Genuine Siemens / Mototron DEKA IV (DEKA 4) High Impedance Injectors

Tuff Car Parts stocks a wide range of injectors. Amongst these is one of the most well respected injectors on the market, the Siemens 80lb long EV1.

This newly released injector is based on the same design as the popular 60 lb/hr DEKA IV injector (FI114961), but with the ability to handle much higher fuel pressures. They don’t exhibit the high fuel pressure handling problems that are typically found with many if not most other high flow high-impedance injectors whilst still remaining linear and controllable. This more consistent behavior will make you tuning specialist smile as fuel trims and the vehicle’s idle character are far easier to tune, resulting in better performance and better drivability both down low in the RPM range and at wide open throttle. This is what makes these injectors very well suited to turbocharged and supercharged applications that experience much higher fuel system pressures.

These injectors flow at an impressive 80 lbs/hr at 43.5 PSI (3 BAR), and of course are able to exceed this at greater PSI. Despite the high flow rate, they are linear and controllable at low pulse widths and have been used in ULEV applications. This allows you to use a larger injector than normally possible without hurting idle and low speed drivability.

Adding to the flexibility of application, these injectors are high impedance making them compatible with most ECUs, whilst delivering the most flow available in a high impedance injector. Historically most performance injectors with higher flow rates would likely have been low impedance injectors. This is because in the older (fat body style) low impedance injectors (think 1980’s and 1990’s designs) had faster opening response times and generated less heat when they were being operated with proper peak and hold injector signals. This meant that at higher flow rates and lengthier duty cycles low impedance injectors would outperform their high impedance counterparts.

Today’s high impedance injectors however are able to outperform those older low impedance injectors at larger flow rates due to their newer designs, tighter manufacturing tolerances and much lighter moving parts. Thanks to this newer technology current Siemens injectors are more linear throughout their pulse range; they are able to repeat shorter pulse widths consistently which means they can provide excellent part throttle and idle characteristics, and operate at higher maximum operating pressures.

The injector connector utilized is the EV1 which is found on many older and late-model OEM applications such as the GM TBI, TPI, LT1, LT4, LS1, some LS2, some LS6 and most European applications. For ease of use we also offer this injector with the EV6 / USCAR connector (MOTR-04560). Purchase only the injector with the connector you need and eliminate the need for in-line adapters or having to change the factory connectors.
