Interesting thread, thanks to all involved. I am on LS1B COS2 (01290002), so only have B3702 (and B3703) to play with. Conversation seems to have centred on later OSs with B120x (for understandable reasons), but is anyone able to confirm the LS1B tables are indeed in reference pulses (mS vs. milliseconds) as Gelf postulated back on page 9? This seems to tally up with the HPT people, and the 5.55 number that keeps cropping up. It also seems a better (more apt) unit than milliseconds.

For the stock LS1 (2004 Monaro) cam I have:
IVO IVC EVO EVC
377.5 574.5 140.5 347.5

And my cam:
361 583 129 355

So I assume if I want to set injector end to IVO, I want to advance 16.5 degrees, so subtract 0.183 from B3702. If anyone could sanity-check it would be a great help
