will give you a much cleaner signal, also convinced your gap blip is the screw. Main thing is to get clearly defined pulses and gaps, if you cant mount sensor on edge try current set up but take...

Is that pulley aluminium or steel and is there a gap between the pulley and trigger wheel?
I noticed you have a screw next to the missing tooth and a bit of a pulse in the gap on the scope - I think your sensor is seeing the screw heads.

I've got that one and it works fine with Vista and XP although it's not immediately clear which driver you need for it, can't remember which one I used in the end.

You might want to have a look over here: http://www.sideways-technologies.co.uk/forum/Blah.pl few guys on here with some of the more extreme mods to Spitfires who would be interested in your project.

Not sure about new EDIS connectors but I do know you can't get the pins on their own. However you can remove the pins. Using something like a jewellers flat blade screwdriver lift out the orange rubber seal around the wires, if you look into the connectoryou will see there is a plastic tag holding t...
