One of the most important measurements we make while tuning an engine is finding out what the actual balance of air and fuel was inside the engine. It doesn’t matter if we have a carburetor, port ...

If you build engines, tune cars, or even just like mashing your foot on the throttle with conviction, you’ve probably heard the term “wideband O2 sensor” being thrown around at the track, dyno ...

In a performance application at wide open throttle, the ECU needs to control the air to fuel ratio to hit a small target somewhat richer than stoichiometric. The narrowband sensors most OEs use only ...

Tuning a stock, EEC-IV engine control module on a Fox Mustang is like trying to stream Netflix on a dial-up connection — outdated, inflexible, and likely to leave you screaming into the void. For me, ...

It reads the EMU CAN Stream and decodes it into something useful. This works with any CAN enabled device, MCP2515, Teensy, ESP32, STM32, Arduino UNO R4 and more. In the EMU Black, set the CAN-Bus ...

Abstract: We present the design and testing of a 16-bit frequency to digital converter, based on AT89C51 micro-controller, for use in sensing applications. The system generates digital equivalents of ...

It’s taken some time, but the diesel world appears to have reached consensus on how to meet the Environmental Protection Agency’s (EPA) 2010 NOx standards. EPA 2010 was a major milestone in diesel ...

Back in the day, if you were setting up a car with non-stock carburetors or a modified fuel injection system and needed to dial it in, you used old-school methods. If it made your eyes water, it was ...

The carburetor was invented well over a century ago and served the internal combustion engine well. Later, electronic control was married to carburetors with so-so results. Okay, the results were ...
