On a 997.1 you pick up an extra mode (3 total) and have access to all of the variables for tuning your own maps. Transformed the car in terms of feel and ride comfort, even on the stiffest "race" setting.

Cheers

You have one of the old ones. They have since made them all 2 mode boxes again.

It was a huge effort and breakthrough for us to establish this interface. We feel the effort was totally worth it to have factory level mode switch protocol. Not that there was anything wrong with the previous 3 modes(except for some who didn't care for the blinking LED) but looking at it now from where we are today it seem more "grassroots racing" like, which is where we started the company from. As our DSC company matures we feel that our products should evolve as well in refinement.

The difference- The 3 mode firmware started out as the engineers version which made the product development less time consuming to have an extra mode to test when track time is limited. At the time we didn't have the instrument interface capability so we could have actually made 4 modes, or 10 modes, or 20 modes if we had some way to indicate the modes besides watching the LED flash 10 or 20 times. The Engineers liked the 3 modes since they thought watching the LED flash 3x was manageable. We continued to offer the 3 modes until we established the instrument cluster display interface. As far as new DSC products go, the 3-mode version with blinking LED is outdated. The 2-mode version with factory mode switching protocol is current and is our proudly featured product. The new "Normal Mode"(softer mode) is same as the old mode 1. The new "Sport" is the old mode 2 and 3 merged. Keep in mind the modes are fully active and dynamic, which means the harder you brake, corner, and accelerate, the stiffer the car becomes.
