What does the stock timing mark for the leading plugs represent?

example: is it 5 degrees AFTER TDC? or exactly TDC etc?



what is the total advance used by Mazda for the stock engine, and the rpm at which that advance is complete?



Does anyone have an excel or other timing map for a 13bt that i can view without downloading additional software?



I am making a new map next week from scratch and i need some of these values. thanks

 

the marks are 5 and 20, leading mark is 5,



not sure about stock mazda specs i would love to see this myself.

anyone crack that ecu to let us know?

 

i put this in the single turbo section originally as there is more of a technical knowledge there about engines and tuning then just the general 2nd gen section. It seemed more fitting as the timing question is not necessarily a 2nd gen one.



i know alot of the people who can help me with this aren't necessarily 2nd gen people and do not browse this forum and therefore will now not see this thread.

 

nobody really knows what the timing does. it runs more advance than you would with a standalone though

don't worry about it, i've got a decent map now
