I believe ASC primarily operates through the use of a secondary throttle body just before (after?) the primary one. AFAIK, there is a solenoid that operates a butterfly valve, effectively cutting airflow to the engine when wheelspin is detected. I've heard that removing the TB altogether can give quite an increase in throttle response, as the opening in the ASC throttle body is substantially smaller than the primary one. (don't quote me on any of this, my car doesn't even have ASC) don't know much about the brake activity... Fraser __________________ -'95 ti - Stock. - '85 eta - some stuff. |
