LD9 NA timing tables.
Saturday, October 26, 2013 7:08 AM
I have been running the HO tables plus 3 degrees, and copied the HO table to the LO table, and removed 2 degrees across the board. I also smoothed both tables, and filled in the gaps manually where needed. I have noticed I have a much improved mid range, but I can not tell any difference at all up above 4,500RPM. I'm running 93 or 94 octane and the car isn't knocking at all.

I also have a slightly desensitized knock sensor. I think it is 20% less sensitive. I was getting 1-2 degrees of phantom knock at 4,000-4,500 RPM before I desensitized it. "No mater the load on the motor. Also race gas didn't change this at all." This was also before I touched the timing.


What is everyone else running? I do not want to go much of any higher until I get on a dyno. Also, does anyone have the stock values for an LG0 or W41 motor?
