Default Launch control vs f*cked clutch?

Had LC installed a few weeks ago & used it in anger last night just to test it out. Took off like a scalded cat which is albeit with quite a nasty burning smell too Is that normal & can I do anything to avoid it?

Cheers, TX.

I take it you're getting little or no wheelspin so to adjust tyre pressure up abit to transfer some power out onto the track.

Thanks Shaun

TX

PS

It's on a switch so intended just for Quarter Miles etc.

Edit - yeah no wheelspin, just took off.

What clutch are you using?

How much power and torque?

^^ Exedy API clutch. 398hp at last RR albeit was 1.4bar boost (peaked at 1.5 then dropped back to 1.4) whereas 1.8bar at moment (peaks at 1.9 then drops back to 1.8) - guess perhaps 430-450hp now? Torque was 380 ish back then too.

The clutch on my own car STi JDM blobeye has been launched god knows how many times. I'm now at 30,000 miles on the original clutch and it still stinks from time to time It seems to be a feature of 6 speed clutches.

I think mine [ 395 hp / 394 ft lbs ] is beginning to get tatty as the pedal is high BUT it still grips and doesn't slip or judder.

The car is for sale and l'll put a new one in before it goes.

How aggressive is the LC setting though? I understood from an earlier post it was similar to mine. 0.8 bar/5600rpm- I have 400lbs torque and get a bit to much wheelspin, Pod track or road, my API sixspeed clutch doesn't blink at this.

You ideally want it to break traction (lighting up the wheels) unless you fancy the potential of breaking a part of your transmission.

^^ Is that down to tyre pressure as noted by Trevs above?

All depends on how you are what you are using it for.

If it's on the strip you want as much traction as possible (which is a fine art in balancing against it bogging down), so you would perhaps lower pressure and use the grippiest tyres you could. Not very transmission friendly though.

If you are using it on the road just for a laugh, I would suggest you don't want to over inflate your tyres to get it to break traction easier (transmission friendly).

Launch Control can be a pain in the backside as it may need to be set-up for each type of surface and tyre combination to get the best from it. It's a balancing act between too much spin and it bogging down.
