Axle Posted November 6, 2008 Share Posted November 6, 2008 Wondering if anyone has experiecned this with their RLTC unit. Basically mine intermittently cuts my engine out completely. So it basically stalls. Even Racelogic themselves are baffled. As i sent them a reading and they said my ABS sensors seemed fine, and there wasnt an obvious reason as to why it was doing this. I only use it in Wet weather tbh but its cut out on me as im entering roundabouts and obviously thats pretty dangerous. Had this problem for a few months now, and still none the wiser. Oh, the Actualy Racelogic unit itself was sent back. and they have replaced the PCB, so its effectively a new unit. I have an Emanage Ultimate installed, so done know if this may have somthing to do with it, but doubt it. Anyone experienced this? Quote Link to comment Share on other sites More sharing options...

In the end I had to rewire the whole lot basically my RLTC took the injector signals from the Stock ecu then passed them to the EMU. This caused the problem so in the end I put the RLTC on the injector output wires from the EMU and it was much better however still did it occasionally! I also sent it off to Racelogic and they confirmed that everything was prefect! In the end I took the EMU off the car when I was going AEM anyway to test it and it was perfect and never cause any stalling or cut out. Then did the same thing with the RLTC and again perfect. Basically then I sold it and the EMU. Quote Link to comment Share on other sites More sharing options...
Pete Posted November 6, 2008 Share Posted November 6, 2008 The fuse holders are pretty poor, I've seen two now which do not give a good contact. First thing to try is to replace the fuse holder with a better one. Quote Link to comment Share on other sites More sharing options...
michael Posted November 6, 2008 Share Posted November 6, 2008 Didn't RedM have this issue with his car when he first got RLTC? I forget what the fix was now but a search might yield some answers. Quote Link to comment Share on other sites More sharing options...
Axle Posted November 6, 2008 Author Share Posted November 6, 2008 (edited) Cheers lads. Sorry for my ignorance but fuse holder on what Pete? Or rather where is it located? I will try a Search Mike thanks. (Edit: Found the thread) http://www.mkivsupra.net/vbb/showthread.php?t=62986&highlight=rltc+stalling This doesnt seem identical to my issue. As with Red it would happen when his unit is switched on from off. Mine is very intermittent. Will happen somtimes, and when it does it will happen continually, and on other occasions wont happen at all. I would ideally like to keep the RLTC for wet days. In the end I took the EMU off the car when I was going AEM anyway to test it and it was perfect and never cause any stalling or cut out. Then did the same thing with the RLTC and again perfect. Sorry mate, this confused me abit. Did you bascially get it working properly with the Emanage Ultimate, by rewiring before you sold it off? Odd, because Racelogic said they have never had this kind of problem before. Edited November 6, 2008 by Axle (see edit history) Quote Link to comment Share on other sites More sharing options...
paul mac Posted November 6, 2008 Share Posted November 6, 2008 i had a cutting out issue but it was when going to pull away from a slow speed rolling start or setting off from a junction, it turned out i had wired the rpm signal in with my SAFC so effectively 2 wires on the same output messed with the RLTC brain, i swapped the RLTC onto another rpm signal and all was well again Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted November 7, 2008 Share Posted November 7, 2008 The fuse holder is the black fuse housing that comes as part of the RL loom. I concur, they can be suspect. Quote Link to comment Share on other sites More sharing options...
Axle Posted November 7, 2008 Author Share Posted November 7, 2008 Cheers Chris. Will try replacing that, but i have a feeling it may be to do with the wiring setup then. As before the EmanageU was fitted all seemed well. Quote Link to comment Share on other sites More sharing options...
Terminator Posted November 7, 2008 Share Posted November 7, 2008 (edited) Racelogic get very few faulty boxes. I have been in discussion with them for a misfire on my car, that only occurs when the race logic is connected to the loom. I have rewired and rewired the Racelogic loom ends that I made up over eight years ago. I checked the plugs that go into the Raclogic box, and found some of the female connectors were very loose when I inserted a new male pin. Up until recently my Racelogic unit has sat undisturbed behind a carpet,working perfectly. Since moving it several times, I am having real problems. I fell that its the plug connections are responsible Edited November 11, 2008 by Terminator (see edit history) Quote Link to comment Share on other sites More sharing options...

Axle Posted November 7, 2008 Author Share Posted November 7, 2008 Cheers T. So should the Racelogic be wired up from the stock ECU or from the EMU? Quote Link to comment Share on other sites More sharing options...
Ian C Posted November 7, 2008 Share Posted November 7, 2008 Give RLTC the TACH signal, everything else the IGF one. I had this as well, twice. The second time was a genuinely faulty unit (put it this way - it rattled) and it'd kill the car to the point where I couldn't even start it. But the first time was a combination of wheel speed differences and the minimum RPM setting. Coming out of junctions it'd cut all the power. I think I upped the minimum differences by 1mph and the minimum revs were set at 2000, I can't check though as I don't have the software handy. Suffice to say after those tweaks it never caused a problem again. I think it's an issue with limited slip diffs. -Ian Quote Link to comment Share on other sites More sharing options...
Axle Posted November 7, 2008 Author Share Posted November 7, 2008 Ian, Mine rattles too. Or atleast it has a rattle like there is movement inside the Unit. But Racelofic said they replaced the board,and the same rattle persists. Racelogic didnt seem to be concerned about this when i mentioned it. Should this not be the case. Also this problem i have is very inconsistent. I drove the car for 30 mins earlier and there was no issue. However it seems to happen when the car has been on for a lenghty period of time. Also, how do i check for the tach signal? Quote Link to comment Share on other sites More sharing options...
Ian C Posted November 9, 2008 Share Posted November 9, 2008 Oh no this was a proper bit-fallen-off-the-board rattle, you could hear it moving around from one end of the case to another. I think you just need to up the minimum difference between the wheels by 1mph (or kph?) and set to minimum RPM at 2000 or 2500rpm. The TACH signal is one of the ECU wires, you'll need a wiring diagram. I've changed PCs at work and haven't got any of my Mkiv resources on this one yet so I can't tell you which -Ian Quote Link to comment Share on other sites More sharing options...
Axle Posted November 11, 2008 Author Share Posted November 11, 2008 Ok Ian i will give that a go cheers. Only thing is, this problem occurs only after a long while of driving the supe, and even then, it doesnt always occur. Id have thought it would be more consistent if it was an issue amongst the settings. But its worth a go. Quote Link to comment Share on other sites More sharing options...

Axle Posted November 11, 2008 Author Share Posted November 11, 2008 this could indicate a heat related issue, where abouts is the unit located ? Behind passenger footwell. I thought the same, but Racelogic are not convinced. Quote Link to comment Share on other sites More sharing options...
imi Posted December 21, 2008 Share Posted December 21, 2008 RacLogic TC must have its own dedicated rpm signal. Anyone got any pointers as to where the dedicated RPM signal can be pulled from? Quote Link to comment Share on other sites More sharing options...
paul mac Posted December 21, 2008 Share Posted December 21, 2008 Anyone got any pointers as to where the dedicated RPM signal can be pulled from? imi there are 2 dedicated rpm signals on the ecu, have a look on here http://www.apexi-usa.com/pdfWiring/7.pdf you want drawing T7-b c or d there all the same, remember this is a diagram looking at the socket of the ecu as if the plugs were removed Quote Link to comment Share on other sites More sharing options...
imi Posted December 22, 2008 Share Posted December 22, 2008 Thx Paul as I am running an AEM ECU the RPM pinouts are different. AEM PIN OUT DIAGRAM Is it absolutely imperative that the RLTC is the only device connected to a dedicated RPM signal on the ECU or can it share it with say a speed display device? Quote Link to comment Share on other sites More sharing options...
imi Posted December 22, 2008 Share Posted December 22, 2008 Ok guys, I have wired it up using 16A on the AEM as it is a dedicated RPM output. I also have a RPM Gauge wired into the same output so hope that that is ok for the RLTC. The RPM light is now flashing so I am expecting it to now be fine. When I manage to fins a USB > Serial adapter I shall plug in a laptop to verify. Quote Link to comment Share on other sites More sharing options...
imi Posted December 23, 2008 Share Posted December 23, 2008 Car is flying now.....seems to have done the trick. still will confirm using a laptop. Quote Link to comment Share on other sites More sharing options...
