  1. Some default state according to what i based it on. Only just now noticed this utterly disgusting computer seems to have not copy-pasted the rest of neds code. enum warningStates_t {IDLE = 0, WARN_MINOR, WARN_GENERAL, WARN_DIRE}; warningStates_t curState, oldState;
  2. I saw someone who did this, but with ford pickups. It was cert'ed as a body swap. /ling
  3. Umm i can't edit the prior post to have //high is turning the coil on for 2ms and low turns it off & makes a spark. //wait 10 milliseconds then turn the coil on again, saves much battery. I do question why this doesn't compile
  4. Does anyone here know how a 'coil on plug' can sense when a spark has occurred & use that sensor wire thing?
  5. Could someone tell me why this Runs way slower (as in, ignition retarded with the sensors and engine speed the same) and noticeably less smooth than.... This?
  6. If i have a command to run 'void taskname' in the loop, and the 'void taskname' points to another 'void taskname2' or something, will this run? I seem to be doing something wrong.
  7. Picture-less update. While i will still need to dial in the auto-advance curve (the orig' relied on a combination of moving a lever to a basic range, and the magnets on the flywheel ramping up the speed of the points opening) it has a notable improvement in fuel economy, partly due to being able to wind the fuel mixture screw in 1/16th of a turn & have the same performance. It's like having the magneto set perfectly. But requires a battery.
  8. Cheated with opticouple chips to isolate the aruduino from the unbelievably noisy stock system.
  9. Sure... i doubt they'll look though. I should have posted it to the other forum just to get their knickers in a twist. So easy.
  10. Finally. Feels weird driving a car that used to have buzzing points. Now it only has this digital thing running the show. Torn between continuing the coil on plug thing or coding some decent ignition timing for it.
  11. Ardunio nano on a small board with some hall effect sensors. installed in the end of an old can, some melted plastic in the holes, light passes through the plastic so i know where to drill it to put the bolts through.
  12. If it's LED1 you're trying to connect to, that LDR idea i had might be easiest. Looks like connecting things to the LED makes that flasher circuit go nuts. I only know that because i built that flasher a a kid, the rest of the circuit is a bit above my pay grade.
  13. Opticouple. Contains an LED. It might not might one being conected. Or put a photo-resister over the LED. I've done things like that but the calibration is hard to maintain. Phototransistor might work better.
  14. Turns out i need to use the cylindrical style transformers, they need a longer ramp up time of at least 8 milliseconds, ideally 10-12. The little cube ones are nice but they seem to foul. Although the cube style produce a hot enough spark to burn paper & start to melt the spark plug electrodes, when fouled with fuel they can't even light a pan of fuel. The cylinder style build up a charge and discharge it all at once, this appears to help with the 'self cleaning' effect. A big plug gap will make them lag like crazy, but the spark is loud enough to hear from outside the engine block.
