Turbosmart Pneumatic Fuel Cut Defender

Turbosmart Pneumatic Fuel Cut Defender

The pneumatic fuel cut defender from Turbosmart is suitable for most cars using a MAP sensor. Most later model cars have built in defence mechanisms to guard against increases in boost pressure, such systems are important but can be an obstacle when increasing boost pressure.A Turbosmart fuel cut defender will allow boost pressure to be increased above the factory level and will prevent momentary shutdown of the fuel injection system when boost increases. This allows for an accurate and simplistic increase in the factory fuel cut out level without the need for cutting wires or affecting off boost conditions and can be locked out to prevent tampering. The unit itself is subtle and compact, constructed from a durable and lightweight billet alloy, ideal to be shown off or tucked away – whatever your requirements.The pneumatic fuel cut defender comes supplied complete with fitting kit and is to be used in conjunction with a Turbosmart boost controller.View more

Turbosmart Electronic Fuel Cut Defender

Turbosmart Electronic Fuel Cut Defender

The electronic fuel cut defender from Turbosmart alters the output of a factory air flow meter by a simple adjuster to accurately raise the factory fuel cut point without damaging the engine.Most late model cars have built in defence mechanisms to guard against increases in boost pressure which can signal problems on standard cars. Such systems are important but can be an obstacle for tuners when increasing boost pressure. A Turbosmart fuel cut defender will allow boost pressure to be increased above the factory level and prevent momentary shutdown of the fuel injection system. Constructed from a high quality billet alloy for durability, the Fuel Cut Defenders simple design makes adjusting simpler and is still small and light enough to be tucked away for a 'sleeper' look.This fuel cut defender features LED indicators for easy set up and adjustable release ensures you retain the safety of having a fuel cut to protect your engine from over boosting. The adjustment feature enables the sensor signal to be clamped flat or at another gradient to suit your application, the fuel cut defender is to be used in conjunction with a Turbosmart Boost controller.View more

OMEX Shift Light Sequential

OMEX Shift Light Sequential

The shift light sequential from Omex is based on the systems used in Formula 1 and BTCC. The shift light sequential features four high power colour LEDs in an external module which light incrementally as you approach the shift point. These LEDs can be programmed to light at intervals of between 0 and 600 RPM per LED from the shift point. The shift point can be set from 2,000 RPM to 20,000 RPM on 2 cylinder, 4 cylinder and distributor-less ignition systems, 12,000 RPM on 6 cylinder and 10,000 RPM on 8 cylinder.  All Omex microprocessor based shift lights and rev limiters feature Omex's acclaimed method of calibration.

Ignition System

The ignition system of an internal combustion engine is an essential part of the overall engine system. It generates a spark or a very high voltage to ignite a fuel-air mixture in the engine’s combustion chamber. The system also controls the timing of the spark/voltage to ensure it occurs at the right time and is sent to the correct cylinder.

These systems are made of two circuits which work together to create an electric spark at the spark plugs. These circuits are:

  • The primary circuit - this circuit operates on low voltage (12 to 14.5 volts) and is responsible for producing a signal to fire the spark plug and sending the signal to the ignition coil. The ignition coil converts this 12/14.5-volt signal into a high volt charge.
  • The secondary circuit – this is the high voltage section of the ignition circuit. Once the voltage is stepped up, it goes through this circuit and is then directed it to the correct spark plug at the right time.
  • The Basic Components of an Automotive Ignition

    The ignition circuits are made of various components designed to achieve specific functions on the system. These components are:

    Battery – the battery provides electric power for the circuit.

    Ignition switch – this component is normally mounted on the dashboard or steering column. It controls the current flowing through the battery and the ignition.

    The ignition coil - the coil features a metal casing containing two sets of wires on a central iron core. This electromagnetic device converts battery voltage into high-tension current (30,000 volts and greater).

    The distributor – this unit directs the flow of high-voltage current from the coil and sends it to each spark plug. It has a metal bowl that contains a central shaft which is often driven by the camshaft. The bowl houses the capacitor, distributor cap, contact-breaker points, and rotator arm.

    Spark plugs – these devices provide an air gap in the combustion chamber for an electric arc. The high-tension current from the distributor flows through the spark plug then generates a spark as it passes through the air gap to the side electrode. The spark then flows through the spark plug body and the engine, then back to the coil, completing the circuit.

    Types of Automotive Ignition Systems

    Automotive ignitions have evolved over the years to deliver improved and more powerful performance. Today, there are three main types of automotive ignitions and despite their differences in components and technology, they operate on the same basic principle.

    Here’s an overview of the three types of systems:

    1. The breaker-point ignition

    In this type of ignition, the distributor cam and shaft rotate when the ignition switch is turned on causing the distributor cam to close and open the contact points. Since contact points of this ignition are connected to the primary windings, they make and break the primary circuit. When the contact breakers are closed, the current produces a magnetic field in the coil’s core. When the points open, the current stops flowing causing the magnetic fields generated in the coil to collapse. The change of magnetic flux produces a high voltage in the secondary windings that causes the gap in the spark plug to arc and ignite the fuel.

    The biggest drawback of breaker-point systems is that they require regular maintenance to compensate for wear and tear.

    2. Electronic ignition

    The main difference between the breaker-point ignition and the electronic ignition is in the primary circuit. The primary circuit in a breaker-point system is open and closed by contact breakers while that of the electronic ignition is open and closed by an electronic ignition control module.

    This type of system is maintenance-free as it doesn’t have moving parts, has more power output and is more fuel efficient. Types of the electronic ignition include capacitance discharge ignition (CDI), piezo-electric ignition, the Texaco system, and transistorized system.

    3. Distributorless/Direct system

    This type of system is common in modern engines. It doesn’t have a distributor but instead has an ignition coil mounted on top of the spark plug. The timing of the spark plug is controlled directly by the engine control computer or by an ignition module.

    The major components of the distributorless system are an electronic control module, a magnetic sensor, coil packs, and a crankshaft reluctor ring.

    How an Ignition System Can Improve A Car

    These systems degrade with age and mileage, resulting in inconsistent spark delivery or misfires. Ignition problems can also cause a rough idle, loss in power and acceleration, reduced fuel economy and even stalling.

    Upgrading the system with high-quality components will deliver a more powerful spark, resulting in increased engine efficiency and performance.
