  2. air fuel ratio

    Tuning & Engine Management
    Hey guys... Just want to clarify something... The a/f ratio of the wrx is being maintained at around 14.7 by the stock ecu... So, does that mean even as rpm rises, the a/f ratio is maintained at that level? Or does it get richer as rpm increases??? Thanks!
  3. What's the stock boost level for our cars?
