12200411 Timing Advance Impass Reached

[Fast355]

02 are the same

I remember something Ed Wright posted about timing limits on 4.3L.

I can tell you that the MBT table has nothing to do with it. I think the OS has another setting for HVS system

Never heard of HVS before. Its also definately a 5.7 calibration. The 4.3 can take more advance because the spacing is wider.
