Could swap boxes?

however im sure ive heard you can add launch to a none lauch with a bit of wiring?

But the guy would have originally said "wanna swap", not "wanna split".

 

Not sure on that, I would have thought that the very minimum between a rltc + lc & rltc - lc would be a physical switch, and any internal upgrade would be purely a software/firmware upgrade in the unit

Heres what i copied from a post on here some time ago:

 

On the back of the adjuster there are two soldered holes that are not used (IIRC) you just need to get a button and solder it to these holes.

Other than the settings in the software thats it. When i get it off the car at the weekend i will get some pics.

how does the launch control work on these? any good for a bpu auto at the strip?

 

In a word, NO. The launch control relies on the clutch switch to work. With an auto it never knows when to stop doing the launch and just doesnt work.

 

The idea is that you turn on launch control, floor the accelerator and keep the clutch down, then either slam the clatch up and let the drivetrain take the abuse or slip the clutch just the right amount to get a proper launch. Seen it in action and not sure of the benefits, but with practice I'm sure it would help.

so what does the launch control actualy do then.

 

Holds the revs at a pre-set level, eg 4000rpm and you keep your foot jammed on the floor. Then when you launch it is set for the best slip level to cope with the launch. You want something like 10% slip for the best launch or something.

I think combined with a decent clutch it could be outstanding, but a few full throttle launches with it turned on would take out an aged stock clutch pretty quickly.

 

I'm still a massive fan of RLTC and was going to buy this one a while back but forgot all about it!!
