I found this and thought some here would like to know a bit more on how the magna steer system works. note: there is no mention of how the traction control systems intergrate with this system when a skid or spinout is detected.

Variable Effort Steering Description
The variable assist magnetic steering system (Magna Steer) varies the driver effort required to steer the vehicle as speed changes. At low speeds, the system requires minimum steering effort for easy turning and parking maneuvers. Steering effort is increased at higher speeds in order to provide the driver with firmer steering (road feel) and directional stability. The EBCM controls a bi-directional magnetic rotary solenoid. The solenoid is located in the steering gear. The EBCM varies the steering assist by adjusting the current flow through the solenoid. The solenoid adjusts the amount of power steering assist in order to achieve a given level of driver effort to turn the vehicle.

Magna Steer accomplishes this by adding or subtracting torque on the rotary input shaft to the power rack and pinion. The amount of steering assist is dependent upon vehicle speed. As the vehicle speed increases, the following actions occur:

• The steering assist decreases.
• The driver effort increases.

As the vehicle speed decreases, the following actions occur:

• The steering assist increases.
• The driver effort decreases.

The scan tool can be used to adjust the amount of steering assist if the customer requests. The steering assist has 3 settings: (Tech2 scanner)

• Factory calibration
• More firm
• Less firm

Variable Effort Steering


it says i have that......might not be the same for a 94..........but i don't think it does anything

Does the steering feel stiffer going into a high speed corner? Mine does.

hhhhhhhhhmmmmmmmmmm i doubt it..........i just thought variable effort would be smoother

we have a 96 at our house that is capable of whippin' doughnuts with a pinky movement (exaggeration obviously, but its way easy to steer than mine)

Found some more.
The purpose of the Delco Bosch 5.3 Antilock Brake System (ABS) is to minimize wheel slip during heavy braking. The Delco Bosch 5.3 performs this function by monitoring the speed of each wheel and controlling the brake fluid pressure to each wheel independently during a braking event. This allows the driver to retain directional stability and better steering capability.

The optional Traction Control System (TCS), option code NW9, also monitors rear wheel speeds and compares the rear wheel speeds to the speed of the front wheel speeds. If excessive front wheel speed is detected in either front wheels the TCS will be activated. The TCS uses the following to improved traction and vehicle stability:

• Engine fuel control
• Engine timing control
• Front brake intervention

The optional Vehicle Stability Enhancement System (VSES) , option code JL4, monitors wheel speeds, lateral acceleration, and steering sensor inputs to determine a desired yaw rate. This desired yaw rate is compared to the actual yaw rate. The VSES tries to bring the values into agreement by selectively applying the front brakes.

So who'* going to go and set there'* up to the "More firm" setting and let us all know the difference. :?:


Yes the stability control only works the front brakes....and worse yet, you can't turn it off. That was a disappointment when I purchased it. [/quote]

Well as soon as I read this I got to thinking. I need to borrow the SSEi and take it for a few drives before we sell it anyways, I may as well take it to school and put the tech 2 on it and make a few "adjustments." If my mom will allow, I will bring the SSEi to school and change the setting, then drive the car, and see the difference, then of course change the setting back when I'm done.

I wonder if you can do the same thing on the GP'*??? I know our GTP has the magnasteer...so I would think it would be the same.

P-Dad good stuff there. Sounds very simular to the Aurora electronic controll good traction stuff.


Going in for an oil change at the dealer soon, I'll ask them to do if there not busy. Might as well program a gretting message. Need to decide on somthing.

I was taking some pictures on an abanded road today and I noticed a whole bunch of burnout marks all down the street I stoped on. After couple of pics a laid a few marks myself thinking about my traction and how'* it hooking up, and proper launch RPM'*.

There was a little wet spot that I rolled up too, like a burnout box and I attempted twice to set the e-brake and try to get the front wheels smoking for a second or two. The car did not want to do this, the ebrake held for only wheel spin to say 10-15mph'ish and the ebrake would disengage it'self according to the instrument panel and HUD, even though the lever was still "engaged". Interesting I thought, and sure enough, once the you jump on the gas with the parking break, it de-actives.

I bet this can also be over rided by pulling the front wheel sensors at the track like Scott does.

I'll second Taylor, sounds exactly like my car

I'm beginning to think the guts behind the now dead 95-99 has reincarnated into the 2000+ Bonnies

This sounds like something that could be turned off with a custom pcm? Of course I would still want it activated with the switch when needed
