please explain

[HINDZY]

hi could somebody please explain the table B3702 in cos5
thanks

[TAQuickness]

This show's as the injection timing table:
"This table will offset the actual opening of the injector referenced to the reference pulses and engine coolant temperature."

This allows the PCM to alter the timing of when the injector opens based on coolant temp.

[HINDZY]

"referenced to the reference pulses" i don't fully understand this

what are the reference pulses? are they from crank angle sensor?
im probly way off here but i thought the injectors would open at a point if reference to TDC intake and possibly change with RPM

[joecar]

Referenced to the crank sensor pulses (the ones that indicate crank position... i.e. where each piston is wrt TDC).

[HINDZY]

yep ok so are the figures in this table from TDC?
sorry if these seem like stupid questions im just trying to fully understand
thanks

[joecar]

It's either from TDC or some offset from there (such as IVO on the stock cam)...

I don't know exactly... I can't find any specific mention in the literature.

[HINDZY]

oh ok thanks for your help

[joecar]

It is most likely the offset from TDC.
