Hi ive just bought my second VX220 and its come with RACELOGIC Adjustable traction control, i havnt a clue how to use this i dont know what it exactly achieves or how to set it up though i think it is already, what does the percent thing mean etc, ive tried searching threads but still not clear? Any help appreciated??? Regards

The percentage allows you to determine how much slip is allowed before the traction control kicks in. I believe this is done by comparing the rear wheel speeds to the front wheel speeds (with some clever jiggery-pokery to cope with cornering). So 0% doesn't let the rear wheels spin any faster than the fronts, 10% allows them to spin 10% faster, and so on. Zero percent will be 'safest', and most like normal traction control, but will stop you from making fast starts or getting any oversteer at all. The more slip you allow, the more fun you can have, but also the more potential for disaster! If you don't have any details for the device I'd try phoning up Racelogic and seeing if they can e-mail/post you the instruction manuals for your controller.

PDF manual from here:

And lots of info on the site:

You can use the software to tweak the settings once you've got the hang of using it. I've not got it on the VX but fitted it to a Civic Type R and it's a great bit of kit.

anyone fingered out the launch control? I've just got a scary red botton. And the manual doesn't make much sense.

It's a good way to go through engine mounts on a VX, I'd bet!

As I understand it, you set the rev limit of the launch control through trial and error, following the instructions in the manual. You want to get a rev limit that lets you set off without bogging down, whilst not spinning the tyres so much that you just create a cloud of smoke.

Then you can just push the button to enable the launch control, floor the accelerator (it will limit at your pre-defined level), and then smoothly let out the clutch - perfectly repeatable starts every time. Once the car gets up to a certain speed, the launch control automatically disables and the TC unit goes back to the previous slip setting.

Set it for 0% slip in the wet and this time of year when tyres don't warm or on salty roads etc.
When dry and warmer set for 10% slip.
If it cuts in, you're first instinct will be to wonder why the engine is 'missing' as it cuts the spark. The spark cut is progressive according to how much you're out of shape.

Read the PDF manual and experiment with the variety of settings available.

I've never used the launch control, bit of a gimmick really. Good way to lunch your clutch and engine mounts I think.

ok great thanks for info my engine when i turn it on is not settling very well the rev counter bounces only a tad continuously on idle. hopefully setting this to 0% will reduce this idle wild? Regards

Can't see that rough idling will be anything to do with the traction control. The traction control simply monitors the ABS pick up on each wheel when the car is moving and if they go out of synch (loss of traction etc) it cuts power.
Rough idling will be some sort of engine managment issue I would think, and will require a diagnostic check to pinpoint.

ive used the launch control to test it. mines set to give me 15% more slip on launch control
and i set therev limit to 3000rpm

activate launch control, foot to floor, get clutch near biting point then release it, keep foot to floor and after a certain speed it turns back to normal traction control.

works VERY well IMO!!

i had my TC set to 1% testing on an empty ind estate and could foot to floor it from a T junction and it just kept in control all the time.


thats in the cold on r888's when it was damp.

Hi ive just bought my second VX220 and its come with RACELOGIC Adjustable traction control,

Is that minime's car?

[dw1]

All VXs come with traction control, it's called the right foot. I can see why if a car is a Stage 4 it might be useful. I'm interested does the TC dull the driving experience of the car? On all the driving shows and car magazines they seem to disable the TC as soon as they can.

That's because they're on a track and want to show off

Seriously, though, you only have to look on this forum in the winter months to see how many people are writing them off - any I'd say probably 50% of those are caused by excessive throttle application mid-bend. If those cars had TC fitted and activated, there's a good chance that at least some of those crashes could have been avoided.

Of course TC dulls the driving experience - if you're on a nice track with lots of runoff. And of course if you're a perfect driver then you shouldn't ever need traction control. But in the real world, with variable road conditions and drivers who only think they're perfect, I can see the appeal.

The "WET" setting is zero slip and you will probably feel it cutting in in the dry when accelerating hard in a similar way to many factory traction control systems work (feels annoying as the car feels held back). Sometimes wheelspin isn't detectable under hard acceleration but there is slight wheel slip so in the dry the best setting is..."DRY" as this allows for this slight slip for unheeded acceleration (no rear breakaway though) but you won't notice it cutting in in most cases. Use the percentage ratings for slip which will allow sideways movement, though even 20% isn't a mega amount (not compared to completely off anyway!).

I used my TC to such good effect at Spa Francorchamps the ECU cut an injector because I was hard cutting the TC so much, because I found that I could hammer the throttle at the apex of the corner much earlier and in true pre 08' F1 style let the electronics sort it out. When I tried driving without the TC I had a few scares keeping the VXT at the same pace. The TC keeps the car going in the right direction and over a lap of Spa I reckon its worth 2 secs per lap when looking at lap times. For tracks its useful with tight hairpins and where there's hard acceleration out of a corner. Cheers Ian
