Samurai Supra Posted March 3, 2020 Report Share Posted March 3, 2020 Hi Chaps. First time tuner here, attempting to tune my Supra on a link plugin with a g4 knock block, (brand new item) I have a set of iPhone headphones which work fine (tested on my phone & laptop), but cannot hear anything on the knock block with the vol on full. I tried a set of elcheapo head phones, getting some noise, it is quite faint and only on one side of the headphone set. I am using a single Bosch wideband bolted between the stock sensors. To test I bolted another sensor to the intake using seperate wiring (the one that came with the knock block), same result. Should I be using better headphones or is something wrong with the knock block? THanks. Quote Link to comment Share on other sites More sharing options...
remski2 Posted March 3, 2020 Report Share Posted March 3, 2020 I found out that recording the audio works much better. Old link manual has a step-by-step procedure how to graph the knock and focus on the areas of interest. http://www.enginelogics.com/wp-content/uploads/pdf/knockblock.pdf (Staring section 3.2.2) You might want to play around with frequency filters and speeds once you have a sample. I had audio split, feeding the Link software and the NCH software but I cant really distinguish the knock by just looking at the Link graph. So now I just record and analyze in NCH only.

Samurai Supra Posted March 3, 2020 Author Report Share Posted March 3, 2020 Thanks. I was considering trying that. Did you find the knockblock audio level low as well? Quote Link to comment Share on other sites More sharing options...
remski2 Posted March 3, 2020 Report Share Posted March 3, 2020 No. Level was good. Hook it up to a laptop and download the NCH software. Make sure its charged if you havent. Maybe thats your problem ? I find it that 1/4 turn on the gain is just the right level in my laptop without clipping the audio. Quote Link to comment Share on other sites More sharing options...
Adamw Posted March 3, 2020 Report Share Posted March 3, 2020 You need to use head phones that have a 3 pole 3.5mm jack, often referred to as stereo. Most smartphone earbuds have a 4 pole plug as they also have a microphone, these won’t work. 1320MINI 1 Quote Link to comment Share on other sites More sharing options...

I did charge it, maybe it was not fully charged, will put it on again. Will try the laptop and a new set of headphones.
