Exige 410 Retro fitting Vairable slip traction control.

[RaggedRoy]

Has anyone fitted the variable slip traction control dial from a 430 to a 410? 

Turns out there is a spare unlabelled three wire connector behind the steering cowl, I suspect it is a potentiometer input for variable slip.

Do I only need to add the dial? Is the coding already installed? I’m thinking it is possible the system reverts to a generic traction setting if it can’t see the inputs from the dial.

Does anyone have a photo or the details printed on the variable slip potentiometer? The genuine Lotus part is approx £165, I suspect it is approx £5-£10 part.

Thanks
Roy

Does your car have cruise control? If not it could be the spare connector for the cruise stalk.

It already has cruse control fitted. The colours match the wiring schmatic for the TC switch.

Interesting question....did anyone ever find the answer to this?

I think the wire connector you are referring to is for the exhaust valve switch

According to Eddie Cain on Pistonheads the Cup 430 runs different software for that: https://www.pistonheads.com/gassing/topic.asp?h=0&f=15&t=1954585

If you could (against Lotus' wishes) obtain the Cup 430 software then perhaps it is possible. No idea how the dial is connected though; checking the Service Notes I've got doesn't reveal anything (probably an appendix I'm missing). I'm not sure about the claim on different cam timing and hardware changes from that post either; I certainly cannot see anything to that effect on Lotus' parts checker but I could also be wrong there.
