I don't wouldn't say this is just about static timing, nor that anyone has regarded the piezo as "junk". This has centered on whether a single absolute setting (e.g. 12o BTDC) can be best - across engines -... or if "best" varies by engine and can only be determined by performance.
The core counter argument was talk around the difference between injection timing and combustion/flame front, and hence implying you can't use a static timing setup for anything useful due to these differences in different engines. So that argument wasn't just against pulse adapter, but but indirectly against all static timing methods. You went on to say static timing is moot, how is this not an argument against static timing?!?!
It's doubtful that anyone has recorded a dial-position after setting an IP by performance, because it wouldn't be particularly relevant to another engine.
Not sure about nobody recording a dial position after setting by performance. Surely its not just about being relevant to other engines, but also about being able to return straight to that sweet spot.
Also, if nobody has recorded these settings after setting by performance, then nobody can argue that libbys assertion that the sweet spot will usually be half a * off from 12* is wrong!! Thats why Im asking, in the real world, how far from 12* was YOUR engines sweet spot. Is 12* a brilliant starting point? IS it almost always on the money? We dont know, because only Libby has posted figures. Everybody else has rushed in to argue against, but nobody has actually stated any alternative numbers.
Setting "Best" by performance is often regarded as unique to any engine and a measurement of static timing is moot - reference marks scribed on the IP and bracket are faster/easier to use as relative reference (faster than a piezo).
You say setting best by performance is unique per engine, but you're not saying anything new, you're just echoing what has been said here a 100 times already. What we really want to know, is HOW unique. Surely you agree that this is significant?
And timing marks scribed on the bracket / pump body are useless if you switch out injectors for ones with different break pressures, as the timing will have moved as a result (the pulse adapter wouldnt suffer this tho!). What about when fitting a new pump? Or a modded pump? Or a new bracket? Lots of reasons to want a static timing reference (hence people buying and using timing dials!) where marks on the bracket aren't useful.
This thread was started to make it easier for people to use the pulse adapter system, instead its full of people implying its pointless and that libby is full of it. Nobody has yet demonstrated how pointless, by offering up figures different from libbys. Nobody has disproved the +/- half a degree from 12*, and nobody has offered any data to suggest it is greatly varied. Libby has backed up what he says is a worthy method, with numbers. Those that say otherwise should be putting up numbers too.
