DSC's dirty little secret

The RX-8 has DSC enabled by default.

Mazda put in a disable button that you can depress for 2 seconds to disable some of DSC's features.

What isn't in the manual is a secret mode that can be activated by holding down on DSC even longer than 2 seconds. You'll know when it activates because an error light will turn on in your dash. That's Mazda's way of avoiding lawyers - DSC "malfunctioned"

What this "DSC error" does is remove ALL DSC functionality.

Please be warned that according to the Service Highlights manual, code C1093 (DSC OFF switch system) is logged. The DSC hydraulic unit/control module has a non-volatile memory that cannot be cleared even if the cars battery is removed.


Rumor is that disabling DSC will yield better gas mileage. There has been no concrete proof of this, and more often than not, users who believe this end to report later that they wrapped their car around a tree. Go figure.

By plugging in a Cobb Accessport, I have managed to figure out how to drive my car to get the best fuel mileage. The sweet spot to cruise is between 2250rpm to 3000rpm

My Rx8 does not have a DSC switch installed, will the wiring be there if I were to order a switch, so I can shut off the DSC? If not, how can I shut off the DSC without disabling the ABS (eg. Pulling the fuse). I have installed factory fog lights, and the wiring was already there, the heated seats wiring is already there, I wanted to know about this. I have an automatic and starting from the line is sluggish, after 4000 rpms the car moves.
