r2ck_p Posted December 25, 2012 Share Posted December 25, 2012 Hi guys, Merry Christmas, hopefully you can help. I had the RLTC fitted recently and the controller was set to wet. Drove out of the work carpark on to a busy main road in the rain and there must of been some spin on the rear wheels. This made the SNOW mode / light appear on the dash and the car ran with limited power. I turned SNOW mode off manually by pressing the OFF button and the dash light disappears and all is good again. However is Snow mode supposed to come on if I have RLTC fitted as seems a bit pointless to me to have RLTC fitted if it’s just going to go in to SNOW mode every time there is some wheel spin. Please advise. Cheers Quote Link to comment Share on other sites More sharing options...
dangerous brain Posted December 25, 2012 Share Posted December 25, 2012 I would argue that it hasn't been fitted right if the stock traction is cutting in before the RLTC is. In fact if the stock traction is still active with RLTC then it definitely isn't installed or commissioned correctly Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted December 25, 2012 Share Posted December 25, 2012 You need to turn the stock traction control OFF when using the RLTC. It is left functional as a safety feature. RLTC isn't the most reliable of devices and if it croaks you still have some traction control functionaility. Permanently disabling the stock TC is not something I normally do when fitting Racelogic.

Havard Posted December 25, 2012 Share Posted December 25, 2012 I thought RLTC would take precendence over any stock TC. Seems pointless if you break traction and snow mode kicks in. Do you have to manually switch stock TC off for RLTC to work then? H. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted December 25, 2012 Share Posted December 25, 2012 Yes, unless you permanently disable it. Stock TC resets to ON every time the ignition is keyed. Quote Link to comment Share on other sites More sharing options...

Ai but stock TC is no-where near as sensitive as RLTC's least sensitive mode is it? Snow mode trigger is there for complete and utter traction loss isn't it? I know on my aristo you had to really lose the car on snow before that would trigger or select it on the switch. If it's triggering with slight wheel spin and it didn't before then by defacto the only thing that's been changed is the RLTC therefore it must be the RLTC instal that is causing this issue?

Radio Posted December 26, 2012 Share Posted December 26, 2012 Wonder what Racelogics point of view would be. Surely they have not designed a system that they expect you to share with the original system. Just dosen't seem to make sence. Anyone work for Racelogic ?

SteveC Posted December 26, 2012 Share Posted December 26, 2012 I found the stock TC to be very dangerous indeed. I was almost t-boned once when the TC cut in whilst pulling out of a junction . When I fitted the RLTC I permanently disabled the stock TC. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted December 26, 2012 Share Posted December 26, 2012 As a trader I have to be very careful about disabling stock safety features. I would rather customers themselves did this. I agree the stock system can leave you in limbo if it cuts in when you are pulling out in front of a juggernaut I always leave the stock TC system active, but of course, the option still exists to manually turn it off each time you key the ignition.

r2ck_p Posted December 27, 2012 Author Share Posted December 27, 2012 The car always pre and post the RLTC went in to Snow Mode with the slightest of wheel spin. I didn't realise you have to turn the stock traction control off everytime you turn the ignition on for the RLTC to be operational. It doesn't say the stock TC is on when you start the car, there is no lights to indicate this. The car just goes in to Snow Mode when you get spin. Then and only then does the Snow Mode light appear allowing you to press OFF to turn it off. How do I know if stock TC is on or RLTC is on ?

Branners Posted December 27, 2012 Share Posted December 27, 2012 RLTC with the best config file and settings will react faster than the stock system and in theory you wont see the stock system kick in at all. The range of variables on RLTC means it can either be a brutal traction control system or infact operate without you knowing it is doing its thing. I do find the stock traction control on a facelift supra kicks in at the most random times, so disabling it does make some sense. I would also NOT run RLTC in the snow, they say in their guide that its really not good for the engine, so keeping the stock snow mode available does make some sense.

Pixelfill Posted December 27, 2012 Share Posted December 27, 2012 IIRC the dat files for the RLTC are set up to not operate below a certain speed, so setting of from stationary it won't be functioning, this might explain why the stock tc is kicking in before the RLTC.

msmile Posted December 29, 2012 Share Posted December 29, 2012 (edited) I have RLTC installed and never had problems. My stock TC is permanently disabled (by removing a fuse from the fuse box). RL states that in any case of the RLTC malfunction , the thirst thing to happen is a total fuel cut off, so that's not very dangerous even if RLTC fails, so I think theres no need to "insure" with completely unstable stock TC. IIRC the dat files for the RLTC are set up to not operate below a certain speed, so setting of from stationary it won't be functioning, this might explain why the stock tc is kicking in before the RLTC. Never experienced that. Even on launch or 10% modes it does work when the boost comes up on the 1st gear, and you will never do a burnout if its on.

I know that's not true because I had an RLTC unit fail on me. It introduced noise to the wheel sensor lines and caused the ABS to fail, and also stopped controlling traction altogether. All the fuel injectors carried on working though. This was diagnosed by: a) Matt Harwood and myself monitoring the wheel sensor signals with a laptop (apparently I could spin the rear wheel at 153mph) b) Swapping the RLTC unit for another one fixing the problem immediately and permanently c) Shaking the broken RLTC unit emitted a rattling noise -Ian Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted December 30, 2012 Share Posted December 30, 2012 (edited) I have a copy of the file if the OP wants to fiddle with it. Facelift cars stock TC seems to operate differently to earlier cars. I have used the DAT file on many facelift cars with good results. If he doesn't want to manually turn off the stock TC each time, he can disable it entirely. But it's something I prefer the customer does, for obvious reasons, these days If the power to the RL unit fails, there's no injector signals to the injectors. So the engine won't run, or suddenly stops. Whether that's good or bad depends on what you are doing at the time. Idling in standing traffic in the fast lane of the M25, or trying to start it in the garage at home might provoke different scenarios.

msmile Posted December 30, 2012 Share Posted December 30, 2012 (edited) Ian, did the ABS started to interrupt when it got noise from RLTC? Chris - would you disable stock TC on your car with RLTC, or is this this thing not the right one to trust?

Ah well that isn't normal AFAIK so you may want to have that looked at first as RLTC can't do anything if the TC system is coming in before it.

r2ck_p Posted January 3, 2013 Author Share Posted January 3, 2013 There should be a dash warning light saying it's off. Tested it yesterday, yes the dash warning light says it’s off, when you press the snow mode off button. So am I right in thinking the RLTC will ONLY operate if the Snow Mode off button is pressed every time the car is started? Is there anyway of definitely knowing the RLTC is working, as little worried turning my stock TC off in this weather just in case the RLTC is not operating or functioning properly. Don't want to end up down an embankment. Cheers Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 3, 2013 Share Posted January 3, 2013 The traction control, as I said to you, is not a catch all for exuberant driving in poor conditions, or any conditions, so as with any performance mods, you use them at your own risk. Yes, you need to turn the stock TC off for the RL to work. You could, if YOU think it safe, disable the stock TC. I can e-mail you the map in your unit to look at or play with. You can test the RL by jacking up the rear wheels and being absolutely certain it can't fall off the stands, run the rear wheels. I e-mailed you the manual, the test procedures are in there. I tried it on wet grass, and a wet road and it worked fine when it left here. Every RL I have fitted has required the stock TC to be manually turned off each time. The stock TC will automatically re-engage each time you key the enghine off and on. HTH. Quote Link to comment Share on other sites More sharing options...

JMB Posted February 22, 2013 Share Posted February 22, 2013 Hi every one !! I did some unsuccessfull research. I wtb a RL traction control + launch control. How do work (if it does) the launch control on a AT (my car is tip tronic) car ? I read everywhere you have to setup the RL, I may need some more details... Meaning should I be able to do it myself or I should pay someone to travel and setting it up for me ! Thanks Quote Link to comment Share on other sites More sharing options...
