Steve W Posted July 20, 2002 Share Posted July 20, 2002 Thinking quite a bit ahead..... When you all put the RLTC on, do you remove the TRAC butterfly or is it part of the RLTC (I would think not, but, didn't know for sure) Just noticed the photos of 'removing' it on mkIV.com and am thinking that that would be a good idea to stop the 'power-cut' when TRAC comes on ? ? Any disadvantages ? Would the brakes still 'slam on', or would the fact that the power can't be cut make it feel less sudden ? {only curious..........for now !} If I 'pull-the-fuse' I know the TRAC OFF light will always be on (but thats probably good idea anyway) any reason why you shouldn't leave the fuse out..... I thought someone said (somewhere) that it could damage something ? ? AND, is it right that pulling the TRAC fuse in a UK disables the limiter (or is that POOH ?) BUT, it doesn't disable it in my Jap' ? ? Quote Link to comment Share on other sites More sharing options...
Matt Harwood Posted July 20, 2002 Share Posted July 20, 2002 On a J-spec car the TC only shuts the butterfly. You don't "need" to remove it but I have. Mainly so that I didn't need to remember to switch it off and I didn't want to just pull the fuse. The UK spec also applies braking to the rear wheels (handbrake turn anyone! ) And that's one less restriction in the intake side... If you get an American butterfly removal kit it might add 50 bhp!!! Edited after reading your post again... I don't know for sure but I believe the fuse also controls something to do with an auto gearbox. I think it gives smoother changes or something... And yes you do loose the 155 limiter on a UK car but not the J-spec. Wait around a bit and I'm sure someone can confirm/explane this better or just tell me I'm wrong Quote Link to comment Share on other sites More sharing options...

GavinL Posted July 20, 2002 Share Posted July 20, 2002 the rear wheel braking function doesn't exist on the j-spec car so that's not an issue. Quote Link to comment Share on other sites More sharing options...

Adam Kindness Posted July 20, 2002 Share Posted July 20, 2002 Removing the trac fuse on a jspec auto speeds up the changes (not as smooth) and disables MANU mode... OD still works tho the limiter is still there Quote Link to comment Share on other sites More sharing options...
Syed Shah Posted July 20, 2002 Share Posted July 20, 2002 Isn't there a worry of it damaging the auto gearbox? I think that it has been linked to quicker wearing of the auto, so removing the trac fuse on these could be a bit risky. Fine on a manual though.

Steve Cargill Posted July 21, 2002 Share Posted July 21, 2002 I think it gives the trac butterfly a quick flick when the auto box changes so as to reduce the torque and give a smoother change. Quote Link to comment Share on other sites More sharing options...
Terminator Posted July 21, 2002 Share Posted July 21, 2002 Originally posted by Steve Cargill I think it gives the trac butterfly a quick flick when the auto box changes so as to reduce the torque and give a smoother change. I think the manu mode overrides this function, so Toyota thought it was OK. The owners manual advises against keeping the throttle pressed while manu shifting, which suggests that in auto mode something else prevents full torque through the box while changing. However the MKIV auto box is very strong. Quote Link to comment Share on other sites More sharing options...
