Want to upgrade to an ecu set up either nodiz or megasquirt, have been looking into it and before I order the parts from maybe "trigger wheels" as they are close by. How has anyone fixed the actual trigger wheel to the pulley wheel ? Informative guy at trigger wheels suggests using the pulley bolt and a spacer it will be fine but have seen where it is machined and fitted to pulley and just drilled and tapped also. Our pulley is aluminum but have also a stock steel which I was going to fit. Also what happens with distributor drive once you remove and blank off distributor wont it need securing to stop it moving or am I over thinking.... Looking at running O2 sensor , coilpack, CR sensor off ecu but keeping carbs...
Have you looked at the Mexican bug injection set up as a solution ?? I have and it looks - interesting !
ye I did but not sure I would be able to hook it up to anything and besides the cost is Wow! and plugs, connections are a struggle. can get a nodiz set up for about £400. My old accusparks dizzys have lasted well but need tlc..
I think whatever solution you go for will be £££.... There was a guy selling bespoke kits at VolksWorld starting at 5k , looked good but ... jeeeezz ... I too looked at better ignition solutions , sourced the correct dizzy (034) , bought an 80`s Lumenition unit off a member on here and never looked back to be honest , transformed the tickover and pick-up The 123 seems a good solution but whilst the Lumenition is doing its stuff i don`t see the point ?? Call me old fashioned ...
Not quite sure what the O2 sensor is going to control if you're not going for injection. If the system's just going to be for the ignition, a basic 123 dissy will do all of that and more (and be cheaper).
O O2 sensor wont control owt but we can check settings on laptop and in future go for FI, agree 123 may be cheaper but long term an ecu may or may not be the way to go who knows !!.
What engine? If it's a 1600 wouldn't you be better off spending on the actual engine making it bigger?
I did experiment once with drilling dimples into an aluminum pulley and gluing small magnets into the dimples to make a magnetic timing wheel, using a Hall effect sensor . However before going very far the magnets started flying off as they were too shiny for the epoxy glue.. so that idea was dumped. The O2 sensor is a good idea as it tells you when you are running lean (dirty jets) or rich ( choke on) even on a basic engine..
If your keeping carbs you just need Megajolt kit to control spark . I’ve done one type 1 engine where I made bespoke trigger wheel and my type 4 is running thedubshop type 4 trigger wheel and microsquirt ECU but that’s FI and coil per plug
ha ha ha where would the fun be in that and I would need two bud, I only get to borrow one and thats normally when its broke....
Ignition side - good halfway step. Speeduino. https://diy-efi.co.uk/ The trigger wheel that mounts to the rear of the pulley is tidy. Distributor drive - carefully remove the drive out though the dist. hole, just leaving the cog. on the crank. Magnet to get the washers at the bottom.
