Default General ELC Question

Hey guys.
In all the reading I have done on the ELC system, one thing I do not have clear yet. When exactly should the ELC start working? If the car is unloaded, with a full tank of gas, lets say, should it be supported only by the springs, or should the ELC be contributing also? In other words, does the ELC only start really working once the car is loaded to a certain extant, or is it an integral part of the suspension even without a load in the vehicle?
Thanks!

It will always start working when the car is started, even if its been sitting for only 5 minutes. It will turn off and on intermittently to keep the car level. Or if you are carring 900lbs of cement bags in the trunk it will not go off at all.

We need to know which car you're asking about.

The system changed in 1996. Previous to that, the ELC is active even when the ignition is off. After that, it only comes on after the ignition is turned on.

In the future, when you post a question, please clearly identify which car you're talking about. Both of your cars should have ELC active at all times (assuming they both have ELC).

Actually, it was just a general question on ELC. Was not really concerned when it shifted on or off, but rather how it affects the spring rate and height.
From what I understand from the above, the springs are not strong enough on their own to maintain ride height without help from the ELC.
The car I am working with is my 95...

correct, springs alone won't hold the rear end level

FE2 suspension in the C and H bodies was specifically calculated for spring rate and loading based on the ELC system being there and active.

How about FE3?
FE1 is so damn soft that the ELC NEEDS to be there!

No, it'* spring RATE the ELC is there for in FE2. They knew they wanted it for LEVELING, so they calcualted it in for HANDLING.

You have FE2, not FE3.
