Heres the datalog, was able to get a few WOT pulls from 2500-8400, was fairly conservative because it was raining LOL. Hopefully this looks a bit better.:)

Still quite a bit of knock. I made some adjustments for it, and some fuel adjustments. Take this one for spin when you can and we'll see how it looks. Same datalog and driving style.

Also I can put in the RDX injectors tonight if you’re able to send the data, could be a bad fuel injector causing all the knocks in cylinder 3.:)

Is that what you want to do is switch to RDXs? Your injector duty cycle is only at 75% and it's still really rich at that point. But if you want to switch to RDXs let me know.

I might switch do rdx’s, i feel like the stocks are getting pretty old and maybe the one in cylinder 3 is causing the knocks, also just a supporting mod for the future, woukd be helpful i think.:)

No problem. Here is the first one for the RDXs. Do not run this with the stock injectors, upload it once you have the RDXs installed and ready to start it.

That was my concern. What color are the o-rings on the RDXs? Check out this blog I found, this explains the issues and how to spot the fakes.

Okay. Go ahead and make another datalog with the stock injector tune and we'll see how it looks. And make sure everything is looking good.
Did you put the stock injectors back in the same cylinder when you reinstalled them? If not, it will be interesting to see how the knock looks in this next one.
