Want bigger biceps? Disconnect your PS ECU
Thanks to devildog who confirmed it's safe to disconnect the power steering ECU, I will be doing this soon just to mess around with it for a while.
I'll post pics of where it's located. and report on how big my arm muscles get. j/k!!

sorry to bring up old post...
I am an SC owner and was wondering if I could do this as well. Is it safe to do this - drive withou the p/s ecu? Has anyone else done this? Is it even worth it? Just want to try to get a "sportier" feel to the wheel when driving at higher speeds. thanks

OK since this is getting a revival I'll explain more..
The PS ECU box is located under the steering column. It's a white box that is labeled "POWR STEERING ECU"
You can reach around if you know where it's at and unplug it, but first timers should find it by unscrewing the 3-4 screws that hold that lower panel and pull it down to see the ECU.
This is my conclusion on what unplugging it does. Basically there is a number value assigned referencing how fast you are traveling. When you are going really fast the ECU may receive a signal of let's say '5' = this is the stiffest setting. When the ECU is unplugged it's reset to the stiffest value.
You still have the power of the rack and pinion on unless you disconnect the power by the P/S pump on the rack and pinion. If you unplugged this driving the car would be really like having NO p/s at all and would be extremely difficult. Ever driven a non p/s car? It' pretty tough until you start driving and get used to it.
My recommendation is to try driving it for a day or two and see how it feels. The thing I did notice was that when you plug it back in, taking corners is 100% easier on the arms and you can do 'deeper' turns left or right because the steering wheel turns a farther distance with less resistance.

Onehott,
I am not looking for bigger arms What I am looking for and this "mod" may help is that on other sports cars (porsche, BMW,) the power steering is firmer to begin with, helps in feeling the road, better feel, heavier to have "better" control at higher speeds. If you drive a porsche/BMW or other sports car you will know what I mean. There is power steering but on our luxury lexus its almost too easy to turn, on the sports cars its still easy to turn but you can feel the turn more because the steering is heavier - this is what I am looking for.
