Chris and Alana Posted October 3, 2007 Share Posted October 3, 2007 I fitted RLTC recently and today is the first day with rain so off I went to an empty car park to see how well it works. Iv already allocated all wheels by jacking the car up and spinning them so I'm sure they are right and have a new dat file from terminator. Now when I floored it (adjuster set to 'wet') in a straight line my tires started slipping and the back end started to come out I didnt feel any traction control kick in at all. I take it this isnt normall behaviour. From what Iv read it should be hard to spin the tires with RLTC set to wet. What could be wrong? When I had the Diagnostic lead in it detects all 4 wheels and the LED blinks evenly and it detects my RPM speed. Any ideas. . . . The only part of terminators file I changed was the wheel allocations but that needed doing and I adjusted the launch control RPM to 10,000 as my engine cut out when I turned the unit off then on then of then on (it would cut out) and the adjustment sorted that. Would this affect it. I have an auto. Quote Link to comment Share on other sites More sharing options...
Mike B Posted October 3, 2007 Share Posted October 3, 2007 mine is highly sensitive on wet.. it hardly lets the wheels spin at all and the back end is locked in a straight line. even on dry it cuts in on tight roundabouts. sounds like the setup is off somewhere.

Pete Posted October 3, 2007 Share Posted October 3, 2007 It ought to have lots of engine cuts and the backend ought to not step out. I tested this doing a hard U turn on an unused road. Are your tyres ok? Quote Link to comment Share on other sites More sharing options...
Chris and Alana Posted October 3, 2007 Author Share Posted October 3, 2007 I put the standard traction control on and left the RLTC on its wet setting and on the way home I put the foot down on the dual carridgeway and the back slid out and the standard slip control came in first there must be something not right. Im confident the wiring is fine and I know it pics up all 4 wheel speeds and RPM. The car drives fine aswell it just seems that the RLTC isnt kicking in. Could it be because I altered the launch control rpm settings? Quote Link to comment Share on other sites More sharing options...

They are Goodyear Eagle F1's with over half the tread left all over. Quote Link to comment Share on other sites More sharing options...
Terminator Posted October 3, 2007 Share Posted October 3, 2007 Some thing is seriously wrong there. On my local test track, I have driven WOT all the way to 100+ in pouring rain, with RL set to wet. Tried again with RL turned off and span it 270 at 35- 40. Would you download the dat that is currently in your RL system and send it to me. Zip it before you send, I will check it for any errors straight away. Quote Link to comment Share on other sites More sharing options...
vvteye Posted October 3, 2007 Share Posted October 3, 2007 I'm sure my stock T/C had to be turned off when I had RLTC. Quote Link to comment Share on other sites More sharing options...
Ian C Posted October 4, 2007 Share Posted October 4, 2007 I'm sure my stock T/C had to be turned off when I had RLTC. You miss the point, Chris (or possible Alana ) did that as a test. And yes you are right, stock TC should be switched off. Under all circumstances tbh -Ian Quote Link to comment Share on other sites More sharing options...

Hi Phil I'm going to jack the back end up later today after work and see what happens when I spin the wheels (in gear and engine running etc) to see if it cut's in. If it doesnt I'm going to adjust the launch control settings and see if that helps. If I get no joy I'll send you the dat file I'm using. Thnaks for offering to have a look, your a big help Does the standard traction control fuse need to be pulled for RLTC to work? Or as long as it's switched off? In other words if the standard slip control was left in the on position would it stop RLTC from working? Quote Link to comment Share on other sites More sharing options...
Chris and Alana Posted October 4, 2007 Author Share Posted October 4, 2007 Ian just answered my question Thanks I did have the standard traction control turned off (by the button in the car) when I first tried it but it still didnt work I'll see what I can do later today and post up on my findings.

Ian C Posted October 4, 2007 Share Posted October 4, 2007 Termie should be able to tell you if there is something seriously amiss with the dat file. If you've got a laptop and the software you can datalog the system and it'll show you if it is attempting to do a level 1, 2, or 3 cut. If it's not attempting to cut it I'd say you've got a limit set sky high, have you inadvertantly raised the minimum RPM level to 10kprm as well as the launch control one? It'd never cut in if that were the case. However if it's logging a cut event then it's probably something to do with how it is wired into the injectors. -Ian Quote Link to comment Share on other sites More sharing options...
Chris and Alana Posted October 4, 2007 Author Share Posted October 4, 2007 the only limiters I have changed were 4 RPM settings in the launch control menu. I changed them from 0rpm to 10,000rpm after reading older threads regarding engine cut on auto's. It solved the problem but I cant think why that would affect the operation of the traction control. I have felt it cut the injectors before I allocated the wheels as they were all allocated wrong for my car from the old dat file so it was cutting quite abit. Im confident the injector wiring is fine. The car wouldnt start if that was wrong either would it? Oh the joy's of modern technology. . . .

T2 MSW Posted October 4, 2007 Share Posted October 4, 2007 Subscribed, soory for your issues. Perhaps ill back off with the install of min. So far ive done the power and ABS sensors to the loom, Think thats as far as I can go without starting on the injector wires. Hope it gets sorted soon.

Well if you've felt it cut already then the wiring should be OK, so it's got to be a config issue Termie will sort that out -Ian Quote Link to comment Share on other sites More sharing options...
Chris and Alana Posted October 4, 2007 Author Share Posted October 4, 2007 Update. . . I jacked the back end of the car up, put it in drive (adjuster set to wet) and pressed the accelerator and guess what, the car starts to cough and splutter so everything works fine there. However I did notice that when I changed the adjuster to check the other settings (dry, 10%, 20%) they all seemed to cut in at the same time. Is this just because the wheels are spinning so quick being off the floor? Another thing is that in the wet it didn’t seem to do it's job yesterday, maybe a job for terminator. oh yeah, when I pulled the traction control fuse to disable the standard traction control my O/D light kept flashing on and off (also turning over/drive on and off as the engine revs kept fluctuating) I pulled the little 7.5a fuse in the fuse holder in the engine bay (3rd one up, middle row I think) Is this the right one to pull? Thanks for all your help so far guy's, you have to love this forum Quote Link to comment Share on other sites More sharing options...
Chris and Alana Posted October 4, 2007 Author Share Posted October 4, 2007 Oh forgot to ask, can you adjust how sensitive the 'wet' setting is or only the other settings? Quote Link to comment Share on other sites More sharing options...
Terminator Posted October 4, 2007 Share Posted October 4, 2007 Altering launch settings should not make any difference to the function of RLTC in non launch situations. With the front wheels static and rears jacked up and rotating will make RL cut like hell. In road use the rears only have to move a few cm more than the fronts and RL will apply cut. Do you have a digi adjuster, or have you gone for the sensible option? Quote Link to comment Share on other sites More sharing options...
Chris and Alana Posted October 4, 2007 Author Share Posted October 4, 2007 I have the sensible option Phil and Yeah the engine did cut like hell with the back wheels off the ground so everything seems ok there. I did think myself that the launch control shouldn't affect the car but when I turned the adjuster off and on it would cut my engine dead and not allow it to fire up until I set the adjuster to off. Anyway I changed it to 10000rpm and it didnt happen again. You'll see in the file I sent what I've done (hope I didnt make a mess ) Do you know what fuse I can pull to disable the standard traction control? or is it a case of press the button everytime I get in.

Terminator Posted October 4, 2007 Share Posted October 4, 2007 It is better just to turn it off every time you start the engine. Pulling a fuse will have undesirable effect if you have an auto box. No problem if the are manual. Something weird is going on, you should not have to do any of the things you have listed. Is your RPM source dedicated or does some after market item share it? Is the earth for RL on clean bare metal? I have the sensible option Phil and Yeah the engine did cut like hell with the back wheels off the ground so everything seems ok there.

No problem if the are manual. sorry for the hijack but I want to turn my standard traction control off because it keeps coming on a 2 mph, going to snow mode. But the button to turn it off only turns off "snow" when it appears, it doesnt work any other time. Anyone know why? Quote Link to comment Share on other sites More sharing options...
Chris and Alana Posted October 7, 2007 Author Share Posted October 7, 2007 Just incase anyone might be interested, My RLTC seems to be working spot on. I had a fiddle with the dat file in the middle of the week and tried it out in the dry, it was simply amazing, wouldn’t let the backend go anywhere I had to wait until it was wet to test it properly though (today was that day) and oh my god I never realised just how much the back wheels slip when the roads are wet. I again took it to a nice quite spot of tarmac and tried to spin the car, RLTC takes a sissy fit but controls the rear end a treat. I simulated a 90degree turn as if I was pulling out of a junction a little to quick and it worked really well indeed, again controlling the backend and keeping me on the road. I then floored it in a straight line and there was no back end stepping out just the odd occasional soft misfire keeping me pointing in the planned direction I am a very happy chapy that things are now working as they should and I would have to say that it is a MASSIVE improvement over the standard 'slip control' I wish I had bought it earlier. Also a big for everyone's help, especially terminator who helped me along in my times of need. Quote Link to comment Share on other sites More sharing options...
