How Electronic Fuel Injection (EFI) Works

 · For the most part, motorcycles and carburetors have come to a parting of the ways. While a few carburetor-equipped bikes are still on the market, the vast majority of street bikes are now equipped with some form of electronic fuel injection, which despite the complication it adds, is both a better way to go, and undeniably here to stay, protests from the Luddites notwithstanding.

 · This happens quite often under high load at WOT. ... (if not all) self-learning EFI systems store the new air-fuel ratio tune to the ECU when the engine is shut down. Then the process starts all over again because the leak in the exhaust system is still fooling the WBOS, each time the engine is operated and then shut down, the new, richer self.

Lastly, some modern cars are now using air injection pumps to introduce fresh air into the exhaust stream in order to reduce exhaust emissions. This fresh air can also easily fool the oxygen sensor into thinking the engine's actual air/fuel ratio is leaner than it really ….

Electronic Fuel Injection Tuning Tips For The LS Engine

 · Wide-open throttle tuning is the easy part. A naturally-aspirated engine safely produces maximum power when the air/fuel ratio is approximately 12.9:1; depending on boost levels, turbocharged and supercharged engines respond best to air/fuel ratios between 11.5:1 and 12:1.

 · Happens about 20-30% throttle, under load then goes away. I've attached a link to a YouTube video I made of the noise. You can hear the hissing, as I periodically accelerate. It goes away as I accelerate past 30% throttle. The engine is a 8.5:1 mild 350 Chevy. I'm using a throttle body MPFI HP system with Holley's intake. 14" open element air.

Return Fan and Exhaust Fan Economizers and Building

An exhaust fan economizer consists of an additional fan mounted in the AHU or rooftop economizer section (see Figure 2). This fan discharges air to the exhaust duct, or in the case of a rooftop unit, directly outdoors. By monitoring space pressure, the exhaust fan is used to balance the amount of air exhausted from the space with.

Engine Tuning: Forced Induction Guide

 · Dumping metered air back to the atmosphere results in a rich condition as the PCM assumes all metered air is actually going into the engine. As engine speeds increase, boost pressure at WOT also increases, resulting in loads exceeding . Load continues to increase all the way until redline unless otherwise restricted.
