I'll chip in my two pence worth.
After getting the traction control light only light on maybe once or twice per year since owning the car on a recent tour of lake district it was happening every journey, so after a quick google I thought the first place to start was changing the brake pedal sensor (I ordered from monkey wrench racing in US and cost nearly £30.... I think its possible to find a lot cheaper at a local motor factor https://www.monkeywrenchracing.com/product/grp-brake-pedal-switch-evora/).
At first it didn't seem to have worked but after a quick text to a friendly lotus master tech he said the way he recommends to install rather than setting 'clicks' is to just pull plunger all the way out, push the brake pedal in and fit and then let brake pedal push switch in and set number of clicks (will make sense when it in front of you).. bobs your uncle all fine now after a month or so.
As an aside (and to get back on thread) and i'm not 100% its not a placebo I do feel its become a lot more consistent when blipping the throttle for heal and toe, which I did used to find inconsistent.
so for a relatively cheap potential fix if you suffer from heal and toe inconsistency, maybe try changing brake pedal switch.
