Apexi SAFC II



The second-generation S-AFC is a fuel computer that adjusts fuel/air ratio by modifying the air-flow meter/MAP sensor signal.

The S-AFC features a user-definable, eight-point, adjustable fuel curve that can be set in 500 RPM increments. The range of fuel adjustment is 50% at each of the user-defined setting points.

On hot-wire vehicles, the Deceleration Air Flow Correction function is capable of curing the erratic idle and stall problems associated with open-atmosphere blow-off valves on hot-wire air-flow meter systems.

Subaru B5-TPH Concept Car

Image
The Subaru B5-TPH is a stylish coupe/wagon/crossover conce pt car that Subaru stresses is not the next Impreza. Its main focus is not the exterior styling so much as Subaru's Turbo Parallel Hybrid (TPH) powertrain, which is linked to the company's trademark symmetrical four-wheel-drive system. That's a shame, since the B5-TPH is the best-looking vehicle to come out of Subaru's studios in some time. TPH places a thin electric motor generator between the car's 2.0-liter Miller-cycle flat-four turbo engine and the automatic transmission. The Miller-cycle technology, which we last saw in the mid-1990s Mazda Millenia near-luxury sedan, improves engine efficiency by reducing pumping losses due to a power stroke that is longer than the compression stroke. Often, this system makes an engine unresponsive at low speeds, but with the electric motor, Subaru claims, standing-start torque is better than ev...

Auto Insurance Glossary

Wondering what all the terminology in your auto insurance policy means? Below is a glossary for your reference. Accidental Death Coverage Accidental death coverage is sometimes a part of your auto insurance policy's Personal Injury Protection or First Party Benefits plans. If someone who's covered dies from accident-related injuries, this type of auto insurance coverage may provide a payment to the insured's designated beneficiary. Actual Cash Value You'll see this term a lot in auto insurance policies or if you ever have to file an auto insurance claim. That's because most auto insurance coverage reimburses you only for the actual cash value of your car. Your car's actual cash value is calculated by determining its original value, minus the amount your car has depreciated since you bought it. Adjuster An adjuster is the person who investigates and settles auto insurance claims. Agent/Broker Agents a...

Maintaining your Turbo Charged Impreza Car Engine

Image
Starting and Stopping your Engine ( including Turbo Timers) When starting the engine, do not press the throttle at the same time! The engine management system is programmed to automatically adjust the settings and if you should press the throttle during the sequence it is actually possible to cause the system to shut down with the result of a non starting car. (A couple of owners have reported a more persistent starting problem. When the dealer connected the "select monitor" to the ECU, a fault in the crank sensor was reported: a new crank sensor cured the starting problems) In order to prolong engine life, a few common sense rules should be followed when starting and stopping the engine of your Impreza. When starting the engine from cold, you should avoid hard acceleration or high revs (i.e. boost conditions on turbo cars) until the engine has fully warmed up. Most engine wear occurs within the first few minutes after starting when the engi...
