    Whatever pid you wish to view must be in the main channels list.

    If the knock retard channel is not in your channels list it will not populate data in the graphs/charts etc.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    I'm having the same issue with mine. It's reducing the advance, but knock retard shows 0 in the channels the graph and the chart.

    I'm gonna bump up this thread by saying I cannot get Knock Retard to show either, I have it in my channel but I still get 0 like the others. I am still a noob at hp tuners so I'm sure it's something on my end.

    Post a log file.

    You can test the sensors too by smacking the block with a mallet while it's running, it "should" pick up that noise and show something.
