Our board has been able to produce a strong corelation for the angle of peak cylinder pressure and the signal processing method has been passed to MK for creation of the code.
While we have had success with the peak pressure the current version of the board is unable to produce the flame progression or the MFB50 angle at this time, we feel that this may be possible to correct with further signal processing or improved hardware.
The DIY hardware is undergoing a revision to provide better protection from ground loops as at present there is a risk of damage to the ECU should the secondary voltage make it back to the ECU.
Further information will become available as things progress, for now the graph below shows the corelation of the angle ATDC of the Ion sensed pressure peak (IC) vs the pressure sensor sensed peak pressure (PC).
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.
