— Notes from the tuner
What we did.
BMW X4 with the B58 engine came in for a Stage 1 tune. However, we had to halt the tuning process due to knock detection issues. To touch on this there are numerous factors that can lead to knock occurrence, one of the most common causes we find is the use of incorrect fuel or insufficient octane levels.
