mawby Posted February 15, 2008 Share Posted February 15, 2008 1) What is the difference between the standard and tiptronic auto box - is it just the ECU that is different or is it a completely different box too? 2) Has anyone ever converted a standard auto into a tiptronic?

Pete Posted February 15, 2008 Share Posted February 15, 2008 I believe technically it's the same box but having seen pictures of them both before I seem to remember that the vvti one does have some extra gubbins on it? Quote Link to comment Share on other sites More sharing options...
SteveR Posted February 15, 2008 Share Posted February 15, 2008 Was the tiptronic only ever available on the vvti? Quote Link to comment Share on other sites More sharing options...
Pixelfill Posted February 15, 2008 Share Posted February 15, 2008 I don't know for sure, but if Tiptronic is only available on Facelift (read this as vvti), then the ECU and loom are different so can't be retro-fitted to a pre-facelift. Whether tiptronic can be retro-fitted to non-tiptronic facelift autos I don't know. Mike Quote Link to comment Share on other sites More sharing options...
Jake Posted February 15, 2008 Share Posted February 15, 2008 As far as I know it's the same gearbox. I like autos but I wouldn't have another Tip. It's a gimmick and doesn't work particularly well IMO. The upchanges are OK if a bit slow, but downchanges are impossible to do smoothly like you can do with a manual. And the way it it just ignores you if you try to change down if it thinks the revs will be too high in the lower gear if bloody annoying. The worst thing though is the fault MPH converted Tips all have which makes it change down to 3rd gear at WOT even if you're doing 150mph at the time.

I did look at using a megasquirter3 module which can control the autobox supposedly, but didn't really progressive it much further...could be an interesting idea.

JustGav Posted February 15, 2008 Share Posted February 15, 2008 You just run a delimeter then? Which one? Hmmm, truth be told, I'm not sure... I know there was one in the loom but I didn't look at the type, it worked so I left it. Quote Link to comment Share on other sites More sharing options...
garethr Posted February 16, 2008 Share Posted February 16, 2008 Suprastick apparently can do it.Not on a Mk4 (or Aristo) AFAIK. Doesn't work with boxes which have electronic line pressure control. Quote Link to comment Share on other sites More sharing options...

Link that to a display which shows the current gear you're in and you're starting to bring the Supra up-to-date with more modern auto's.

Hmmm, I shall dig out the notes that I have and speak to some people and lets see what can be done The paddles bit is dead easy as that is simply microswitches or perhaps an aftermarket steering boss which has them.

Pete Posted February 16, 2008 Share Posted February 16, 2008 I would love paddles. The position of the buttons is dire making it difficult when driving spiritedly to hold the wheel properly and change gear. Quote Link to comment Share on other sites More sharing options...

Pete : Moving to a paddle system if you already have vvti isn't a difficult thing to do as the wiring is already there. Quote Link to comment Share on other sites More sharing options...
Branners Posted February 16, 2008 Share Posted February 16, 2008 Racelogic used to do paddle shift conversions for most autos but said it just couldnt be done on the Supra. Times may have moved on though, that was about 7 years ago. JB Quote Link to comment Share on other sites More sharing options...
paul mac Posted February 16, 2008 Share Posted February 16, 2008 personally i dont really get all this flaping about with flappy paddles i have driven a VVTi with said flaps but after 10 minutes i got board with it and just left it in "D", my advise is go single and get a Boostlogic auto box with a high stall , you'll never mess with flaps again Quote Link to comment Share on other sites More sharing options...
dangerous brain Posted February 16, 2008 Share Posted February 16, 2008 You could do it with steering wheel mounted buttons easily enough. If I keep the auto box on mine I'll go with this option. 1 and 2 under my left thumb and 3 and 4 under my right. Only operates in manu mode.

I don't use manu mode often because I think the auto box in the Supra is far better at what it does than me but on the odd occasion I've tried it changing down gear has always resulted in the car jolting.

paul mac Posted March 3, 2008 Share Posted March 3, 2008 i think the main problem with "our" gearbox is it pre-dates all the new flappy paddle stuff which Jake eluded to earlier on, new generation performance autos are five and six speed to take advantage of the technology, the new boxs are designed right from the outset to have electronic shift at the touch of a button whereas our 30 year old 3 speed boxs were never really designed for downshifting in this way, i think if you enjoy manually shifting you really need a manual or mate a 6 speed auto merc box to the 2JZGTE (now theres an idea ) Quote Link to comment Share on other sites More sharing options...
