Paul M Posted June 13, 2014 Report Share Posted June 13, 2014 My understanding is that one requires a bosch knock sensor (or similar) and the knockblock and set ecu settings to ON-DI Knk Interface? So what is the ON-Knk Internal knock setting in the ecu and what is required to get it to work? What configuration is best, easiest to setup for reading knock? Thanks!

Simon Posted June 13, 2014 Report Share Posted June 13, 2014 Hi Paul Which G4 model do you have Plugin, Storm, Atom or Xtreme? Quote Link to comment Share on other sites More sharing options...
Paul M Posted June 13, 2014 Author Report Share Posted June 13, 2014 Simon, It's a G4 xtreme Just weighing up my options, what can I do, btw it's a 13B engine Quote Link to comment Share on other sites More sharing options...
Simon Posted June 16, 2014 Report Share Posted June 16, 2014 The Xtreme has on board knock so with the addition of a bosch sensor this can be wired directly to the ECU. It is of the slightly older knock style but still works well. If you are after it more as a tuning tool then the KnockBlock is a better option as it will allow the use of headphones.

Paul M Posted June 16, 2014 Author Report Share Posted June 16, 2014 Sounds good! Do I need a specific bosch knock sensor, which sensor is best for this application? Quote Link to comment Share on other sites More sharing options...
Paul M Posted June 18, 2014 Author Report Share Posted June 18, 2014 What's the difference between the RX7 sensor and the 'bosch' sensor? Does one work better than the other? Quote Link to comment Share on other sites More sharing options...
Simon Posted June 18, 2014 Report Share Posted June 18, 2014 Only reason to recomend the Bosch senso is that it is the one we have had the best results with. You could certinally try the factory RX7 one. Quote Link to comment Share on other sites More sharing options...
Paul M Posted June 19, 2014 Author Report Share Posted June 19, 2014 Based on what test results did the bosch knock sensor out perform other sensors, say the EVO and WRX where in the PClink help files 'Suggested Knock Frequency Settings' you state 13kHz for the EVO and WRX and for the bosch 6kHz? Basically what the differences between a good knock sensor and a not so good knock sensor? They are both just a knock sensor, all work the same in principle, just like a temp and pressure sensor.What really matters is the software and how efficiently and reliably it processes the inputs.

Simon Posted June 19, 2014 Report Share Posted June 19, 2014 Some factory sensors have inbuilt filtering, others are second harmonic sensors such as the EVO one you mention. No problem using a filtered first harmonic sensor but on the G4 Xtreme we are not able to take a second harmonic input. The Bosch sensor seems to have the best ability to cope on a broad range of engines. Quote Link to comment Share on other sites More sharing options...
Paul M Posted June 19, 2014 Author Report Share Posted June 19, 2014 So the bosch is a lot more versatile and the factory knock are specific to application Both are good Thanks so much for your help Quote Link to comment Share on other sites More sharing options...
