A manual ASD install would be possible for someone experienced and knowledgeable but not an easy job. I know in the factory installation it is powered through the OVP (asd cars tend to have a different ovp relay); also there is a switch on the brake pedal which activated and presumably cuts out the ASD operation for some reason.
Have a look a the video I posted on the first page to see it in action. You don't strongly notice it activating. The only time I notice it is if it's wet and I pull away at speed inducing wheelspin. When you hit a certain speed (19mph by the looks of things) the acceleration occuring can reduce - this is I presume due to the ASD cutting out and me being left with less rear lock up and less traction. In the dry, in bends, and making a tight turn while pulling away, I don't notice it operating, so either it's quite subtle, or the existing LSD effect is making a good difference already, or my clutch packs are worn out. Incidentally my ASD diff has slack in it and makes the drivetrain clonky; is it rebuildable and could I do it myself?

In LSD work I've done, I was able to specify how much lockup (what %) I wanted, I've gone up to 60% for some racing applications.
Dave or others might know if the parts are available to create a tighter rear diff for these cars also, I'm guessing yes. Looser also. Quote:

You can add a spring block, which adds pressure to the clutch pack at all times. This basically simulates ASD engagement at all times. You adjust the "percent" lockup by stronger or weaker springs. The only drawback is that you cannot use circlips to hold the axle flanges in place, they will float in & out. The folks who have done this (usualy the 190E-16 crowd) say it works ok though. For street use, I have not found it necessary to do this. I'm sure on the racetrack (road course or autox, not dragstrip!) it's a bigger deal. |

Can it cure looseness in the diff? Cure jerking at low speed and changing gear?

Jerking at low speed and/or when changing gears sounds like a tranny issue, or flex disc problem, and if it is the diff... again, that sounds like a worn-out differential. A tired LSD clutch pack would not cause any of that behavior, it simply wouldn't provide any connection between left & right wheels. |

Change the fluid, be sure you have the correct fluid for LSD.

^^ my opinion also.
LSD doesn't work properly with additives and such, if you don't know what's in there, it's a good place to start IMO.
