How big are the fuel injectors on a corvette?
For your reference, use the above instructions to calculate fuel injectors size for your Corvette based on target peak horsepower. Instructions courtesy of Precision-Flow. 1993-1995 ZR-1: 20.5 lb/hr both injectors at 43.5 psi (designed for ethanol)
When was sequential fuel injection introduced in corvette?
It was reintroduced in 1994 along with sequential fuel injection. The 1985-1989 mass-air system had a few changes along the way. 1985 cars have a slower baud rate computer and use a mass-air sensor module to control burn-off and to power the mass-air sensor.
What was the first fuel control system for corvettes?
Speed density was the first fuel control system used on 1982-1984 Corvettes. It was also used on the 1990-1993 cars. Speed density uses a manifold absolute pressure sensor (MAP sensor) to calculate the necessary fuel load.
What was the first C4 fuel injection system?
C4 Fuel Injection Overview. Speed density was the first fuel control system used on 1982-1984 Corvettes. It was also used on the 1990-1993 cars. Speed density uses a manifold absolute pressure sensor (MAP sensor) to calculate the necessary fuel load. The 1990-1991 cars have a MAP sensor bolted directly to the intake plenum.
How does a C4 Corvette engine start up?
(The L98 injectors all fire on one side of the engine at the same time followed by all injectors on the other side firing at the same time. The LT-1 fires the injectors individually per the firing order). Brainiac Fact for C4 Corvette Start Sequence!
What should the fuel pressure be on a C4 Corvette?
C4 Corvette Start Sequence begins when you first turn the key to the “on” position, the fuel pump will run for 2 seconds pressurizing the fuel rails. There is a Schrader valve on the passenger side fuel rail near the rear of the engine and proper fuel pressure after the pump runs should be between 40-42 pounds of pressure.
Where is the oil pressure switch on a corvette?
Note that you should have a black color oil pressure switch/sender. This sender is mounted behind the distributor on the driver’s side. If its not replace it with one that’s only black. If the car fires then stalls replace this switch.
What should the idle speed be on a corvette?
Initial engine idle speed of should be around 900-1100 RPM and then slowly decay to around 600-700 RPM unless the air conditioner is on at which case it will run at around 800-1000 RPM depending on pressure altitude. If this does not happen, the Idle Air Mixture Valve or IAC may be plugged or faulty.
