I am an LT1/LS1_edit guru and I want to start tweaking my cars tune. But I am not certain the tune it has now is factory. There are a few timing curves that look a little weird. Does anyone have a stock 2001 Z06 file I can look at to reference?

Thanks,

If you still have the original PCM version it is time to get it flashed and updated(I didn't get mine update till last summer). After the car relearns its environment that would logically be the baseline you tune from.

I am more looking to see the stock fuel/spark curves as well as a few other things such as the cooling characteristics and the ignition retard values. I just got an 01 and 02 stock file from LS1edit.com. I do not plan on using these files, I just want to reference them to see what was changed in my current PCM by the previous owner.

What do you mean I should have my PCM updated? I have heard elsewear about the 01 Z06's needing a PCM reflash by GM to update something. Can anyone shed some light on this subject?
