Andre Posted November 18, 2006 Share Posted November 18, 2006 I've got a prologic traction control with launch button installed. But it was in the car when I bought it and I'm not sure if is working? Any one know what I should be looking for to tell me if it is doing the job. Thanks Quote Link to comment Share on other sites More sharing options...
Jake Posted November 18, 2006 Share Posted November 18, 2006 prologic is the make? Not RaceLogic? http://www.racelogic.co.uk/?show=Traction_Control-Technical-Launch_Control Quote Link to comment Share on other sites More sharing options...

Jake Posted December 4, 2006 Share Posted December 4, 2006 You driving an auto or manual?Launch control is for manuals only Quote Link to comment Share on other sites More sharing options...
Lucifer Posted December 4, 2006 Share Posted December 4, 2006 Launch control is for manuals only No its not if you have a High Stall. Quote Link to comment Share on other sites More sharing options...
Jake Posted December 4, 2006 Share Posted December 4, 2006 No its not if you have a High Stall.How does that work then? I don't see how Launch Control would make any difference to an auto. Please explain how you would use Launch Control on an auto. Thanks Quote Link to comment Share on other sites More sharing options...
Lucifer Posted December 4, 2006 Share Posted December 4, 2006 LImiting the overall reves and u are able to use full throttle so you can launch at WOT. In that case explain teh 2stage rev limit used in drag!?? Quote Link to comment Share on other sites More sharing options...
Jake Posted December 5, 2006 Share Posted December 5, 2006 LImiting the overall reves and u are able to use full throttle so you can launch at WOT. I still don't get it. With power braking the TC limits the revs anyway, even at full throttle. If this is what happens with Launch Control: You're on the start line, the gearbox is in Drive, you press the brake hard and when the time to launch comes you floor the throttle. When the revs reach the maximum the TC will allow you release the brake and the car starts moving forwards, rapidly. How would LC improve on that? In that case explain teh 2stage rev limit used in drag!??How are two stage rev limiters related to RLTC Launch Control? Totally different thing isn't it? I thought 2 stage limiters for primarily for manual transmissions too. Quote Link to comment Share on other sites More sharing options...
Miguel Posted December 5, 2006 Share Posted December 5, 2006 Dude also had launch control set up on his Jake and it worked well. But only with a higher stall point. You set the Launch ignition cut just before the flash point of the High stall or on it (Takes some of the stress out of the box while power braking too). Matt knows more than me about it as it was he that done it so I wont go on as I don't fully know . Quote Link to comment Share on other sites More sharing options...
Jake Posted December 5, 2006 Share Posted December 5, 2006 So it's a way of making (say) a 4000 high stall launch at (say) 3800? Weird. Is it just a way of compensating for a too-high High Stall TC or is there a good reason for it? I bet Dude was the only auto Supra in country that had it.

Miguel Posted December 5, 2006 Share Posted December 5, 2006 I think he may have been the only one back then, but then it would be rude of me to say he definitely was as I don't fully know. Lets just say your stall flashes at 4K with the go go pedal fully mashed. You yourself know that holding a power break is not good for heat through an auto. Now Imagine still holding it at 4k but with ignition/fuel cut( launch control basically a misfire ) so full torque for that set RPM on launch is not going through the torque converter and therefore not generating as much heat, torque converters work on a load basis not just RPM. What happens after that you would need to ask someone that has used it or is using it on autos. I don't know if the actual launch on the RTLC differs from the normal slip control and the launch has a finer setting to get max power for slip ratio. I have never had RTLC on my own cars and have never really dabbled or fitted them TBH, That is Matt's speciality so he or Martin I'm sure could tell more or correct me if I'm wrong. Hands up I only Know the very basics on how Dudes worked and how RTLC works, there are far more educated people than me that could tell more. Sorry chap:) Quote Link to comment Share on other sites More sharing options...
ajazyasin Posted December 5, 2006 Share Posted December 5, 2006 Ive got RLTC in my Soarer and I found the launch control cut the power too much. I found the best combination was power brake and tc set at 20% slip. The LC limiter sounds really funky when you are staged though!! Quote Link to comment Share on other sites More sharing options...
2jzhead Posted December 5, 2006 Share Posted December 5, 2006 This is probibly a noobie question but i just saw, keep your foot on the break and rev the car up, on an auto, wouldent that wreck the gearbox? i tried to do it in ours to do a standing burnout but it just moved.

ajazyasin Posted December 5, 2006 Share Posted December 5, 2006 maybe you're not pushing the brake hard enough? Each car is slightly different i guess. Quote Link to comment Share on other sites More sharing options...
