Kevin Huntley Posted October 23, 2002 Share Posted October 23, 2002 After having the system installed I have just uploaded the latest DAT file provided by Phil (Terminator) and I can not rev past 4000 RPM in any gear its as if the launch control is permently active. Has anyone had this problem and how can I solve it? What am I doing wrong? I have tried the launch control and it seems to be working OK holding the revs at 4000 RPM.

Guest Martin F Posted October 24, 2002 Share Posted October 24, 2002 Does the diagnostic LED flash with engine revs ? Quote Link to comment Share on other sites More sharing options...
Kevin Huntley Posted October 24, 2002 Author Share Posted October 24, 2002 Hi Martin, Yes it does. Martin you have a 6 speed and RLTC. Would it be possible for you to send me a copy of your DAT file so I could give that a go. I think the DAT file I have has only been used on an automatic so maybe that is causing some kind of problem. My email is [email protected] Thanks Quote Link to comment Share on other sites More sharing options...
Guest Martin F Posted October 24, 2002 Share Posted October 24, 2002 On it's way. Quote Link to comment Share on other sites More sharing options...

My email is [email protected] Thanks No it was a 6 speed file, but I did find an error, but, with out running the file cant tell if the error would induce your problem. Martin can you send me a copy too so I can check it against the basic 6 speed dat I keep on my files. I have so many different dats now it is hard to keep track of them all. For some reason, the delay slip overide setting was set to 3276% on the file I sent to Kevin. Quote Link to comment Share on other sites More sharing options...
Kevin Huntley Posted October 24, 2002 Author Share Posted October 24, 2002 Hi Phil / Martin, Thanks for the DAT files I will give them a go at 2 O' clock today and let you Know if that sorts out the problem. Phil:- I have compared both your orginal DAT file you sent and Martins on my PC and both delay slip overides are set to 3276%, so this may not be the problem. Is it possible that the launch control is not dis-engaging! As that what it feels like. I can put my foot to the floor and it just keeps missing at about 4000 rpm in all gears. I did not notice this happening before I loaded up the DAT file though. Cheers Quote Link to comment Share on other sites More sharing options...
Terminator Posted October 24, 2002 Share Posted October 24, 2002 When you get the laptop connected check the rpm trace on the monitor funtcion matches your rev couinter. If you did not have the problem before loading the new dat I suspect the 3***% figure may have something to do with it, as the book says this figure is set at 0% as stock. I have other 6 speed files that have the 0% settings I have sent you one of these as well. Quote Link to comment Share on other sites More sharing options...
Doughie Posted October 24, 2002 Share Posted October 24, 2002 Kevin 1) At standstill, in neutral, will the engine rev above 4000rpm? If not, then i suspect that it's something to do with launch control. The factory rev limit for launch control is about 4000rpm. Maybe the "little green button" is jammed on ? If the engine WILL rev freely when stationary, then i suspect that you may have got either the front or rear wheel sizes dramatically wrong in the DAT file. Or, perhaps, it is the 3276% thing as noted above. There is a "straight line slip over-ride" field that allows you to state how much additional slip (over and above the slip level dialled-in) you want when the car is going straight.

Graham Rudd Posted October 24, 2002 Share Posted October 24, 2002 Without wanting to get all geeky, I find it strangely coincidental that 3276 is exactly what 5% would be in a 16 bit fixed point representation (which is what the RL unit uses). Its as if whatever you're using to view the config doesn't realise that the slip value should be represented as a percentage and is showing the raw data instead.

Kevin Huntley Posted October 24, 2002 Author Share Posted October 24, 2002 Hello chaps, just got back from the mechanics and we still have not sorted the problem. It looks as though the revs measured on the laptop while in monitoring mode do not match what is shown on the Tacho. I tried uploading a couple of DAT files and it did not seam to make a diiference, However I did change the launch settings ( raising them to 5000 RPM) and when I test drove the car round the block the problem of the engine cutting out came in at 2500 RPM instead of 4000 RPM, don't know if this has any bearing on it though. I am taking it back on Saturday to have another go as I think it could have something to do with the wire that is monitoring the revs from the ECU. Anyone got ideas on what I should do to solve the problem? Thanks Quote Link to comment Share on other sites More sharing options...

There is more than one wire on the ECU that you can take the REV signal from, get your mechanic to move this wire. Sorry don't know the pin numbers off-hand.

Kevin Huntley Posted October 24, 2002 Author Share Posted October 24, 2002 Hi Martin, the auto electrition followed the pin diagram provided by Racelogic for the UK spec car, is that wrong? Cheers Quote Link to comment Share on other sites More sharing options...

Cheers Don't know because i've never seen it. If you grab the ECU diagrams from MKIV.com he should be able to see the various pick up points for the Rev signal. Anybody know the pin numbers off hand ? Quote Link to comment Share on other sites More sharing options...
