  1. Engine mapping ( fuel if injection and ignition ) just needs an ecu doesn't it ? and a few feeds from throttle position , engine temp etc into the ECU ? CAN bus - what could possibly go wrong
  2. Very similar to ours - started with a 1700 xflow , built them in 1990 SE narrow body . Then changed to the C20 engine , 200bhp , 526kg .
  3. David Not committed , waiting for a cost . Mike's rally car has been fitted with it - in this case no switches required as can program the key pad as required . He's also doing an s3 . I'll wait and see , but costs with standing , can't see any downsides ??
  4. Paul We did the Westfield race series in 1992 (!) - we built 2 off SE's with live axles , raced and drove home from the circuits , then did hillclimbs . Red top Vauxhall - good engines but more power these days . Derek
  5. Great , I’ve booked for that one I think
  6. @barry - mutiplexing and CAN bus are 2 different things . With CAN bus you still have wires to every switch etc they just don't take the full current required for what they switch ( so effectively the CAN bus does the " relay " work ) . Is that correct ? The Lotusbits system includes a keypad that allows switching even if the switches fail . All hidden of course. @fridge - the ignition will be mapped ( ECU) , not the carbs - so you have more flexibilty than just what a distributor can do . I think .
  7. David I have to fit a new loom whatever I do as the original wasn't re-useable . My car will have mapped ignition with carbs , not sure that makes any difference . I think that wiring is fine normally but switches are probably the weak link - also things like the headlight etc stalks that take the full load of what they have to drive . I have negative experience of CAN bus - I have an e46 m3 that I jump started and then took it to 3 different experts to sort it out all the warning lights and the lack of any other lights ( indicators, brake lights , you name it ) . But as I have to have the car re-wired I'm interested.
  8. I'm gutted I missed this - just mot'd the S1 Elise after a covid rest . I've followed this so hope to join the next mtg . Anyone a member of the MAC ? They do a monthly Thursday evening event and also the breakfast club at The World Famous Shelsley Walsh . Some nice cars there .
  9. He's on with an s3 first I think so hopefully will debug it then ! I've not committed to it as I have no cost yet and am already close to " negative equity " on the project . I really can't be bothered with electrical issues . I already have a diva that I've taken to keeping an OBD reader in the boot of ..... and a 1933 Riley I rewired in my youth with all the same coloured wires
  10. Jon Can't help I'm afraid - I have zero ability to tackle this myself so it is being done by the fabricators next to Lotusbits . Same with the radius arms .
  11. it is just the "t" that's being done - proper good fabricators doing it .
  12. I went to see the blasted chassis today and it is a 9 out of 10 . It needs the chassis rail by the exhaust replacing and has had some repairs at the front , lower wishbone mounts . Whilst were at it , will have the lower front bit and the lower backbone base ( which has some jacking dents) replaced before being painted . Also trailing links are splitting due to rust so .... Worth doing .
  13. Been watching your videos and am on a similar journey 👍
  14. I stripped the chassis down , removed all suspension and it has gone to be checked and all suspension components cleaned etc . The body should be going off in a couple of weeks or so - I can't wait . I think I'm around 4-6 weeks off the engine etc and chassis coming back so will then have plenty to do . Leather re trim is about to start, probably ( all stripped out of the car) . The initial gold trim samples are very disappointing - I haven't spoken to the supplier yet but I can't understand why they sent them , So next will be a van load of parts arriving and me getting stuck into bolting it all together . I can't wait ! In the meantime I'll be tending to my vegetables . 🤷‍♂️
  15. I'll keep you posted and start another thread
  16. Sorry , what I mean it that you cannot retrofit it to an existing car - it needs to be fitted from scratch . The 1977 Autocar test I have of the S1 roadtest has the car breaking down several times due to electrical issues . No desire to replicate that . No link - it is being developed by Lotusbits
  17. It's no retrofit ... i have to fit a new loom anyway so this is one option
  18. Good questions . Oil pressure is fine as it is by a pipe , presumably the other feeds go from , for example, the temperature sender into the canbus which reads the current and sends a feed out to the water temp gauge based on how you calibrate it . It looked clever .
  19. Decided that although the chassis looks fine and dandy , with everything else I am doing to the car it would be a bit short sighted ( which i am .. ) to not have the chassis checked for twist etc . I know the car had an accident at sometime as one lower link was bent and a track rod and also it has a rear quarter grafted on ( which I hadn't noticed until the slight difference side to side was pointed out by the body magician . So I'll strip the front down and get it checked and powder coated . Mmmm - going backwards ...
  20. It appears to be a self standing unit that is programmed via laptop . It comes with a multiplexed keypad that can be programmed to replicate the switch functions if , for example a switch fails ... switches etc would only have small current wires back to the canbus .... Is this acceptable ???? ( thought this was interesting in this resto-mod thread )
  21. I'm looking at a CANBUS system for the wiring to ensure reliability . Like you I want a useable car but not the drama elements that I suspect are mainly wiring related in a car rebuilt with new parts. Not going injection thou as I want something with carbs that will occasionally foul a plug
  22. Nothing major to report on mine . I’ve had new joints in the driveshafts and that’s it . I’m expecting most bits to start arriving at the end of the month including the engine ,so hope to be able to start progress again in May .
  23. One of my Airedale's thinks she's a rapper ...
  24. Burg - you are confusing my JPS thread and giving the impression that my car is considerably further ahead than it is by showing your progress . You are depressing me lol
