I had it on my phase 1, it imposes a rev limiter just above 4k when your at a standstill so you just floor the accelerator and pop the clutch, the rev limit is fixed up till about 15-20mph (i think) so you don't wheelspin to much.what does launch control actually do / consist of for a clio?
You could just get a omex limiter, second hand don't cost too much then wire it in to the coil wiring
I plan on fitting one of these, they don't half create some loud bangs on the limiter!
