Goldwave can do the same thing - I would recommend AGAINST software like this as it attempts to remove the human element from it. Knock monitoring and center freq. selection involves far more than just a lookup table (which is what this is likely trying to estimate).

Not quite, sir, not quite. Goldwave would be impractical in a tuning session. Does Goldwave filter the audio LIVE, allowing you to hear and see the filtered waveform...LIVE and also set thresholds and allow an audible "KNOCK" sound to be played while you are monitoring other instruments on the dyno?
Not quite. It's not just a lookup table, the resonant frequency can be calculated. Actually much better control over the knock definition than the TPIC8101 chip in your ECU. |

Never seen it before, but that's a cool idea. Would be even better with a way to integrate it with RomRaider logs. Real-time knock detection is sort of interesting, but without knowing the RPM and load when it knocked, you don't know which cells to adjust in the fuel or timing tables.

Yes, I do listen to the live audio when inducing knock to take sound clips in Goldwave. The initial filters I use are set with hardware jumpers on an inline amplifier. I do not rely on software filtering unless absolutely required. Goldwave is used for providing data to your datalogger/ECU (as in, you, the tuner are taking this data from Goldwave and punching it into the ECU software). The ECU is where the heavy signal processing should take place (applying a knock window to eliminate false knock, or a cylinder firing order window for per-cylinder knock using 1 sensor). Quote:

You can't time sync two separate logging systems. This is why people that install AFR/EGT gauges on the dash expecting to adjust the fuel table later when they see a number they don't like are out of their mind. |

OK I read that post. Nice. Finding. What you have found is something this software also accounts for in the high frequency mode Plex knock monitor ($1000) also accounts for this too. Sometimes it's harmonics (2x the center frequency). As per the log sync the software provides system time in the log file it creates, so I believe you can match the log from RR to that of this software. But You will have to select absolute time in RR log settings. There is currently development on this software to get RPM and MAP but not sure about romraider, does romraider have an RPM output via Serial? That should be easy to code in. |

Or you can just use a datalogger that already incorporates the knock signal. No matter how you cut it, this software package is playing catch-up with others that are about a decade ahead in development.
I'm sorry, but matching up a time stamp between 2 independent logs is NOT how you sync them up. If you had a synchronized RPM signal, this would be a good start but you've still got a mountain of work ahead of you if you are trying to do this manually ('this' being, looking at two independent logs and trying to match them up). Or, again, you could just use a proper datalogger that does this all internally. Are you involved in the development of this software? You seem to be fighting pretty hard for them... |

I'm considering using the ELM device as an option to get RPM and map, this however does not work on my subaru (JDM, not sure why) As well as an independent device that will tap into the hardware for map and engine speed. Device is currently being tested, and most of what we would useful for tuning be featured in that version. This will be more useful to the megasquirt / ECtune/speeduino or any ecu usually with no knock feedback. I love your feedback though, Last edited by JMlegacy; 03-30-2018 at 09:26 PM. |

RomRaider is open source and extensible... If this and RomRaider were to communicate in real time you could have a column for it in RR logs.
I think all of the current logger plugins use serial, but you could probably do it with a localhost TCP/IP connection instead. Have this thing listen on localhost:1234, and spit out a stream of "knock count" numbers to whoever connects. |

Hello,
A new release is available. Now there is Boost, AFR and RPM reference. There is a demo download. http://tunernerd.com/download/knock-monitor-pro-demo/ |
