has anybody fitted this to their Z? i do quarter mile runs every couple of months and was thinking about fitting launch control, anybody any ideas how much it would cost to do and how i do it? :confused:

There are several ways of doing it. There is The Racelogic system which incooperates Traction control and launch control and will cost you about £600 ish. A group buy also happening at the moment here.

 

There is the aftermarket ECU managment systems like AEM (see Smithy's place in trades section) Omex and Emeral among many others that incooperate both TC and Launch within the management, These tend to be around £1100 to £1200, but have real big tuning advances aswell.

 

Most of the purely launch systems I've seen are coil based controls and limited to I and 2 coil systems so bear that in mind when buying and the Zed is a coil per cylinder.

how does the racelogic system work?

Traction Control Technical

 

Launch Control

 

 

--------------------------------------------------------------------------------

 

Launch control is a function within the Traction Control system designed to automate standing starts to maximise the initial acceleration.

 

It is activated by pressing a button on the dashboard when the car is stationary. This will bring in a secondary rev-limit (for example 4000 rpm).

 

 

The throttle can be fully depressed without over-revving the engine. The car is put into gear, the throttle floored, and then the clutch is engaged, whilst the launch control system controls the wheelspin and revs for the perfect start.

 

On a turbo car, if the launch control is active, and full throttle is given for two to three seconds, the boost pressure will build up before the clutch is released, resulting in stunning off-the-line performance.

 

The launch control rev limit can be programmed via a laptop computer or by a combination of presses on the launch control button. This is done by pressing it once, and then once again but this time holding it in and raising the revs to the desired level, then the button is released, setting the new rev limit to this level. This makes it very easy to re-program the launching revs just before a start if conditions suddenly change.

 

There are various parameters you can tune if you want to get the last little bit of acceleration out of the system. You can have two switchable levels for wet and dry, the level of wheelspin at which the system swaps from Launch Control to traction Control can be adjusted, and on the professional system you can even switch to a lower limit once the car starts to move.

looks like al have to save me pennies then :D

Cracking bit of kit the RL.

 

Launch control is good, and like mentioned you can program two rev limits, only anoying thing with that is that you have to put it on wet, or whatever slip you have assigned to the first setting on the dial. The wet IMHO even when fine tuned is a little too cautious, so could hinder you after a perfect launch.

 

The system runs off of the ABS sensors IIRC, then the system detects wheel movement lauch control toggles off.

 

It's a shame that there aren't any rev limiters for mulltiple coil systems. I've been searching high and low and can't find anything other than this Bee r thing that I'm trying to find out more about.

 

Essentially if you have a rev limiter, you could do two things, activate it on a switch to the clutch so you would have FTS, and you could also rig it to a button on the S/wheel effectively giving you a basic launch control at the same time.

 

But as mentioned, I'm not sure a suitable rev limiter is on the market.

They run about $350 usd with the shift light.

and the z1 guys are kind and post the item as a gift keeping uk parasites from bumping the price up... right? ;)

Hmm, I heard the Gizzmo thingy is harsh on coil packs. Still searching for a decent limiter grrrrrrrr
