Fine-Tuning Your Fuel Delivery for Peak Performance

Achieving optimal engine performance with a mechanical fuel injection system like the Terminator involves precise calculations and careful adjustments. The fundamental principle is to determine the exact amount of fuel your engine requires and then match the nozzle size to the desired operating pressure. This is a mathematical exercise, but simplified by available resources and expert guidance.

One common area of adjustment is the barrel valve, particularly for achieving the correct idle mixture. A good starting point for the barrel valve adjustment is around 20-25% leak down. From there, fine-tuning involves a technique often described as 'whacking the throttle'. You would lean out the mixture incrementally until the engine momentarily stumbles when the throttle is rapidly opened, then richen it slightly until this stumble disappears. This method allows for precise adjustment of the off-idle and low-RPM fuel delivery.

While spreadsheets are available online to assist with pill and nozzle selection, the simplest and often most effective approach is to directly contact Ron's Fuel Injection for personalised advice. Mechanical fuel injection, despite its perceived complexity, is often considered simpler to tune than carburetion once the core principles are understood. The process primarily involves finding the correct nozzle size for your specific engine and operating conditions, then selecting a 'pill' that provides a ballpark fuel delivery, and fine-tuning from there. It's largely a matter of precise calculations and methodical adjustments. Beyond nozzle and pill selection, the only other primary adjustments are the throttle blade opening and the barrel valve setting. Some advanced systems may incorporate additional idle check and high-speed circuits, but it's crucial to establish the foundational settings correctly before delving into these more advanced adjustments.
