  1. I'll post more pics once I make some progress. Hoping to meet with my tame TIG welder fairly soon and then I can get all four injectors properly mounted (they're Bosch 0 280 150 716 from a BMW E28) - we can really get going then!
  2. That is indeed what I am working on. Got it running today after a fashion - complete bodge up of the fuel and electrics (using 1 injector per pair of cylinders at the moment...) but was nice to know the carbs were effectively out of the loop, despite still having air passing through them but the fuel is mixed (I say mixed, it's probably just dumped) after the carbs...
  3. Wasn't sure how I was going to get a fuel rail made to fit my installation so looked at ways of directly connecting the injector to a fuel hose. After a bit of research, found these in the USA: Cost seemed a bit excessive and that's before I'd have to get them shipped over but a bit of measuring and lathework later and I'd modified a PCl bayonet to do the job nicely: Has the advantage that I can connect direct to an air hose and blow any crud out if needs be!
  4. Tried it today - it overloaded the carbs but at least I got some of the fuel plumbing underway...
  5. Just bought a neat little fuel regulator off eBay that should be suitable for my purposes. However, seeing as I haven't got all the bits needed to install the EFI yet, I thought I'd do it in stages: 1) run the MS with ignition only (I've already got MegaJolt running fine, so that should be a simple wiring job) 2) install the high pressure fuel pump and regulate it to run the existing carbs Now, assuming the regulator can regulate low enough for the carburettors, can I just connect the end of the existing fuel line to the fuel rail connector on the regulator (with the return as normal)?
  6. I contacted the seller and it's the only one he's got so chances of getting a replacement are pretty slim. Think I'm just going to go with a 12V one (just bought a used Bosch one today) running off a dropper
  7. Just an update, more for my own benefit really. The Bosch 9580234005 is a 24 volt pump, as used on the Alvis Hagglung BV206 - they're about £100 which isn't too bad considering...
  8. It is annoying that volts and valves have the same abbreviation! I've looked at both of those options before... The advantage of fitting a battery balancer is that I can just install the MS like it's in a normal vehicle, without having to worry about relays with different voltages etc. It also means that replacement fuel pumps etc. are easy to come by
  9. Interesting. The problem with my exhaust is that despite being an inline 4-cylinder, it has two manifolds that end up like an over-and-under shotgun until you get to the rear silencer (there's a heat exchanger first) - could I weld the bung into just one of the pipes or would that be a bit pointless?
  10. I'd love to use a 24V pump. Problem is, most 24V vehicles are diesel and as far as I'm aware, you can't pump petrol with a diesel pump (because they're lubricated by the fuel). The existing fuel pump is just a low pressure job. Current plan is to fit a battery balancer, something like this: http://www.sp-shop.co.uk/Sterling-Power-24v-12-12v-Battery-Balancer.html This will enable me to run larger 12V loads directly from the battery but keep both batteries fully charged. Currently trying to find a scrap vehicle in the local area that still has the bits on it - think I've found a BMW E28 not far away that should provide what I need...
  11. Can I install without ever using an O2 sensor then? The exhaust system on mine will make it very difficult
  12. The MegaJolt is 12V and I'm running this, along with EDIS and the coilpack off a converter. For EFI, I have to include the fuel pump and injectors, the pump being the main load. My fuelling issues at the moment are caused by damage to the idle mixture screw seats - they're not sealing so letting too much fuel through at idle and making it run incredibly rich so the plugs foul sooty black in seconds. Trying a quick fix using high temperature epoxy but not confident that will work (and already ordered the MS anyway)!
  13. I'm the proud (sometimes) owner of a Steyr-Puch Pinzgauer. I had a lot of ignition problems, due to condensation/moisture in the distributor so eventually fitted MJLJ which worked fine for a while until I managed to damage both carburettors beyond economical repair. Thinking that since I've already got the 36-1 trigger wheel/sensor, EDIS and coilpack installed and running fine, going the whole hog and installing EFI would not be a massive leap. Have arranged to obtain some Bosch injectors & fuel pump from a BMW E28 and planning on making a custom fuel rail/dummy carbs to connect it all up. The main problems I foresee are trying to fit an O2 sensor into the exhaust system and getting a 12 Volt EFI system running on a 24 Volt vehicle Have ordered a Microsquirt ECU from the USA (getting a friend to collect it), which comes with an O2 sensor and bung Exciting times ahead, I think...
  14. Check your throttle linkages/cables are free - could be a slack return spring. Can you hook the pedal up with your foot the next time it idles high to see if that makes a difference?
  15. Just bought a set of ignition terminals etc. off Nigel to convert my existing HT leads into ones that will fit an early EDIS coil pack. Whilst waiting for them to arrive, I thought I'd see if I could dismantle the original ones that arrived with my second-hand coil pack (leads chopped off). With a bit of silicone lubricant and a small screwdriver, they come apart fairly easily and assembling them again was child's play! I wonder if he'll give me my money back!! (only joking, Nigel, I'll use your to make a spare set of the right length)
