Ned Posted July 28, 2011 Author Share Posted July 28, 2011 Has traction control but can turn that off (and i did turn that off) Quote Link to comment Share on other sites More sharing options...
felixx Posted July 28, 2011 Share Posted July 28, 2011 my parents neighbour brought one of these new, he still has it I think. It did have some get up and go when he brought it. He took me for a ride in it. He was a 60+ year old chinese bloke when it was new so he didnt do skids, but it seemed capable of it. Maybe just be content with power slides. BTW I am impressed with your ability to fix the CD player and your ambition to get the car phone working too! Quote Link to comment Share on other sites More sharing options...
lou Posted July 28, 2011 Share Posted July 28, 2011 Something is wrong for sure. Mine steps out on its own with traction control off and can wip it sideways with it on easily enough too. Cant be the computer surely as my later model will smoke up no worries. Quote Link to comment Share on other sites More sharing options...
sheepers Posted July 28, 2011 Share Posted July 28, 2011 replace the ECU temp sensor (its the green one out of the three) to sort out your fuel usage woes. and as for skids, mines a fly by wire VVTi model and it will lay some serious 1's with the traction control off. roll backs (very gently) will get you smoking, if not then i dunno. install supercharger?

Alistair Posted July 28, 2011 Share Posted July 28, 2011 I am yet to see a manual LS400. Would be badass/just shift kit the A340 and T70 it. Quote Link to comment Share on other sites More sharing options...
johnnyfive Posted July 28, 2011 Share Posted July 28, 2011 Whatabout swing an O then fot on brake to hold it stationary? Was my next plan Post pics/video of what ensues please. Quote Link to comment Share on other sites More sharing options...
Simon Posted July 28, 2011 Share Posted July 28, 2011 Si's one was ripping up 3rd with ease at the tui. Sheepers is most probably onto something with the temp sensor. If the ECU thinks the motor is cold it will pull the power back while enriching it. Quote Link to comment Share on other sites More sharing options...
lou Posted July 28, 2011 Share Posted July 28, 2011 Is the temp sensor something that needs to be replaced frequently? I can never be bothered working out the gas consumption of my cars but mine doesnt seem to do too bad. I just take it to full on a weekly basis.

Ned Posted July 28, 2011 Author Share Posted July 28, 2011 Cheers dude I did a compression test tonight with Cam at his shed. Was all around 210 give or take 5 for 6 out of 8. One was 195 or so and one was 220 so good enough. Temp thing sounds like a good place to start. Will have a look to see if i can see what sheepers is on about/go see him and get him to point it out to me. Also going to do spark plugs tomorrow as they looked like they could do with replacing for an extra 1000 milliHP haha. Got some glue to put the window winder switch covery things back on and some paint to paint the window wipers this weekend. Since the keyless entry on the key (did i mention this?) is not keen to work properly and a new one is $650, i have decided to make my own. Have ordered a key fob with 5 buttons with an AVR micro controller and a Nordic nRF24L01+ RF chip on it (same as on my GPS lap timer) and will make my own remote thingy. Am currently thinking of shit it could so. Current list; -Lock/Arm -unlock/disarm -windows down -windows up -remote start and possibly act as a stop button as well? Thats 5 buttons anyway. Could possibly/probably do lock/unlock on 1 button and windows up/down on one as well which would free up two more. One for boot popper and will have 1 spare for god knows what... filler cap popper? Any ideas? Quote Link to comment Share on other sites More sharing options...

lou Posted July 28, 2011 Share Posted July 28, 2011 Theres some good info on club lexus regarding these cars. All the hidden features and stuff as well as schematics for the sound systems and a full manual including wireing diagrams. Give me a sec and I'll find it for you. Edit: here it is http://www.clublexus.com/forums/ls400/4 ... hread.html In the service manuals link, youll have to go to the end of the thread and find the site that its on. Its hosted somewhere and they use a comunal log in to access it. Quote Link to comment Share on other sites More sharing options...
Ned Posted July 28, 2011 Author Share Posted July 28, 2011 <3 u! edit; had a read and will do this in the weekend! My speedo plays up every so often (read once) but the fuel guage isn't too happy with me so will replace a few capsl ike mentioned here and see how it goes then Wonder how much different it is for RHD vs LHD Quote Link to comment Share on other sites More sharing options...
lou Posted July 28, 2011 Share Posted July 28, 2011 Club lexus is a pretty good site to browse through. Especialy the 'post your car' topics. But I wouldnt bother joining up. Its not much of a close knit community and questions tend to be unanswered. Quote Link to comment Share on other sites More sharing options...

Any ideas? My wife's airtrek does windows up etc.. and also a long press on the lock button will fold the mirrors away... (fuck knows why) Boot popper sounds good if it's already electric.

Ned Posted July 29, 2011 Author Share Posted July 29, 2011 Replaced temp sensor today and all spark plugs... still no b-outs Attempted to re-set ECU (like someone on the Lexus forums suggested) by disconnecting the negative of the battery for a few minutes and still no go. Will try resetting ECU again by unplugging battery for a few hours and see how that goes.. Quote Link to comment Share on other sites More sharing options...
UTERUS Posted July 29, 2011 Share Posted July 29, 2011 On my car, it was really sluggish because the fuel pump ecu/resistor gaylord was all on the piss and would never switch to full voltage properly. I have no idea If the UCFXX stz has a similar system but from memory you can bypass it by mashing a wire across E1 and TE1 in the diagnostigs port in the engine bay. If that doesn't work, see if unplugging the AFM makes any difference. Quote Link to comment Share on other sites More sharing options...
Ned Posted July 29, 2011 Author Share Posted July 29, 2011 What would/should/coule happen if i do unplug the AFM? Quote Link to comment Share on other sites More sharing options...
