The ID2000 has set the standard for linearity and control in a large injector. Flowing in excess of 2000cc/min at 3 bar, the ID2000 will also provide a smooth stoichiometric idle on small bore engines running E85, and it will do all this while maintaining strict linearity up to 95% duty cycle at 9000rpm. With a pressure capability of 9 bar this injector can flow as much as 3700cc/min with excellent low pulsewidth linearity, and has the broadest operating range of any injector on the market. Follow the shortcut links below for specific information, or scroll down to see all data for the ID2000.
Basic Specifications
Nominal Flow Rate - 2225cc/min @ 3.00 Bar (43.5 psi) Using Gasoline at 52 Degrees C (125 Degrees F)
A Few Interesting Videos
This video from Ed Uksusman at Equilibrium Tuning shows a flawless 750rpm idle on an E85 fueled Subaru.
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.

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.
Dynamic Flow Rate and Dead Time Summary
Dynamic flow rate and dead time values across the voltage and pressure range.
This data is also available in the format required for Ford Factory ECU's (Hi Slope, Low Slope, Offset, Multipliers, etc) GM Factory ECU's (3D Offset, Low

Standard Fitments
Most applications fall into one of four standard fitments consisting of two standard lengths, (48mm or 60mm) and 2 standard fuel rail bores (11mm, or 14mm)
The 3D models pictured below give the relevant dimensions of these standard fitments.
Application specific fitments are also available and are listed on the order page.
