trinitom Posted October 31, 2009 Share Posted October 31, 2009 the only thing i don't like on the supra is the very light power steering feel when driving, i was thinking in get a switch to turn off the power steering when driving, and turn it on for parking maneuvers. is this been done? can this damage something? Thanks. Link to comment Share on other sites More sharing options...
Rob Posted October 31, 2009 Share Posted October 31, 2009 Even on roundabouts at low speed? Do you have massive arms or something? Just get used to it, power steering is the future. Link to comment Share on other sites More sharing options...

Depends on what speed you are driving, if you go on roundabouts at 5 mlh it could be dificult. Did you ever drive a none pw steering car? Link to comment Share on other sites More sharing options...
dr_jekyll Posted October 31, 2009 Share Posted October 31, 2009 supras have hydraulic p/s so a switch is not an option. the only way to do it properly is to replace the whole ps rack with a non power rack , but im not sure they made one to fit the supe Link to comment Share on other sites More sharing options...
Chiefgroover Posted October 31, 2009 Share Posted October 31, 2009 You could reset the front caster to 5.5 and set the toe to zero, which will make the steering feel quite a bit heavier. Link to comment Share on other sites More sharing options...

Are running in that setup? and will that have drastic changes on handling? Thanks. Link to comment Share on other sites More sharing options...
4packet Posted October 31, 2009 Share Posted October 31, 2009 It's a speed sensitive rack. Just pull the plug off the top of the rack near the column. That leaves it in fast (light assist) mode. Also worth checking what speed signal the ECM is receiving. If it's receiving a 5/8ths signal (mph) then it over assists. Mine felt much better when I sorted this.

Branners Posted October 31, 2009 Share Posted October 31, 2009 In the early days of speed converters this used to come up a lot. The steering is speed sensitive and so can become over light if the speed conversion is done wrong. Try unplugging the speedo converter and see if that helps the steering much.

SupraGirlie Posted October 31, 2009 Share Posted October 31, 2009 Mine doesn't feel that light at all. Maybe it's something to do with my 19" wheels? Link to comment Share on other sites More sharing options...
Branners Posted October 31, 2009 Share Posted October 31, 2009 i think the speed converter is well installed, it works as it should! but for me is to light compared to other cars, thanks anyway people. unplug it and try the steering again. The converter may be well installed but could be feeding the power steering the wrong speed figure. Got to be worth a try. Link to comment Share on other sites More sharing options...
Rich8v Posted October 31, 2009 Share Posted October 31, 2009 When my engine died and i was towed home about 10 miles with no assisted steering, I didnt find it too bad. I understand where your coming from, I find the steering too light above 50. I think you would regret binning the power steering althgether though unless your supra is a weekend/track car.

Errr no thats not what I wrote. It leaves the ps in its default mode which is lightly assisted as if the car is being driven at motorway speed. Without ps I think you would struggle to drive the Supra safely. I personally think you should just get used to it as the speed sensitive rack isn't that bad. I've driven mine in the default mode above and it feels OK until you need to throw a quick arm of opposite lock on and then you're going to struggle.

trinitom Posted October 31, 2009 Author Share Posted October 31, 2009 thanks for the help people, i will try what Branners and 4packet suggested and see if there's any difference. thanks again! Link to comment Share on other sites More sharing options...

4packet Posted November 2, 2009 Share Posted November 2, 2009 Drastically better. How do you get any sort of negatve camber on the front with that level of caster though? Link to comment Share on other sites More sharing options...
Scott Posted December 7, 2009 Share Posted December 7, 2009 How do you get any sort of negatve camber on the front with that level of caster though? It's a wind up Sorry to bump this thread, I'm guessing the answer was gotten. I'm having the exact opposite problem. Since some work has been done on my car my steering has became very heavy. The mechanic suggested that he possibly left the electrical connection (speed sensor) for the pump unconnected. Is it easy enough to get to without removing anything? Got my car in work today and even though its too dark just now I fancy getting it plugged in before heading home, if I can. Cheers Link to comment Share on other sites More sharing options...
4packet Posted December 7, 2009 Share Posted December 7, 2009 (edited) Yep its relatively easy. You should be able to see the plug next to where the steering column meets the rack. Access from the top. I'm not sure if there is a connection to the pump, I've only got experience with the connection to the rack.

bodilx6 Posted December 7, 2009 Share Posted December 7, 2009 Yeah, where is that speed sensor plugged in? I would very much like to try it on light assist. Anybody got a pic? Also worth checking what speed signal the ECM is receiving. If it's receiving a 5/8ths signal (mph) then it over assists. Mine felt much better when I sorted this. How do I check for this? My car is a j-spec, but running in DK so no mph/km fiddleings done. But my active spoiler comes down at aprox 90mph and goes up again at rougly 75mph, and I think this might be related to a more or less homemade SLD I got installed at some point.

Are you sure it can be accessed from there without removing anything? Thanks Link to comment Share on other sites More sharing options...
4packet Posted December 7, 2009 Share Posted December 7, 2009 I have an Apexi air filter and not sure if a stock air box would cause any grief. It's just by the chassis leg. 30 second job. Link to comment Share on other sites More sharing options...

bodilx6 Posted December 7, 2009 Share Posted December 7, 2009 Scott, could you do a pic if you find it? I'm a bit confused about specific wire we are talking about unhooking... Link to comment Share on other sites More sharing options...

There is only one electrical connection to the rack and it sits in the above described location. You really can't fail. Link to comment Share on other sites More sharing options...
