launch with full lock, then open once into 2nd

thanks for that, will it harm it to leave the lock on through the quarter mile then ?

wont harm it, just offers greater drivetrain resistance, thus slightly slower (in theory)

Isn't it possible to have it operating at fully lock by just pressing a button conveniently located on the steering wheel with your left thumb and then releasing as soon as you get to shift gear. Thus running the 1/4 in regular mode and launching locked??

After all, the sophistication [ if that's the word ] of it, is not necessarey for that purpose. It just needs a live and return to lock it up.

Seen that set-up on several cars on hillclimbs, esp Audi quattro

David, yes, thats effectively what my motec does for me, except the opposite way. ie set it fully locked, and once above a certain speed, set to fully open.

Thanks everybody, David if you could devise such system i would be very interested in having it fitted

It's quite simple Steve, Just a bell push button and 2 wires to the dccd. In a position that you can hold it down with your left thumb then when you go to grab 2nd gear the button is released and so is the Dccd.

Unless you expect to get wheelspin in 2nd also, in which case right thumb......

We'll do it for you if you wish - whenever you get running again

Or use the handbrake switch

Much like David has already said but you dont need to go near the dccd. If you put the handbrake on the dccd will revert to fully open regardless of where it was set. If i remember rightly when you lift the handbrake the switch makes and connects the wire to ground. All you would need to do is add a normally closed switch in parallel with the original handbrake switch so that when the button is pressed it's like the handbrake being off, once your into 2nd or at whatever point you choose let go of the button and the dccd will go fully open.
Sure Andy.F used to do something similar a few years ago on his car when he ran a dccd, there's a video clip somewhere when he lets go of the button too early and smokes the rear tires!!
