How to de-pin E-TEC injector coils E-TEC coils which are pinned into the E-TEC injector plugs can be de-pinned quite easily. The  plugs are TE Connectivity Super Seal plugs and are weather proof. Step 1: Remove the anti-backout plate. While there is a specialized tool for this, a regular hooked pick or an eyeglass screwdriver […]

After cleaning and Port Injectors testing injectors if the results are not perfect, some wonder if the injectors Ok to use? Understanding the reports is key and this guide will help. A sample report is at the bottom. For any engine management system using sequential fuel injection, tighter matching helps ensure each cylinder gets the […]

  It’s important to understand that the coefficient file required by the Evinrude EMM is unique to each injector. When replacing an E-TEC injector, you must update the EMM with that new or used injector’s specific coefficients. You can retrieve the coefficients by scanning the QR code on the injector tag; however, those values represent […]

Some key facts about Ski-Doo E-TEC injector O-rings and gasoline. Gasoline Freezing Point: While it begins to thicken or turn gel-like around -40°F, it requires severe, arctic-level cold (or lower) to freeze solid. Choosing between Nitrile, Viton, and Fluorosilicone O-rings typically depends on the operating temperature and the specific chemicals or fluids the seal will […]

If a fuel injector measures 0 ohms resistance when checked with a multimeter, it usually means the injector has an internal short circuit the coil inside the injector is shorted. What It Means Electrically: A normal injector has some resistance because of the coil wire inside. 0 ohms = short circuit, meaning the coil is […]

Evinrude E-TEC Software When changing Evinrude E-TEC injectors, it can require updating the Engine EMM with coefficients for the new injector. To Update the Engine EMM with the new coefficients, it requires the Evinrude software which can be quote expensive. It seems there are other options… We have a customer who is an Software Engineer […]

Testing a Gasoline Direct Injection (GDI) injector on a machine designed for Port Fuel Injection (PFI) injectors is not recommended due to significant differences in their operating principles and requirements.

Piezoelectric injectors and GDI injectors (Gasoline Direct Injection injectors) are both types of fuel injectors used in modern internal combustion engines, but they differ significantly in terms of technology, performance, and functionality.

Fuel injectors play a critical role in modern internal combustion engines by delivering fuel to the combustion chamber in a precise and controlled manner. They are part of the fuel injection system, which replaces older carburetor systems.

Gasoline Direct Injection (GDI) injectors work by delivering fuel directly into the combustion chamber of an internal combustion engine, rather than into the intake manifold as in traditional port fuel injection systems.

The Mercury OptiMax air/fuel injection system, known as Direct Fuel Injection (DFI), works by using a combination of air and fuel to improve combustion efficiency and performance.

Piezoelectric fuel injectors use piezoelectric materials to precisely control the injection of fuel into an engine's combustion chamber. These injectors are commonly used in modern diesel and gasoline direct injection (GDI) engines, where high precision, speed, and efficiency are required.
