Launch not working


Grazer

Recommended Posts

RLTC installed (amaturelly) and working - thanks to Phil for his spot on dat file.

 

The only problem is the launch control is not doing a thing. I have checked the settings using Graham's app and the RL app, which show the launch settings are programmed.

 

When I hit the button in dry or wet nothing happens.

 

Am I being an idiot and doing something wrong, or is it not working?

 

Answers on a postcard :p

The dat is set to launch at 5000rpm if I remember correctly.

 

This is how RL say you should set it.

 

“The Launch control rev-limits can be programmed using the launch button supplied

as part of the Traction Control Switch. Follow the procedure below to program in Wet

or Dry rev-limits.

• Turn the vehicles ignition OFF.

• Turn the adjuster to wet or dry settings depending upon which rev-limit you wish

to program.

• Turn the vehicles ignition ON and start the vehicle.

• Press the launch button once.

• Press the launch button again and hold down the launch button.

• Rev the engine to the desired Launch rev-limit.

• Release the launch button.

• The rev-limit will be set.”

 

 

Have you checked your clutch switch and the launch control clutch switch settings in the app.

 

EDIT Sorry! forget the last bit, unless you are doing full throttle shifts. As far as I am aware the clutch switch is not required for launches.

 

I just power brake:D

Sorted.

 

Didn't realise you had to floor the accelarator.

 

:stupid:

 

D'oh!

 

Only had a brief play with it - but first impressions are:

 

what's the point?

 

Fair enough, I can't hold the revs at exactly 5000 without concentrating, but you can hold down the accelarator with little enough thought to be able to completely concentrate on the clutch anyway.

 

If that makes sense :p
