Fuel injectors are not a one-size-fits-all type of product. The right fuel injector must combine the elements of fitment, coil impedance, flow rate, and tuning data into one injector specific to your engine's needs. This is a lot to ask an injector line up consisting of only a handful of options. The right tool, used incorrectly, yields substandard results at best.
Fuel injectors follow this same universal law. Proper data is required for proper tuning. Using the data is easy. Often it is cut and paste from the DW excel sheet to the tuning software.
Development of accurate injector data is a complex process, but there are no shortcuts to a proper calibration. DW has developed specially designed and calibrated flow benches utilizing digital flow meters, which are required to measure the precise fuel mass needed for proper characterizations.
The data acquisition process consists of collecting over data points per injector part number.
These data points cover pulse widths, pressures, and voltages that the injectors will experience once installed in your engine.
The collected data is statically analyzed, scrubbed and formatted into a General Characterization Summary. This Summary can then be formatted into application-specific formats for different makes, models, and tuning platforms. The application specific data is then in-car optimized by one of our tuning partners.
Quality injectors mated to proper calibration data will still perform poorly as a system if the injector set is not properly flow matched. The DW dynamic flow matching process ensures each set works together as a system to fuel your engine properly. Fuel injectors do not operate in a static state so why test them in a static state?
In the engine, fuel injectors are a very dynamic component, constantly changing frequencies and pulse widths to precisely deliver the fuel needed. The DW multi-point dynamic flow testing process mimics these conditions by testing at multiple pulse widths within each of the ranges below….

Fuel Injectors. Dynamic Flow Matching Quality injectors mated to proper calibration data will still perform poorly as a system if the injector set is not properly flow matched. The DW multi-point dynamic flow testing process mimics these conditions by testing at multiple pulse widths within each of the ranges below… Low Range milliseconds — Low pulse widths are used during idle, light throttle cruising, and deceleration.
However, expensive electronic flow meters are required for accurate testing in this range so few companies actually balance their injectors this low. Low pulse width balancing is crucial for a smooth idle on large injectors. Transitional Range milliseconds — The transitional range covers the pulse widths that typically make up the non-linear range of injectors.
Although most DW injectors are linear well into the low pw range, transitional balance is important because many high flow injectors spend a majority of time in this range.You will see the difference on your engine monitor with the very first flight!
Click here to see some before and after test results compiled from actual in-flight data. With the invention of multi-cylinder engine monitors, many pilots started watching an unsettling graphic display of just how far from "optimal" or "uniform" the cylinders were running in their engines.
During a normal lean cycle, such as most pilots routinely perform just after arriving at their crusing altitude, pilots with engine monitors have discovered that the EGT's on the various cylinders will all reach peak at greatly different total engine fuel flows.
At cruise power settings, GAMI engineers have seen some engines in which the first cylinder reached peak EGT at, for example, 15 GPH, and the last cylinder did not reach peak until the engine had been leaned to a fuel flow of 13 GPH or less.
Notice in the discussion above, that the important issue is when in the complete lean cycle each cylinder reaches peak EGT, not the absolute value of any particular EGT.

Many pilots make the mistake of focusing on the absolute temperature of the individual cylinder's EGT, rather than focusing on the sequential timing when the different cylinders reach their maximum exhaust gas temperature. Over the years, a number of pilots and mechanics have attempted, in a rather hit or miss fashion, to play "musical injectors" with their fuel injection nozzles.
This never solves the problem. Some have even tried to alter the fuel flow by drilling out their injectors, or making ill-informed substitutions of different part numbered injectors. GAMI investigated the legality of such efforts. Don't jeopardize your license and your insurance by shade tree engine alterations.
GAMI has developed and certified specifications for a set of precision fuel injectors for almost all engines in the current Continental and Lycoming fleet of fuel injected engines. These specifications are optimized for each engine model, based on the extensive testing with GAMI's state-of-the-art 96 channel data acquisition system. Data, not "hangar talk"! All rights reserved.

Huge Fuel Savings!Bosch fuel injectors have broad market coverage for both OE and after market applications. Fuel injector performance can be affected by particles as little as 10 microns 0. The main causes of fuel injector wear or failure is contamination of the fuel system.
Corrosion due to moisture in the fuel also contributes. These fuel injectors can be cleaned by pulsing them thousands of times while they are in an ultrasonic cleaner.
Afterwards the injectors should be flow tested for spray patterns. Injector flow rate should also be confirmed.

Base Fuel Pressure also: Base Pressure : The pressure to which a fuel system is regulated during start and idle condition.
It is important to note that this value depends on what fluid pressure is used. Diffuser Plate: These plates are visible on to the bottom of many modern injectors.
The plates contain any number of holes of differing sizes and orientations. Duty Cycle also: Injector Duty Cycle or IDC : The time that a fuel injector spends open compared to the total time available two rotations of a four stroke enginetypically expressed in a percentage.
Duty cycle is RPM dependant since the faster an engine spins, the less time an injector will have available to open before the next ignition event. Ferrous Metals : A term used to denote the presence of iron Fe in a metal alloy. In order for an electromagnet within a fuel injector to move the internal valve mechanism, it must act upon a ferrous piece within the injector.
It is these ferrous pieces which are susceptible to corrosion.
Hygroscopic: the ability of a substance to attract and hold water in suspension. Injector Length: Injector length is typically measured from the center of the upper seal o-ring to the center of the lower seal o-ring in most cases. Typical injector heights are 64mm, 53mm, and 38mm between o-ring centers.
These injectors are typically installed in the intake manifold near the cylinder head or in the cylinder head itself, and aimed to spray fuel at the intake valve s. These injectors can be fired sequentially each injector is timed to fire just prior to opening of the corresponding intake valvein batches groups of injectors fired togetheror simultaneously all injectors are fired at the same time.
This type of injection allows the precise and even dispensation of fuel to all cylinders. Pickling your fuel system : Pickling is a slang term used to describe the process of preserving your fuel system components by running some type of preservative fluid regular gasoline in most cases through the system.
This is done in order to displace liquids that can hold water such as alcohol based fuels including E Pulse: One fueling operation for a single injector which typically coincides with the intake stroke of its matching cylinder in a MPI setup.
Pulse width is used in conjunction with RPM to determine the injector duty cycle. Saturated: This signal is used to operate high impedance injectors. Rather than a complicated injector driver signal requiring a mid-pulse reduction, a saturated signal is a simple constant strength signal. Genesis 2. Mini R52R Fuel Injector Clinic Search.
