Injector Dynamics ID1050X 1050cc Injector Set (4 Injectors) - To Suit all EJ25 Engines

ID1050X - Nominal Flow Rate - 1065cc/min

*Dynamic flow rates measured at 3.0 Bar (43.5 psi) Using Gasoline at 52 Degrees C (125 Degrees F).


Application specific fitment is handled with the addition of various top hat adapters, and occasional machining operations. Standard fitment exists for most popular applications, and new fitments will be developed on request. All standard lengths and fuel rail bores are currently accomodated.

Dynamically Matched Sets:

We only sell matched sets, and within each set the dynamic flow rate (slope) will vary no more than +/- 1%, and the dead time (offset) will vary no more than +/- 20 microseconds which is equivalent to +/- 1% at a pulsewidth of 2 milliseconds.

It is this dynamic flow matching across the pulsewidth range that separates the men from the boys.

Tight matching at low pulsewidths allows the use of high flow rate injectors without sacrificing idle, off idle, and cruise quality while the matched offsets insure that the individual injectors respond properly to atmoshperic and voltage compensations built in to the ECU.

Full Dynamic Characterization

We provide the data that you and your ECU need to do the job properly.

Flow and offset values are provided from 8 to 16 volts across the full pressure range in 5 psi increments.

Additionally, we publish full dynamic characterization curves: Raw flow vs pulsewidth, offset corrected flow, linearity curves, and pressure sensitivity plots.
