weird timing issues & no power
I recently made a thread about my knock sensor issues and have since replaced the sensor and the sub harness. Butt dyno says I gained 35ish horsepower but the car has since felt sluggish again.
I took more timing logs and I’m wondering what the tuning experts think about these.
The sub harness looks fine from what i can see but maybe it did melt again? I’d have to check but its quite the PITA to get to. Thanks for the help.
Update: my pictures wont attach, see links below for images

Need more information about what exactly you were doing with the engine when you took those readings. Typically I'll do a couple tests, first one I just hold the rpm at like 3k and make sure timing holds steady. Next I'll go for a short drive and pull through first/second gear to redline and check the log to make sure it wasn't pulling timing.
Something is definitely wrong with your car though, it should only be pulling timing back 1 degree at a time when the knock sensor goes off, you're completely losing timing advance. Where did you buy the sensor and sub harness?
