lee_kelsey Posted July 10, 2002 Share Posted July 10, 2002 Guys, The supra I recently purchased has the RLTC system, I did not get a manual or any instructions with it, and therefore would like to know if anyone can tell me how the launch control works. Advice/comments appreciated. Link to comment Share on other sites More sharing options...
Guest Martin F Posted July 10, 2002 Share Posted July 10, 2002 Quick Guide :- 1. Stop the car. 2. Make sure you are at idle and press the green button. 3. Engage clutch and put into first. 4. Floor the throttle and you should see the revs raise to the preset limit. Usually about 3,000 rpm. 5. Release clutch and ensure you keep the throttle to the floor. If the revs don't seem to limit anywhere then try the process again. You can change this rev limit either by use of the knob and button or a laptop but i don't have the procedure to hand. It is a great feature for a manual car but i don't seem to get to use mine often enought. Also try it at different slip settings. Link to comment Share on other sites More sharing options...

I have a green button on my centre console and the adj trac control knob which is near the dash light dimmer! ??? Link to comment Share on other sites More sharing options...
Guest Martin F Posted July 10, 2002 Share Posted July 10, 2002 They're the ones. Sounds like Racelogic did your original install. Link to comment Share on other sites More sharing options...

Guest Martin F Posted July 10, 2002 Share Posted July 10, 2002 Nope, once you have done the launch all will go back to normal. Link to comment Share on other sites More sharing options...

Terminator Posted July 10, 2002 Share Posted July 10, 2002 Lee, if RL did your install, your internal data file may not be the best you can get. If you have a laptop and a link cable we can sort you out with a file that does the business. Link to comment Share on other sites More sharing options...
Mark Ayling Posted July 10, 2002 Share Posted July 10, 2002 And if not, I have a laptop - what data cable is it? RS232? Link to comment Share on other sites More sharing options...
Terminator Posted July 10, 2002 Share Posted July 10, 2002 Yes, but it has a RL plug on the other end, the link cable is RL supply only. We could always arrange a meet to sort it out My cable is very accessible. Link to comment Share on other sites More sharing options...
Mark Ayling Posted July 10, 2002 Share Posted July 10, 2002 Are you going to TorqueIC on Sunday Phil? Link to comment Share on other sites More sharing options...
Terminator Posted July 10, 2002 Share Posted July 10, 2002 No I am in Middlesborough for the weekend. I am sure there are others going that will have a cable. If you can sort that out I can send a dat file and a copy of Grahams app, the rest is easy. Link to comment Share on other sites More sharing options...
Mark Ayling Posted July 10, 2002 Share Posted July 10, 2002 Cool - if you email me the relevants I'll take my lappy along and see if someone else has a cable. Cheers, Mark. Link to comment Share on other sites More sharing options...
lee_kelsey Posted July 10, 2002 Author Share Posted July 10, 2002 Nice one guys! I did give it a try tonight and it doesnt seem to work as Martin suggested! I tried the following several times, but the revs just kept shooting way over 3000! 1. Stop the car. 2. Make sure you are at idle and press the green button. 3. Engage clutch and put into first. 4. Floor the throttle and you should see the revs raise to the preset limit. Usually about 3,000 rpm. 5. Release clutch and ensure you keep the throttle to the floor. If the revs don't seem to limit anywhere then try the process again. You can change this rev limit either by use of the knob and button or a laptop but i don't have the procedure to hand. Any more suggestions? Or will this dat file sort the problem? If any one has a cable and can bring it along to Torque on Sunday, would be much appreciated!

Guest Martin F Posted July 11, 2002 Share Posted July 11, 2002 Best to link up a laptop and using Graham Rudd's application you can see exactly what the launch control rev limit has been set to. I am assuming you did have the RLTC unit on, i.e. no red LED showing ? Mark - Justin may well have an RLTC unit in stock that you could borrow the lead from.

I know the previours owner who had it installed said he never used it! I am wondering whether its ever been setup or infact the little button may just not be working! although the adj trac ctrl works fine! Link to comment Share on other sites More sharing options...
Guest Martin F Posted July 11, 2002 Share Posted July 11, 2002 Naaaa i'm sure it will work just need to hook up a laptop and check all the settings. Racelogic probably set the launch revs at something like 9,000rpm Idea I think it may be an idea for somebody to scan their RLTC manual so that it could be put as an online reference on here.

Turn off ign. turn it on and start car press green button (keep it held in) rev to where you want it to set the LC let go of the button turn off engine. to use it do what MF said Link to comment Share on other sites More sharing options...

Doughie Posted July 12, 2002 Share Posted July 12, 2002 Lee Hardhead's right on the procedure for setting the rev-limit. But it should have been set already which is a bit odd. I had RLTC with Launch control, and they usually come set with the Launch set to about 4000rpm. When i was at Santa Pod, (ZERO grip) i used the press-and-hold-green button procedure to lower the revs at launch, due to the lack of grip. 4000rpm is good for a nice tarmac road though. At Santa Pod, I lowered it to about 2500rpm. 2 other things that might help (when actually using the LC) : 1) probably has no effect but i'll mention it anyway is that when i used launch control, I engaged 1st gear and THEN pressed and released the green button. (Martin said to do it the other way round). It might make no difference, but try that way : clutch, 1st gear, press and release green button, foot flat on throttle (revs should "shimmer" around your set rev limit) and then clutch in pretty smartish. Obviously if you slip the clutch you'll burn the thing out and that a £500 job to fit a new clutch ! 2) Make sure that when actually using LC (i.e. not when setting the revs) , press AND RELEASE the green button. It won't work if you press-and-hold- the green button for the actual launch. Link to comment Share on other sites More sharing options...
