At the moment rusEFI does NOT have any working ion sense hardware or firmware.

|
|
Orchardperformance has some proto hardware he has not yet assembled which might help with signal acquisition. Link TBD.

Q: Is Saab/Mazda smart coil unusual in any way?
|
|
|
|
A: the problem with many smart coils is that you can't apply a voltage/sense current on the primary since it's grounded internally. The mazda/Saab coils have the voltage generation internally.
|
|
|
|
The three pins on bmw are just both sides of the primary, and one side of the secondary (other side on the plug ofc)
|
|
Theyre a normal dumb coil
|
|
All the magic is in the box
|
|
The mazda/Saab coils have the voltage generation internally
|
|
They have gnd/12v/trigger/sense
|
|
here is no magic in the bmw coil
|
|
It's just a transformer
|
|
No silicon
|
|
In my mazda, they cut the BMW box in half: half is in the coil, half is in the ecu
|
|
On Saab, they put half in the coil, and half in the extra module

Simon latest--- Hooked up the Ion board to the R50 coil, connected the lot to a test MRE and will attempt to run a spark with the ion board connected and check the voltages produced, might try to scope the ion output to see if we get some kind of output.
|
|
If I need to I will play a flame over the plug while sparking to have something to pass the ions. |
