Hey guys I was just wondering if you new what the sub settings did one the smarty for our VP trucks. I know that the timing one adds more timing and Torque managment is technically low boost fueling.. But what about duration?

 

I would like to think that more duration would just mean more fuel. I don't know what else it could do.

 

Yeah it has to do with injection duration. The higher the number the longer the injectors stay open longer

 

And it will have to increase the amount of fuel as well. It's not like the injectors open less, for longer.

 

This all depends on the truck or should I say the VP.Some trucks show a increase in power and some don't. This only from what the dyno and 1/4 mile times I have seen.

 

Sry thats what i meant. I dont know what the F*** i was thinking when I typed that crap yesterday afternoon
