Paul -C- Posted April 5, 2005 Share Posted April 5, 2005 I'm having some traction problems with the car, but it only happens occasionally. I have RLTC and it seems to be working fine, but now and again I seem to lose traction way too easily. Tonight for instance, I was going round a roundabout and pressed the gas a little early going round. I didn't stamp down on the gas or anything, just pressed down a little. The full car slid round for about 2 metres. This was with RLTC on Wet, so there should be no loss of traction at all. When I took it to a car park I couldn't get it to slide or lose traction at all. Even sometimes in the dry it feels like its on castors occasionally, usually around roundabouts. I'm also getting a knocking from the rear driver side wheel, so I'm thinking the shocks are a bit knackered. I've got the Toyota Bilstein on just now, but they've done 53k miles, so are probably due to be changed. Does it sound like shocks, or is could it be something else? Cheers guys!

hadyn Posted April 5, 2005 Share Posted April 5, 2005 are your tyres past their sell by date??? worn tyres can lead to a loss of traction obviously Link to comment Share on other sites More sharing options...
Paul -C- Posted April 5, 2005 Author Share Posted April 5, 2005 I've got Goodyear F1s with loads of tread left. Only done around 4k miles with them. Link to comment Share on other sites More sharing options...

Paul -C- Posted April 5, 2005 Author Share Posted April 5, 2005 diesel on the road. It's happened quite a few times though, both in the dry and the wet, all in different places. I think it's something to do with the suspension, especially since I'm getting a knock from the rear drivers side wheel. Link to comment Share on other sites More sharing options...
SKI Posted April 5, 2005 Share Posted April 5, 2005 I've had a few scares with my RLTC, even on wet, back end went west the other day whilst I was cruising past an Audi TT (my suspension id fine). Did you deffinitely have the stock turned off! Link to comment Share on other sites More sharing options...
Paul -C- Posted April 5, 2005 Author Share Posted April 5, 2005 Yeah the stock traction ecu has been out of the car for a year. Last month I was playing around in a wet car park, trying to make the car lose traction. The car handled perfectly on the wet setting, couldn't make it slide at all. Then as soon as I turned out of the car park the back end slid away out, with only a little acceleration. Link to comment Share on other sites More sharing options...
SKI Posted April 5, 2005 Share Posted April 5, 2005 I get the same, although, it does say somewhere that you will get slip on hard lock turns from stationary when your giving it some (I'm sure of this). Maybe it's time for a more aggressive dat file. I regularly get slip in wet conditions even with wet mode on, I'm gonna' have a play mine this weekend, I know for sure that the tyre stettings are not quite right in the dat file. Will let you know how this goes. Link to comment Share on other sites More sharing options...

tbourner Posted April 6, 2005 Share Posted April 6, 2005 Have you tried jumping up and down on the back of the car? I mean to test the shocks I haven't gone mad!! Link to comment Share on other sites More sharing options...
Terminator Posted April 6, 2005 Share Posted April 6, 2005 I have provided over 90 dats for MKIV owners, a few have altered in the RLTC unit with use, about three. Below 14Kph rltc does noting anyway. It could be that your RLTC revlimit has some how altered. If the suspension is knackered and the wheel is all over the place I would have expected you to feel maximum cut if your speed and RPM are above the threshold levels. May be your dat is playing up or you have an intermitant fault in your abs sensor circuit Useing the RLTC version one software did cause problems with wheel settings which rendered RLTC usless. If you want to take a copy of the dat in your car I will look at it for you. Link to comment Share on other sites More sharing options...
Ian C Posted April 6, 2005 Share Posted April 6, 2005 Perhaps the sliding is taking place below the threshold of RLTC cutting in, say 10mph? -Ian Link to comment Share on other sites More sharing options...
tbourner Posted April 6, 2005 Share Posted April 6, 2005 14kph is quite slow, can't see anyone going 8 and a bit mph round a roundabout!!! Link to comment Share on other sites More sharing options...
Ian C Posted April 6, 2005 Share Posted April 6, 2005 Yeah but the setting might be too high. It's explain the junction thang a bit. Meh -Ian Link to comment Share on other sites More sharing options...
Paul -C- Posted April 6, 2005 Author Share Posted April 6, 2005 If you want to take a copy of the dat in your car I will look at it for you.Thanks Terminator, I've PMd you my settings file and also a dat file I recorded on a drive yesterday.

SKI Posted April 6, 2005 Share Posted April 6, 2005 Just checked my dat file with the latest version of the RLTC software from their website. Found that the pulse rate on the wheels was 40 not 48 also the tyres sizes and profiles were a bit off. Will be interesting to see how much difference this makes when I drive her tomorrow... Had a little play with the new "induced missfiring" options too, nice touch by RLTC, it allows you to demo what the system does to the car under slip.

SkyJawa Posted April 6, 2005 Share Posted April 6, 2005 Sounds very similar to when my Supe died Link to comment Share on other sites More sharing options...
SKI Posted April 6, 2005 Share Posted April 6, 2005 How did she die dude? Hope it wasn't too painful! Link to comment Share on other sites More sharing options...
SkyJawa Posted April 7, 2005 Share Posted April 7, 2005 Yeah, quite painful. Dry industrial road, less than 30 mph straight on round roundabout done it a million times, just filled up, bloke in back and front, back stepped out left I corrected and it snapped 180 degrees back right, went off road backwards and sideways into a concrete block. I had Eagle F1 tyres, about 2k miles on them, the proper alignment set to Lance settings and the RLTC which was on the Dry mode setting allowing 5% slip I believe...........

Paul -C- Posted April 7, 2005 Author Share Posted April 7, 2005 Sorry to hear about that Neil Here's a snap shot of the log file graph I recorded the other day with setting on Wet, even though it was a dry day (wanted RLTC to cut in hard to show on the graph). It shows 2 wheel speeds, I've hidden the other 2 since they show the same readings as channel 1. It also shows Cut and Revs. As you can see from the graph channel 4 seems to show silly speeds during some launches. Also the revs seem to vanish 2/3 of the way through the log. http://www.paulcorrigan.com/rltclog.jpg Would I be right in thinking that my Rev connection might be loose or something?

Paul -C- Posted April 7, 2005 Author Share Posted April 7, 2005 Just heard back from RLTC that the rev signal vanishing is a software glitch with the rltc log program, so it's nothing to worry about. Link to comment Share on other sites More sharing options...
