    Timing Correction - Individual Cylinders
    Description: This feature allows for a tuner to apply a constant ignition timing correction for a specific cylinder. Timing can be advanced or retarded. A positive number RETARDS the timing. A negative number ADVANCES the timing.
    Individual cylinder timing correction can only be performed on certain ignition types as follows:
    · Coil On Plug Distributorless Ignition Systems – Full individual cylinder timing is performed.
    · Waste Fire Distributorless Ignition Systems – for these applications, the timing correction is applied to both cylinders paired on a coil. The greater retard of the two cylinders will be applied to both cylinder firings.
    · Points Output – Individual cylinder timing correction is NOT performed on this ignition type.
    Values: Units = Degrees. Range = +/-45°
    Is the above correct for V4? The Help menu contradicts the actual EFI software for advance/retard.

    This was changed in later version(s) of V4. Read "Important Note!!!" on page 5: https://documents.holley.com/techlib...r10864rev1.pdf (Holley EFI V4 Software Overview)
