Re: Sprut - A newbies try to design an ECU
The best way to do "the self learning ignition table" is measuring "in cylinder" pressure.
(we need to do measure and recognize unneeded spikes during "fire cycle")
Other ways are angular acceleration measurement and/or Ion-Sense.

Re: Sprut - A newbies try to design an ECU
What kind of detonation detection method you can use ..?? KNOCK Sensor ..? Ion Sense ... ?? or angular acceleration computing for the best torque ..?? I don't know if that question was for me, but currently it supports 2 knock sensors for detonation detection, just like the Frankenso. This question...

I'm so busy at this time ... and have no energy to test new firmware and CJ125 WBO2 controllers. (on frankenstein)
