Ok well just looked over my log.seems less sparatic now for sure.only pulled timing due to my own stupidity in non boost regions where I had way too much timing. Otherwise it is tons better and not pulling timing randomly

Basically.I used ghe data from a 01 2500hd lq4 pickup since the knock sensors and my motor came out of one. Im possibly gonna log a tiny bit tonight to see if my timing changes fixed the issue so I know whether or not the data works

I just pulled that tune out of holdencrazy to compare thresholds. Those thresholds in that LQ4 tune are significantly higher than even an 02 Fbody tune that has the spark reduced. I would suggest lowering them a bit and see if it makes a difference. You want the thresholds just below where you would actually see real knock if you were getting it.

Thanks for the tip. Still learning how this all works. Got everything down but the timing portion mystifys me
