I don't believe PSM limits or takes steering input away from you.

If the PSM system retards power, then weight could shift to the front causing the steering to feel heavier. Not sure I understand what your doing or under what road conditions to induce this feeling.

Is PSM 'limiting' the steering input? Or is this just physics?


You sound like you may be understeering.

Your lift is loading the front tires and then you are trying to input more steering. Tires can't handle both depending on speed that is. So car won't turn and steering gets heavy.

BTW... steering input does not give a little more oversteer.

Just 'physics' as Buckwheat describes. PSM reads your steering input to decide what you're trying to do and then aids that effort rather than defeating it.

You can only understeer a muscle car around so many corners before the symptoms are etched in memory. Boy, did a 350SS Camaro use up tires with the fronts sliding sideways while the rears spun futilely. You described the effect quite well. Although you omitted the Top Gear-style cloud of smoke, which admittedly is optional.

Last year, the startling new information for me was that a modern Porsche behaves that same way at first. It took me nearly three hours of track time to figure out why and how to get it cornering like we all know it wants to: like a race car with leather seats. Damn, I love this Carrera but I had to woo her like a shy vixen. (If you can picture that combination.)
