You should let the distributor fire the coil itself until you get the injection working properly. Or is that what you meant?

yes. The distributor will auto fire at constant failsafe 10 degrees timing, if it receives no signal from the 1986 ecu.

sad news..

You could, but it's always going to be shit, and it's non-trivial to implement, so the reward:effort ratio would be crappy.

ok finding most of the parts through mouser

the only problem is this resettable polyfuse 8volt and trip at .5 amps

http://www.digikey.com/product-search/e ... -1480-1-ND

http://www.mouser.com/Search/Refine.asp ... E+0.50A+8V


can i use a 6volt fuse instead? I believe both of them are tied to the manifold absolute pressure circuit, and the throttle position circuit


also on page 2 of the pdf https://github.com/DeuceEFI/Jaguar/blob ... f?raw=true
whats PLL circuit? that connects to pin 44 45 and 43

Lastly what is the "Ferrite 1.5A 40 Ohm 0805 SMD" go to? I cannot find it in the schematics

You can bridge out the fuses if you want. Some people would prefer that for voltage fidelity anyway.

PLL is CPU clock stuff.

Ferrite is USB UART IC decoupling.

I can't find the even tooth decoder in the codebase. I would really like to test and run the project at first with an even tooth decoder, and then move onto installing a 36-2 trigger wheel on the crankshaft with hall effect sensor.

There are these decoders:

  • EvenTeeth-Xand1.c Requires a sync, the '1' part, to operate, uses only one edge, assumed for VR use.
  • HallOrOptical-Distributor-XofY.c Requires a specific usage definition, giving a single fixed angle for open, and closed, and a number of events.

Which means that:

  • The former can't be used on that, without a second sensor picking up a sync point.
  • The latter can't be used on that, because you said the gaps/solids are not consistent around the disk.

If either of those reasons are not a factor, then you can use the associated decoder.

thanks fred
i want to use whatever works
preferably diyefi

but to install a trigger wheel on the crank is going to be really tough
there is 2 cm clearance from the harmonic balancer to fan blades (attached to water pump?? on engine)

i don't see any mounting holes on harmonic balancer
harmonic balancer bolt is inset ?4cm? so a flat trigger wheel can't be installed with a bolt because that would be more than 2 cm and the fan would be hit

i want to prototype first with a syncless decoder.

If that thing is even, the second option will work. But you need to supply the angles...
