Default Timing Curve w/o Knock Sensor Plugged In ?

Hi,

I want to know if anyone has logged their ignition timing on a DE G/Z with their knock sensor unplugged at WOT over the RPM range.

I'm looking for a detailed description of how the timing fluctuates or better yet, a graph of the timing curve.

Thanks,

The knock sensor stops reading over 5500rpm? I believe so I dont see the benefit. Why would you ever unplug the knock sensor though?

Ah, didn't know it stopped reading it post 5,500.

I wouldn't unplug it on a car that I was tuning, I wanted to get an idea of what the ECU does when there is no KS signal. (Ie bad sensor or bad connection).

Only logs I have on hand are from a friend's 02 Maxima VQ35DE, logged with e-Manage, no tuning. Below are the data points he found.

2000 RPM = 3.4 degrees
2500 RPM = 7 degrees
3000 RPM = 7 degrees
4000 RPM = 7 degrees
5000 RPM = 10 degrees
5500 RPM = 10 degrees
6000 RPM = 16 degrees
6500 RPM = 20 degrees
