Justin Posted November 8, 2005 Share Posted November 8, 2005 I'm having trouble getting any help on this so I need to fit one myself. Good instuctions here http://www.utahracing.com/Tech/lockup/Lockup.htm Anybody know the exact type of relay I should buy to make up my own kit to wire into the OD button and solder to my ECU? Should it be a 12V 30Amp 5 pin relay like this http://www.demon-tweeks.co.uk/products/ProductDetail.asp?cls=MSPORT&pcode=LMA795 ? Thanks Justin Link to comment Share on other sites More sharing options...
LeeT Posted November 8, 2005 Share Posted November 8, 2005 i havent looked into this too much yet but there is a way to do this without using a relay. just a switch to earth iirc. im sure matt harwood or b'have would know Link to comment Share on other sites More sharing options...

b_have Posted November 9, 2005 Share Posted November 9, 2005 Hi Justin, been at the Tokyo motor show all week, so not been online. No need for a relay, just ground 14b to earth.I have mine wired to a push button on the steering wheel. Use it all the time to simulate upshifts.

veilsideTT Posted November 9, 2005 Share Posted November 9, 2005 i take it you use a push button that stays pushed in? i,e, keeps the wire to ground untill you push it again to unlock the TC? Scott Link to comment Share on other sites More sharing options...
LeeT Posted November 9, 2005 Share Posted November 9, 2005 i take it you use a push button that stays pushed in? i,e, keeps the wire to ground untill you push it again to unlock the TC? Scott im going to use the stock overdrive button Link to comment Share on other sites More sharing options...
veilsideTT Posted November 9, 2005 Share Posted November 9, 2005 what are you going to use for overdrive then? Link to comment Share on other sites More sharing options...
LeeT Posted November 9, 2005 Share Posted November 9, 2005 what are you going to use for overdrive then? i never use it but i'll put an extra switch in the dash somewhere though to replace it with. Link to comment Share on other sites More sharing options...
Justin Posted November 9, 2005 Author Share Posted November 9, 2005 im going to use the stock overdrive button Same here. I used to use the OD a fair bit but not since the TC was fitted. Link to comment Share on other sites More sharing options...
Pixelfill Posted November 10, 2005 Share Posted November 10, 2005 Forgive my ignorance guys, but can anyone explain what the purpose of this modification is. I'm guessing that it's to get better launches, but I'd appreciate the theory etc. Thanks guys Mike Link to comment Share on other sites More sharing options...

Any chance of a wiring diagram like the one in my link when you get back from Japan? When should you not use lockup? I've read some dodgy stories on Supra Forums.

LeeT Posted November 10, 2005 Share Posted November 10, 2005 What dodgy stories? im sure you could tell him when not to use the lock up? for instance if you are locked up when coming to a stop you will stall Link to comment Share on other sites More sharing options...
CJ Posted November 10, 2005 Share Posted November 10, 2005 im sure you could tell him when not to use the lock up? for instance if you are locked up when coming to a stop you will stall Yep..done that a few times and shat myself in the process Other than that, i dont know of any other occasions you should not use it. I use mine to chnge up if the g'box isnt doing it and to hold a gear on the motorway to stop the thing changing up and down. I also use it on A roads as going up hills makes the thing change down to rapidly. Link to comment Share on other sites More sharing options...
Justin Posted November 10, 2005 Author Share Posted November 10, 2005 What dodgy stories? Some guy blowing up his TC because he engaged lockup at the end of a 1/4 run or something like that? http://www.supraforums.com/forum/showthread.php?t=191513&highlight=torque+converter+lock+switch He starts..... "I have a built transmission but my converter is my weak point. I have had my PI triple disk fixed twice now, under warrantee. The clutches are fried in the lockup. Ip has been great to work with but the converter design has problems. ................................." Sorry for the silly questions but I haven't used this setup before so have to ask I don't mind admitting. Cheers for your help guys. Link to comment Share on other sites More sharing options...

Matt Harwood Posted November 13, 2005 Share Posted November 13, 2005 I've already asked both parties mate and no response I'm afraid. First time I've had any kind of chance to reply mate. I don't get much of a chance to get on here any more due to various different circumstances, but my work phone number is at the bottom of my signature and there's an answer phone on there if I can't answer. Have you sussed it yet? Personally, I'd do it with a relay, but it can be done by simply switching an earth onto the wire. Link to comment Share on other sites More sharing options...
