About Injectors

The makers of Genesis Injectors reputation as fueling experts is tied directly to their research and product development efforts.

Injector Spray Patterns:

Factory engineers have gone to great lengths to make sure that fuel is injected in the correct spray pattern for each cylinder head design. Meanwhile, tuners have put up with cold start problems, lumpy idles, misfires and other problems for years. A major reason for this is injectors that are mismatched to the application.

Genesis injectors are designed so contact with the metal walls is carefully avoided. An injector that sprays a single-narrow fuel cone will wash down the manifold and head. Tuning/holding precise air/fuel ratios is thusly complicated because fuel puddles and then slowly dribbles into the combustion chamber.

Injector Impedance:

It is also important to understand that fuel injectors come in two electrical flavors -high and low-impedance. VW ECUs require high-impedance but many standalone systems are equipped to manage the lows. The primary advantage of low-impedance injectors is their faster response time. (That is, the speed at which they can be turned on/off.) When very large injectors (e.g. >580cc) are fitted, low-impedance injectors are much easier to tune for proper idle quality and for use at extremely high rpms. The primary advantage of high-impedance injectors is the fact that less heat is generated in the drive circuit and thusly less complex/expensive circuitry is required. Again, if you have a VW ECU you absolutely must use high-impedance parts.
