hiya guys, im just wondering what could i do to prevent wheelspin, Apart from suspention, tyres and wheels. had a race with an m3 csl yeaturday, he used launch control and left me for dead to 60, then i started catchin up in 3rd still behind him by 90mph tho and catching up fast very very fast.

a few grand on a stand alone ECU with traction control - or a boost controller that will limit the boost in lower gears. Or control it with your right foot!

I would say adjusting the boost controller too/different controller or not giving it quite so much in the lower gears, not easy though when your trying to have a burn up.

how about you just don't race on public roads?

You can try the Racelogic Traction Control. No Motec etc needed. I think Whittler has one.

I think he generally wants to limit wheelspin...be it on a track or on the road...

could do, but still

you shouldn't race on public roads <img src="/forum/images/graemlins/smile.gif" alt="" />

I think we all know that already Craig! <img src="/forum/images/graemlins/wink.gif" alt="" /> <img src="/forum/images/graemlins/tongue.gif" alt="" />

Doesn't say anywhere it was a public road. <img src="/forum/images/graemlins/wink.gif" alt="" />

thats also true

but i don't think you can go to a track and have a race with just an M3

if he was on th strip, he wauld have said he was on the strip or asked for drag advice <img src="/forum/images/graemlins/smile.gif" alt="" />

Yep Easy I have RLTC. Works very well once you have tweeked the setting from standard.

Althought it's not cheap <img src="/forum/images/graemlins/grin.gif" alt="" />, I think it cost me about £470 inc delivery (it's about £1k retail <img src="/forum/images/graemlins/shocked.gif" alt="" />) but this was on a group buy with the SX200 forum. It was a relatively straight forward DIY fit, once I got over the nerves of cutting into my ECU loom and connecting into the ABS system <img src="/forum/images/graemlins/shocked.gif" alt="" /> <img src="/forum/images/graemlins/laugh.gif" alt="" />

of which you would have been the best person to respond <img src="/forum/images/graemlins/tongue.gif" alt="" />

haha it wasnt on a public road lol it was in an industrial estate ye i think the racelogic traction unit sounds good i might have to try that. i tried limiting the boost on my apexi put gear one to minus 50% but for sum reason it still boosts to 1.1 bar and my actuator is 0.6 bar so it should only be there.

I find my traction breaks in first above 0.9bar (a little more in dry warm weather) You should be able to limit this in the Apexi but then again I don't know the limitations of the in-gear boost function.

Don't take on M3 CSL's from a standing start. They've got RWD and much, much more grip.

You only started to reel him in at the end as he was probably coasting by that point having left you for dead. <img src="/forum/images/graemlins/tongue.gif" alt="" />

That was more my interpretation too.


BTW Genuine CSL's are rarer than hens teeth and you just happen to find one waiting to race you on an industrial estate. <img src="/forum/images/graemlins/wink.gif" alt="" />

na he wernt coasting we spoke after we only got to 90mph as he started braking. i was amazed by the rocket launch he had too a major lead! i knew they were quike off the line but heck not that quick off the line! lol

oh so it isnt that hard to fit then i thought it would be a job for barbz! i know somewhere, where i can get one for 630 so you think it works very well then? thats a good start! <img src="/forum/images/graemlins/laugh.gif" alt="" />

The M3 CSL is a real monster anyway. I suppose it depends on what sort of driving you do and how much you want to spend. You just have to think about how often you launch the car and whether it really warrants spending out the cash on a good TC system.

I suppose the question is, would you have kept up if you had TC already fitted?

lol i havent got a clue but one things for sure my car was faster in gear but in 1st n second gear i was spining the wheels <img src="/forum/images/graemlins/frown.gif" alt="" /> dont matter if i dont beat m3 csl's i just want good traction to be honest. 1st and second gear seem pointless with all that wheel spin. The car was deffinatly faster when standered in 1st not so much second. feels like i aint even moving. lol

oh n yes deffinatly worth it! <img src="/forum/images/graemlins/laugh.gif" alt="" />

Refit the standard EBV <img src="/forum/images/graemlins/laugh.gif" alt="" />, doesn't that limited power in 1st and 2nd or something to prevent wheelspin?!

lol ye it does i dont understand why my apexi aint doing it to be honest weird anyways i think im gona go for racelogic!

Seen 2 round my way here, one even with the number plate M3 CSL

You'd have though BMW GB would have bought that when they knew the CSL was due to be launched. <img src="/forum/images/graemlins/grin.gif" alt="" />

The Motec isn't worth it though as a traction control tool unless you're also thinking about alternative engine management. Fully setup it's a lot more than a Unichip + RLTC.

in theory the latest Motec traction control is better than RLTC because it utilises hall sensors rather than magnetic pickups (the standard ABS items) and therefore it is more sensitive especially at low speeds. It also has more options for what it does - i.e. you can retard the timing rather than cut, or retard then cut rather than cutting only as RLTC does. It can also cut either fuel or ignition, and can also retard the ignition to provide part or full boost launches.

I haven't compared the two systems in the 'real world' but would say RLTC is a very good bit of kit if a bit pricey.

csl are rare cars.

v. quick.
.

oh yeah , learn to control your right foot.

cheaper then traction control.

.

hehe ye i supose it would be. A little hard tho when all the power cums in like an on off switch with this .86 housing turbo. i duno, ye i supose i gota learn to control my right foot, rather have the traction conrol, control it for me tho lol, just easier that way. lol

and one last advise, don’t race any car from standing start! Its really the weak point of coops (yes, coop not coupé <img src="/forum/images/graemlins/tongue.gif" alt="" />) especially with M3s <img src="/forum/images/graemlins/wink.gif" alt="" />

ye ill take that into consideration next time lol
