The ID1600 fills the gap between the ID1000 and the ID2000, and is a drop in replacement for older EV-1 style 1600cc injectors. Unlike the older technology, the ID1600 has a very gradual rolloff into the lower non linear range, with none of the rollercoaster response caused by undamped pintle bounce. This smooth response makes for easy idle tuning, even on small displacement motors. In addition to the excellent response, the minimum usable fuel volume nearly matches that of the venerable ID1000, which means if you could make it idle with an ID1000, you can make it idle with an ID1600! (Check out this article for a more detailed description of low flow capabilities.) With a pressure capability of 9 bar this injector can flow as much as 2700cc/min while maintaining control and smooth response. Follow the shortcut links below for specific information, or scroll down to see all data for the ID1600.
Basic Specifications
Nominal Dynamic Flow Rate - 1640cc/min @ 3.00 Bar (43.5 psi) Using Gasoline at 52 Degrees C (125 Degrees F)
Explanation of Dynamic Flow Graphs
The critical dynamic flow characteristics of an injector can be described with three basic graphs. These are Uncorrected Flow vs. Actual Pulsewidth,
Corrected Flow vs. Effective Pulsewidth, and Linearity Deviation vs. Actual Pulsewidth.
Effective Pulsewidth is the final pulsewidth calculated by the ECU prior to the addition of the dead time compensation.
Actual Pulsewidth is the pulsewidth delivered to the injector and is the sum of the effective pulsewidth and the injector dead time compensation.
Uncorrected Flow vs. Actual Pulsewidth - This graph shows the dynamic flow vs. actual pulsewidth across the voltage range. The Y Axis is flow
in
units of cubic centimeters per minute. The X Axis is actual pulsewidth in units of milliseconds.
All dynamic flow characteristics are generated from this raw data which clearly illustrates the non linearities and voltage sensitivity of the injector.
Corrected Flow vs. Effective Pulsewidth - This graph shows the dynamic flow vs. effective pulsewidth across the voltage range. The Y Axis is
flow in units of cubic centimeters per minute. The X Axis is effective pulsewidth in units of milliseconds.
This curve represents the response of the injector with proper dead time compensation, and at the end of the day this is the one that really matters.
Linearity Deviation vs. Actual Pulsewidth - This graph shows the deviation from linearity (Straight Line Response) across the pulsewidth range.
The Y Axis is flow deviation in percent. The X Axis is actual pulsewidth in units of milliseconds.
All tests are performed at 100hz using a Motec M800 ECU. It should be noted that even though 10 milliseconds represents
static flow, the Motec drive circuit requires that the injector be turned off for at least .5msec per cycle which limits the actual duty cycle to 95% at
100Hz.
This is clearly illustrated by the flat response of the curve above 9.5 msec. 
Dynamic Flow Characteristics - 4 Bar (58.0

Dynamic Flow Characteristics - 6 Bar (87.0

Dynamic Flow Characteristics - 7 Bar (101.5
psi)
Dynamic Flow Characteristics - 8 Bar (116.0
psi)
Dynamic Flow Characteristics - 9 Bar (130.5

Maximum Linear Duty Cycle
The Maximum Linear Duty Cycle Graph shows the maximum duty cycle that can be achieved while still maintaining linear output. Note that this value is both
RPM and firing arrangement dependant.
This graph applies to all Injector Dynamics Injectors.
Pressure Sensitivity Curves
The pressure sensitivity graph below shows the dynamic flow increase vs. pressure using 3 bar as the reference. The tests were performed at 14 volts
with a 5 millisecond pulsewidth, and clearly show the effect of increased dead time on dynamic flow. The theoretical flow increase is plotted as a point of
reference.
