A feature known as drive-by-wire, or electronic throttle control, became standard on Gen IV motors after previously being available on a limited number of Gen III types only. It wasn’t until 2005 that the first Gen IV engine, the LS2, appeared on the scene, and once again it was employed in the Corvette as the company’s flagship vehicle.
The throttle body with a drive-by-cable system on the left is typical of the early Gen III LS engines in general. Some of the later Gen IIIs, such as the one seen on the right, were equipped with drive-by-wire systems.

Do you need a fuse box for LS wiring harnesses?
Some LS wiring harnesses incorporate the fuse box located beneath the hood. This should be bolted down at a handy area. If you’re using an aftermarket harness that doesn’t have a fuse box, check sure the power cables are correctly fused before proceeding. The image is courtesy of Street & Performance. A grommet is necessary whenever wire is passed through the body of the vehicle.
What are the different types of fuel injectors for LS engines?
You may choose between three types: the old-style STD injector (which is distinguished by a huge metal bale clip), the T-style injector (which is distinguished by the use of a Delphi 45 plug), and the Flex Fuel injector (which is also known as the Z-style). Because LS engines are plug-and-play, installing the harness is a straightforward process.
What kind of engine does a Ford LM4 have?
The heads were either 862 or 706 casts, depending on who you ask. Displacement on demand, active fuel management, or variable valve timing were not available on any of the 4.8L LM4 engines. Because it reacts well to boost and power adders, the 4.8L engine is commonly referred to as the ″ 4.Great″ engine or ″4.Great″ engine.
Is a drive by wire engine a deal breaker?
- However, my Silverado has drive by wire, so you cannot manually open the throttle body to rev the engine while under the hood.
- This is not a deal breaker, but it is a minor inconvenience (to the best of my knowledge).
- That might be a nuisance during tuning.
- I’m aware that on some cars, what is on drive by wire isn’t always what the ecu wants it to be, and that the ecu may cut it back at any time.
What year LS are drive-by-wire?
LS Tech as well as moderator. From 1999 until 2006, drive by cable (DBC) was in use. By 2003, DBW trucks accounted for the vast majority of the fleet.
What year 5.3 has drive-by-wire?
What years did the Chevrolet Silverado 5.3 have drive-by-cable? They either switched from DBC to DBW during the year 2003, or they did so in the midst of the calendar year 2003.
Is LS3 drive-by-wire?
OEM GM LS3 electronic throttle body with four bolts, 90mm in diameter, for use with TBSS/NNBS or L92 intake systems. Applications requiring drive-by-wire will require the installation of a Torque Rush Performance X-Link wiring adaptor from 1999 to 2007. (sold separately).
Is LS2 drive-by-wire?
A drive-by-wire throttle body is installed on the LS2 engines; hence a drive-by-wire throttle pedal will be required for the LS V8 engine conversion to work properly.
How can you tell the difference between a 5.3 and 6.0 Vortec?
Gen 3 engines with an iron block and truck intake manifold, and the number 6.0 stamped on the block, are classified as LQ4 or LQ9 6.0L engines, respectively. The engine in question is a 5.3L LM4 or L33, which is a Gen 3 aluminum block and truck manifold combination.
When did GM go to throttle by wire?
With the introduction of the LS1 engine in the 1997 Corvette, General Motors pioneered electronic throttle, sometimes known as drive-by-wire.
What year was 4.8 drive by cable?
Engines with return-style fuel systems were used on the early LR4 4.8L engines (1999-2003), which were all driven by cable. Except for the Van versions, which continued to use the return style, drive by cable system until 2007, all of the vehicles were converted to drive by wire with a returnless fuel system starting in 2004.
What is a TAC module?
A throttle actuator (TAC) module is a type of electronic throttle actuator (this is the computer that controls the throttle body)
How do I identify a Vortec engine?
Examining the cylinder heads of the 5.7L Vortec engine is a quick and straightforward technique to identify the engine. The cylinder head for the GM Industrial Vortec engine was created by inserting LT1 Corvette ports into an iron casting. The intake manifold mounts to the head using an 8-bolt design, as opposed to the majority of other 5.7 GM heads, which use a 12-bolt configuration.
Is drive-by-wire better?
Increased precision in throttle control is achieved by the use of data from a throttle position sensor and input from a potentiometer attached to the accelerator pedal, both of which are controlled by the electronic control unit (ECU). Drive-by-wire technology eliminates the need for any mechanical connections, allowing for weight reductions to be realized.
Is ride-by-wire better?
The following are the advantages of using a ride-by-wire throttle: One of its advantages is the ability to have exact control over the air/fuel mixture. Another is the ability to combine cruise control and multiple riding modes, which allows for varying throttle response.
Is the LS2 drive-by-wire throttle body?
When it was released as the basic engine for the 2005 C6, it had a new four-bolt design with an increased 90mm silver blade and a new four-bolt design with a bigger 90mm silver blade. The electronics for these LS2 throttle bodies were integrated within the throttle bodies themselves, using a single six-wire connector to connect them together.
What is throttle body drive-by-wire?
Drive by wire is a method that eliminates the need for traditional physical connections in favor of a wire that transmits an electrical signal. For example, in gasoline engines, the throttle wire is often routed from the gas pedal to the butterfly in the throttle body, which regulates the quantity of air that enters the engine and limits the amount of power produced.
How do you reset a throttle body drive-by-wire?
Check to see that the accelerator pedal has been fully depressed. Turn the ignition switch to the ″ON″ position and hold it there for at least 2 seconds. Turn the ignition switch to the ″OFF″ position and wait at least 10 seconds. Turn the ignition switch to the ″ON″ position and hold it there for at least 2 seconds.
