TCINJD scalar

This just says sec as the measurement and does not say the metric in the comments either.


It seems to be set to .5 in most the stuff Ive downloaded from here. Which seems really high for an injector dead time if it is seconds.

tc is time constant

thats for filtering the injector timing running value and has nothing to do with the offset.

fn367 is the offset

So TCINJD isnt the time constant for injector delay that the offset is added too based on the voltage?

No

its for injector timing has nothing to do with the offset

Would you be willing to elaborate so i can better time injectors to big cams?

yep no problem

the time constant is not the injector timing nor offset. It doesnt require any adjustment.

For injector timing theres a table. Set the injector timing table to your desired ending cam degree to finish the injector pulse length. Exhaust stroke starts the cycle i.e. == 0 cam degrees.

Might as well just set it to all 500s and call it done.

Whats the functions name?
Only thing Ive ever found was the offset table.

Yeah im fairly certain that one isnt on my XDF.


If you get a chance I really need to fiddle with it, fairly certain im blowing fuel on my HEGO at idle lol.
