Need to know about Timing

[Blown99]

Old school timing adjustments were done "Seat-Of-The_Pants". Adjusted till you felt it was right.

Is this still the same way with the LS2? I know it has Knock senors, but do you adjust the timing up till you see knock and then back off. Do you have to do this for all of the cells in the timing chart? Or is there some fantastic PID that can be watched on the notebook like STFT VE adjustments and see where it needs to be and set it.

Since my hearing is not what it used to be, (too much time next to the jets in the Marine Corps), I would prefer something alittle more realible than my ear.

The best way to do it is on the dyno. You are looking for MBT or the minimum timing for best torque. Advance until torque doesn't go up or has a minimal increase for every load and RPM point. Be careful to listen/watch/read plugs for knock if there is a possibility the setup could be octane limited.
