ccwade Posted May 22, 2011 Share Posted May 22, 2011 Hello and thanks for helping. I live in the US and have a 98 auto TT, when i get on the accelerator sometimes only the right tire spins and sometimes the left tire spins. Is there a way i can fix the traction control or something else to force both tires to always spin together? I am use to old school american cars with limited slip and positive trac rear ends. Not familiar with supra setups. tks d.wade Link to comment Share on other sites More sharing options...
Chris Wilson Posted May 22, 2011 Share Posted May 22, 2011 The traction control merely moderates engine torque output via the ecu. To give any meaningful traction via mechanical means, look to a TRD LSD diff centre section, or if the budget allows, an OS Giken LSD centre section, which, off the shelf, is as good as they get. I can supply these, they are REALLY good LSD's with really trick technology that can be user tweaked. I am in the UK, so carriage could be costly, but I *AM* knowledgeable on suspension and traction.

ccwade Posted May 22, 2011 Author Share Posted May 22, 2011 tks chris, i have pulled up osgiken web page and looked at the lsd center section you mentioned. i was hoping there was some way to make my supra positive trac by enabling or disabling something in the traction system or electronics area.

Chris Wilson Posted May 22, 2011 Share Posted May 22, 2011 That's totally impossible, the TRAC control is purely electronic and affects a secondary throttle body butterfly. It has nothing to do with the rear differential. Link to comment Share on other sites More sharing options...
ccwade Posted May 22, 2011 Author Share Posted May 22, 2011 ok, can you or someone briefly explain how the supra's differential works? and are they all the same for gen 4 supra's. Link to comment Share on other sites More sharing options...
Chris Wilson Posted May 23, 2011 Share Posted May 23, 2011 Some are an open differential, with no locking at all, some have a Torsen type LSD, Google differentials and it will explain both open and Torsen types with diagrams of the power flow. The chassis plate shows what type of diff was originally fitted under the axle code. Link to comment Share on other sites More sharing options...
Thorin Posted May 23, 2011 Share Posted May 23, 2011 You have an auto so more than likely it's an open diff. Either try and get a stock Torsen diff or the TRD or OS Giken ones Chris mentions Link to comment Share on other sites More sharing options...
