I've barely tried using the launch control on my car but today gave it a quick go and was pretty disappointed with it. It bogged down for about a second when first setting off and then eventually got going.

I also then just did a foot flat to the floor start but not launch control and half way through first it just stopped accelerating again for about half a second, then cracked on again. Not exactly the 4 seconds to 60 I was expecting!

Anyone got any ideas or tips if I'm doing something wrong?

First things first. Are your tyres knackered? They may look ok but if they're old they might have lost some grip....

They're Pilot Super Sports, Porsche rated with about 5mm, was pretty warm yesterday and perfectly dry.
The thing is it's not loosing grip and lighting up the rears, it's just cutting the power out.

It cuts the power when it senses grip loss but it'll all happen very quickly without you noticing. I'd eliminate grip issues before I dug any deeper.

If it's safe to do so, knock off traction control and boot it in sport+. You'll light up the rears immediately!

When engaging launch control you're whacking a lot of energy into the rears. Your tyres need to be tip top for effective launch I reckon.

I see your point, but I had PSM off so surely it would just spin the wheels regardless?!

As said, grip shouldn't have been an issue, probably driven 12 miles too so the tyres would have got a bit of heat into them too.
