cowboy bebop Posted February 23, 2004 Share Posted February 23, 2004 Hi guys, I'm a regular on the SupraForums.com and they refered me to this forums to answer my Racelogic Traction Control question. I'm going to be involved in a highspeed race, and want to have as little wheelspin as possible. Can the RLTC control wheelspin at the 1000-1400rwhp levels? I want to make sure this is the right unit for my needs. Thanks in advance guys, Eric Link to comment Share on other sites More sharing options...
Nick Posted February 23, 2004 Share Posted February 23, 2004 Not a problem, it's all down to the DAT file. It's possible to completely eliminate wheel spin regardless of how much power you have. "Terminator" is the boards expert on the RLTC and can supply a DAT file specific to your requirements. If you're a paid up member of the board it's free, otherwise there's a small fee. It's a fantastic bit of kit, you won't be disappointed. Link to comment Share on other sites More sharing options...
Adam W Posted February 23, 2004 Share Posted February 23, 2004 Don't think anyone has used it over here in such a high-power application on the supra, but I believe it has been used successfully in things like F1 cars and GT racing cars with very high power-to-weight ratios.

Terminator Posted February 23, 2004 Share Posted February 23, 2004 Hi and welcome to the MKIV.net BBS RLTC, works by comparing front and rear wheels speeds, you decide how much slip you wish to allow. Race Logic recommend 10 slip for the best take offs. The system detects many times a seconds and cuts injectors accordingly, so power is not an issue. As said above it has been use in F1 and other high power to weight cars in motor sport. I can’t see the power levels you describe being an issue, however a little "dat" tuning may be required to get the best from your car. We have a little bit of software that was written by Graham Rudd of this BBS that allows for easy setup via a laptop. RL have their own software based on Grahams system but we have found it not to be bug free so our advice would be to use Graham’s software which is free and 100% reliable RL do a range of RLTC systems you may want their top system with live log recording to enable the fine tuning you may require. It is possible to have a passenger monitor the system live but at the power you are using a recording may be more reliable. I would offer to come and sit in the passenger seat and set it up for you for you but I can’t swim that far. To get a definitive answer try [email protected].

Keith C Posted February 23, 2004 Share Posted February 23, 2004 Phil, for the benefit of our newcomer who may be intending to use nitro, can you mention the limitations of RLTC when used on a car using nitro? Link to comment Share on other sites More sharing options...
cowboy bebop Posted February 23, 2004 Author Share Posted February 23, 2004 Thanks guys for the responces. It 's all really informative. But yes, I'd like to know the limitation for when I shoot N2O. Eric Link to comment Share on other sites More sharing options...
Terminator Posted February 23, 2004 Share Posted February 23, 2004 Basically NOS and RLTC don’t mix, putting the two together could be very dangerous, due to a very lean mix in a cylinder while its injector is cut. It might be possible with the RLTC spark cut system but all that NOS and fuel is going to end up round your waste gas pluming and it will ignite somewhere. My knowledge of NOS systems is some what limited but I understand that the “injectors” are rather crude and just add NOS and fuel mix via thin tubes using a mechanical rather than electrical control so any RLTC control of the NOS fuel input would be very difficult. I think there was a thread some while ago where RL were quoted to say you could run up to a 150 shot safely with RLTC, but it was not very convincing. I think Nathan from TDI said something about setting NOS activation above 1.2 bar might be OK as RLTC when activated rarely lets the car boost above 1.0 bar. I know there are mixed views on this, but personally I would not use the two together at the same time, I would want the NOS switch to cut power to RLTC so it was disabled and there was no chance of blowing a hole in a piston. This would rule out NOS in the early stages of a run when you want RLTC to help keep traction. Link to comment Share on other sites More sharing options...
Aerotop Dave Posted February 23, 2004 Share Posted February 23, 2004 [highjack] Uploading new DAT files into the beastie - what do you need to do this, how easy is it, and once it's done is there any (re)calibration required? [/highjack] Link to comment Share on other sites More sharing options...
Terminator Posted February 23, 2004 Share Posted February 23, 2004 If you get a dat tuned to you car it will workwell, you can fine tune if you wish to experiment using Graham's application. There are about 40 settings to play with so be careful. Link to comment Share on other sites More sharing options...

Keith, just for the record and to avoid confusion Nitro and Nitrous are 2 totaly different things , Nitro is Nitromethane a fuel that is used in Top Fuel Dragsters and Funny Cars , Nitrous Oxide is a gas used by Dentists and Petrol heads to go a bit faster Dude:flame Dev Link to comment Share on other sites More sharing options...

Terminator Posted February 23, 2004 Share Posted February 23, 2004 I thought Cowboy was talking Nitrous Oxide not Nitro I assumed that any fuel fed through the normal injection system and thus controlled by RLTC would be OK as on each cut you have no fuel to ignite.

There are about 40 settings to play with so be careful. Sorry, I might not have explained myself very well. What I meant was if I wanted an ultra-conservative file for winter (for example) how easy is it for you to send me that and for me to load it up? Once I've done that, do I need to calibrate the thing or is it just a case of loading it up and away you go? Link to comment Share on other sites More sharing options...

Not too much of a Hijack as this is still relevant to putting RLTC in a car;) If you have Grahams app, and a laptop it is easy to load. My dats obviously don’t come with wheel allocations to match your car. My advice would be to RECEIVE your own internal dat which should have the correct allocations and save this as your master dat on to your laptop. Also keep a written copy of the wheel allocations. You can then copy the wheel allocation into the dat I send, SAVE it with a name of your choice then TRANSMIT this new dat to your RLTC unit. If you don’t have Grahams app I can send it to you.
