Back from the dead!
Hey Fellas.
I know this thread went dead last year, but I figured I should check and see if there was anything new with regards to this?
Some notes on the Stability Control System. It takes inputs from all sensors, and basically calculates from steering angle, and vehicle speed, and decides if the lateral forces / polar moment are correct and match up. It sounds quite simply that there is an upper threshold that has been added, (Toyota style!) that kicks in when you get outside of some pre-determined envelope. My experience with these types of systems strongly suggests that body roll is a minimal factor, and most likely absolute lateral G's is the first algorithm, and following that it intervenes in a secondary fashion due to loss of grip. Unfortunately, this type of system is hard to fool, as it functions as "envelope protection".
Some potential solutions...... Move the sensor FORWARD on the chassis, and to a lesser extent, lower. Although this will dampen it's intervention, it won't solve it. Reducing the load on the sensor or filtering it's output is the only full solution. Tilting it forward should also allow for more acceleration, as I would bet this system uses longitudinal acceleration, unlike most other stability control systems.
These are just experienced guesses, but I will be looking for answers too soon.
Anyone who has ridden a snowmobile at 9/10th plus, would likely have a pretty good idea how to handle the unique reactions of a vehicle laid out like the Spyder is. This "lawn dart" crap is really tiresome, but the fact is, a skid is the prelude to an accident for some, a scary moment for others and the start of fun for others still.
And to the chicken little's,....... "A man has to know his limitations". :thumbup:
