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?

The photos were taken as i stopped at a red light on the highway, though I understand that doesnt help much. My OBD reader comes on saturday, so I’ll have a 3k reading and a 0-60 pull.

To answer your question, the sensor and sub harness are from Z1.
