The Air Fuel Ratio (AFR) is controlled by how much fuel is delivered to the cylinder for combustion. There are many factors and many sensors that come into play when trying to determine how much ...

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 ...

The terahertz frequency band offers significant spectrum resources for next-generation wireless communications and ultra-high-resolution imaging for non-destructive sensing applications. Terahertz ...

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a stock, EEC-IV engine control module on a Fox Mustang is like trying to stream Netflix on a dial-up connection — outdated, inflexible, and likely to leave you screaming into the void.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

Though the Apple Watch Series 10 is also vying for shoppers’ attention, older Apple smartwatches are still attractive buys at reduced prices. The Apple Watch Series 9 in particular packs a few key ...

Moiré photonic structures permit the engineering of optical band structures and light–matter interactions, offering new opportunities in photonics and optoelectronics, paving the way for new ...

Apple Watch Series 10 comes with the largest screen ever paired with the thinnest design, a new chip, faster charging, and new health/fitness features. Read along for an in-depth look at what’s new ...

The Apple Watch Series 9 is a long-awaited refresh that puts real benefits into upgrading from even very recent models. The Apple Watch Series 9 is the company's best Apple Watch to date and a serious ...

The Apple Watch Series 9 is just like the Series 8 but improves on it in a few small ways: the processor is faster, battery life is Considerably better, the screen is brighter, and you get the new ...

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 ...
