Cool! Sorry for the delay, I've been flat out over the last 3 weeks or so - I did my first race in my car, plus then the financial year end and a quarterly business owners' conference I go to, it was a bit of a perfect storm.
The way I was testing was basically making sure that it doesn't come on in a straight line under hard acceleration if you don't have wheelspin. In fact I'd log it and see what slip values you see in the log.
I'd do some hard cornering with power down (but not sliding out) and then logging the slip you get in those conditions as well.
I'd then start logging what slip values you get when it starts to slide, and also spin in a straight line (I'm not sure if your MX5 is modified enough to do that or which gears it would do it in).
Then enable the traction control, set the allowable slip error and target slip so that the sum is some value between the two (ie the value when it starts to slide / spin and the values you get under normal conditions). I'd use P only gain initially and start with a value around 50 - try more and try less so that it's not too harsh when it comes on, depending on what you want it to do (eg, just alert the driver, or do you want it to be really severe like a production car).
