EEC-III on carbureted cars controlled the same Ford 7200 VV carburetor as the EEC-II. On fuel-injected cars, the module fired two high pressure (approximately 40 psi) fuel injectors that were mounted in a throttle body attached to a traditional intake manifold in the center valley of the 5.0 liter (302 cid) engine.
Vintage engine testing equipment that can test ignition timing, ignition dwell, manifold vacuum and exhaust emissions. Engine tuning is the adjustment or modification of the internal combustion engine or Engine Control Unit (ECU) to yield optimal performance and increase the engine's power output, economy, or durability.
The term fuel injection is vague and comprises various distinct systems with fundamentally different functional principles. The only thing all fuel injection systems have in common is the absence of carburetion. There are two main functional principles of mixture formation systems for internal combustion engines: internal and external.
Common rail fuel system on a Volvo truck engine. In 1916 Vickers pioneered the use of mechanical common rail systems in G-class submarine engines. For every 90° of rotation, four plunger pumps allowed a constant injection pressure of 3,000 pounds per square inch (210 bar; 21 MPa), with fuel delivery to individual cylinders being shut off by valves in the injector lines.

In this way, precise fuel injection metering is still retained at all engine speeds and loads. Australian tuners in comparison, prefer to use the less precise method of MAFless tuning (see 'Disadvantages' section above), requiring the engine computer to use predetermined fueling tables, resulting in less finely tuned injection systems that ...
Central Fuel Injection became available in 1984, raising output to 120 hp (89 kW) at 3600 rpm and 205 lb⋅ft (278 N⋅m) of torque at 1600 rpm in models so equipped. Multi-point fuel injection (single port) became standard on the 3.8 L V6 in 1988, raising power and torque to 140 hp (104 kW) at 3800 rpm and 215 lb⋅ft (292 N⋅m) of torque at ...
