5.7 Liter LS1, LS6 V8
6.0 Liter LS2 V8
6.2 Liter LS3 V8
7.0 Liter LS7 V8

The ZR1, Z06, Z51 are pertaining to performance pakage ie suspension etc.

The C4, C5, C5 etc is referring to the generation.

I apologize if you didn't receive all of the information you were looking for. I thought that link I provided covered it all. What information are you still looking for. I will do my best to help. Again, sorry for any misunderstanding.
Customer: replied 2 years ago.

Dear Mr. Diag,

 

1. Would you explain what "Active Handling" is? How does it work?

 

2. Also, there are three modes of driving which are selected by a switch on the console. Would you please explain what these modes do and how they act? The owners manual does not do a good job of explaining. Also, last explanation from your colleague was not detailed enough.

 

3. Last question: Do you know of a good reference book which explains the workings of the 2008 Corvette. I do not think a shop manual is basic enough for me. The web site you referred me to was basically an excerpt from the Corvette Black Book which I have and read. It is ok but not very detailed. Also, It does not explain all of the acronyms which Covette uses (see previous questions).

Hi Tony,
I will do my best to try and shed some more light on the things that you have mentioned. My goal is to help you with your questions, and provide you with quality service. Unfortunately some information can be very difficult to obtain. I have looked and so far I have not been able to find any sort of good reference book that will tell you what you would like to know about your car, with any more detail than the owner’s manual. I would think that this type of info would be readily available for those of us that are Corvette enthusiasts, but am starting to wonder where it could be hiding. I will continue to look and let you know if I can find anything.

In the mean time, I can provide you with some info that might help. First, I will include a list of option codes, also known as RPO codes, for the C6 vettes. These codes are usually 3 characters and indicate options that were available for the vehicle. Most GM cars and trucks have an option label (sometimes on inside of glove compartment or in trunk) that lists the options the vehicle was built with. For instance, ZR1 is an actual option code for “Performance Package Special Coupe” on the Corvettes. The LS6, LS1, etc. are option codes for the engine. The C1-C6 which is not the same as an option code but is the generation of the Corvette. You will find a rather lengthy list of option codes at the end of this post.

Now, I will try to explain active handling. Active handling is designed to detect and correct unwanted vehicle maneuvers. Inputs to the control computer are provided by sensors which calculate steering angle, yaw rate, and lateral acceleration. (Yaw is the vehicle’s propensity to rotate about its center. Lateral acceleration is calculated by determining the amount of centrifugal force created in a turn.) The system also ties in with the ABS sensors, traction control sensors, and the hydraulic brake circuits. This system has the ability to grab hold of a poorly executed maneuver and help correct or reduce too much understeer (when the front tires are turned but the car is not turning as much as intended due to loss of traction in front tires to some degree,) or oversteer (when the car is turning more than intended due to loss of traction in the rear tires to some degree.) The Corvette’s system is much different than the older stability control systems which could react too quickly and take away the feel of performance and handling. The Corvette’s system still lets you have that sporty feel and have more input on what the car actually does. The system goes into action only when the car’s limits have been exceeded. The system activates when it determines there is a significant difference between what the driver is attempting to make the car do in a corner and what the car is actually doing in the corner.

Since some corvettes are driven on a race track occasionally, there is a competitive driving mode that deactivates the traction control system. Although the stability system’s sensors and wheel braking hydraulics are still armed and in the game, it still allows moderate wheel spin for added acceleration and cornering corrections (oversteer) without backing off the throttle, changing ignition timing, or applying brakes to spinning rear wheels.

I hope this information helps. Let me know what you think.

Customer: replied 2 years ago.
MrDiag,
I am currently planning on taking my Corvette to the drag strip. As you
know, it is an LS3 with a paddle shifter.

What is the procedure for efficient drag racing with this car? I have heard
several stories and they are all different i.e. use paddle shift, start in
second gear, don't do starting line burn-outs, don't use paddle shifter,
power brake to 2000rpm before launching, etc..

Also, I am still looking for a good technical text book, journal or
whatever to assist me with better understanding my vette. Any suggestions?

Thanks in advance,

tony
