Every fuel injector type has a unique minimum injection time and latency for it to fully open once energized.
This latency is often referred to as injector lag, dead time, offset, or delay (ip_ti_add_dly__vb).
It is strongly dependent on the supply voltage and therefore stored in an interpolated table.
The minimum injection time is also important to make sure the injection pattern is clear and complete. (c_ti_min_iv). Minimum injection time is calculated by subtracting the dead time at 14v from the minimum pulse width.
All values here are meant for the standard fuel pressure of 3.5 bars (50.76 psi). The flow rate for different pressures can be calculated here: Injector Calculator
The voltage describing Y-axis ldpm_vb_1 is also used for the ignition coil charging Dwell time tables ip_td_*. Be careful with changes to the axis values!
ATTENTION: The conversion factor of the old definitions files is wrong. Correct conversion factor for injector deadtime is "X * 0.032", resulting in a range of 0.00ms to 8.16ms.
