Jonathan, the lumy-mag has the same specs as anything else for the pulse method. If you have a luminosity probe that is any good it can also do the luminosity method. The spec there is 1.5*ATDC at 1400 rpm at least that's what Haynes says, and that's where I had the timing on my old pump. Seemed to work well till that pump died.
