Well, I learned really a lot from this tread.
I think we can conclude Autoxers' want and need a LSD but those of us who are interested in tracking our car we are better of tuning our suspensions
(And lift the front inside wheel )
Since I am a newbie to all this how about picking Simon's brain on how to setup an Elise for track days.
So Simon would you mind sharing you experience and setup here:

So I am guessing there is no way around installing the TC if you put the LSD in it. Anyone know the cost associated with it?

The way around installing the traction control when installing LSD is to buy the LSD from toyota, as per fzust's suggestion, and not install the TC.

This doesn't work if you're running SCCA SS class, or if you're concerned about spinning in the rain, but works fine otherwise.

Oh, the TC parts from lotus are about $135 in the US or $95 in the UK, not including the software.

If you're installing T/C yourself, could you use a different type of switch? Instead of a button that you have to push every time, could use a toggle that stayed off, or stayed on?

i haven't checked the wiring of the switch, but i overhead nick adams mentioning that the TC software looks for the switch, and if it doesn't find it, disables the TC.

Two questions, if you guys happen to know:
1.) Is this TC kit a complete retrofit kit, including installation instructions? My dealer says it doesn't exist, but I don't know how hard he looked.
2.) Do the dealers have access to the ECU re-flash for TC-equipped cars?

At $125/hr, I'm more than happy to give up the warranty on my tranny by having a high-quality drivetrain shop I know that charges a lot less install the Toyota LSD and have the dealer do the TC, so they'll perform the ECU re-flash.

I think the main problem with the dealer is that he's been told by Lotus USA that they're "working on it" but haven't decided how to handle the whole LSD/TC retrofit thing. So he's very reluctant to do anything that might preempt their decision, like do a TC-only retrofit.

The latest murmurs have it that the dealers will not have access to reflash ECU code and TC ECUs will be on an exchange basis only.

I run SS and would ike to have the LSD. It would be nice if they offered the LSD without the TC so we could just throw one in!

This is the exact same part as the Lotus part they want ~$1700 for?

Anyone have any more info on the harness? How hard is it to hook up? Aside from the switch, where exactly does the other end go, and how does it pass through the firewall? Is it something you need a shop to do, or is it an easy install? Thanks for an update...

Harness info.

You need to remove the console, the (LCH) "labial cup holder", the rear wall behind the seats. You may need to remove seats to make that easier. :-/

You need to drill a certain size hole in the console using a supplied template. Insert switch with short harness around 12" long with connector on the end.

Plugs into main TC harness which includes two stripped and tinned wires for connecting the existing harness inside the console.

You drill a hole using the directions and one large-ass drill through the firewall behind the LCH. Insert the new harness with its grommet (pre-assembled) into the hole.

Insert two connector pins from the harness into the ECU connector.

Reflash ECU. Test.

Thanks Randy!

Can't wait for the test part, that should be fun. "honestly officer, I had to smoke the tires to see if TC was on or off!"

Every day I like what I did better and better.

Now if we can just dial the suspension in with the LSD...
