Thread: ACCEL ASYNC PARAMETERS, please explain.

By adjusting this "BASE IPW ECT TABLE - Sets async_accel_base_ipw_ for AAIPW calculation. AAIPW is higher at lower ECT."

What does this actually do?

Not after G33K speak, just the facts in real people words.
By increasing the value say from 4.56 to 5.38 does that increase the amount gas delivered / the amount of time before reacting / time after reacting / of the timing of the injector acceleration?
Or if not, then WHAT?

The reason being, with larger injectors (potentially more lag / latency) should this factor be increased or reduced to ensure that there are no lean spots when hitting the go pedal?

This sets the base injector pulse width (IPW) for the asynchronous accel injection.



Increasing the value from 4.56 milliseconds (msecs) to 5.38 msecs would increase the amount of time the injector is open by 0.820 msecs.



If you increase the injector size, you would change the injector size factor (under the FUEL TRIMS tab) which would compensate for the added fuel without having to change the values in the BASE IPW ECT TABLE.

If the larger injectors have a different latency, you would change the values in the INJECTOR BATTERY OFFSET table (on the same screen as the INJECTOR SIZE factor).

FANTASTIC!

Thank you!
