Hello, all! I am very new to the DSM world. Bought this car from a guy that was moving out of state. Finished up a few things mechanically and now it is in desperate need of a tune. I've spent a lot of time searching on forums and reading wikis/guides. I know this tune is not optimal, whatsoever. However, the car is drivable. I'm getting lots of knock in lower RPM and I am not sure why. I lowered timing everywhere to try and eliminate knock before proceeding with anything else. There ended up being a few bad sensors, which I have since replaced and captured a new log. Any and all help is very much appreciated! Thank you
