XFI users or others familiar with the stock ECM's programming: What values are you using for XFI's ESC function, which has three values to enter :

1. Max. ESC Retard (*)
This is the maximum amount of timing retard allowed if the knock sensor is activated. Even if knock is still detected once this limit is reached, no more timing will be pulled out.
2. ESC Attack Rate (*)
This parameter defines the number of degrees to retard the timing every .1 second when the knock sensor is activated. In other words, this parameter is used to set how fast the timing will be pulled out when knock is detected. In the above form, with the attack rate set at 5, the timing would be lowered 5 degrees every .1 second until the knock sensor deactivated, or until the maximum ESC retard limit was reached.
3. ESC Decay Rate (*)
This parameter defines the number of degrees to remove the timing retard every .1 second after the knock sensor becomes inactive. In other words, after timing is pulled out due to knock detection, this parameter is used to set how fast the timing will be added back in. If the decay rate is set to 0.50 as above, the timing will come back in at .5 degree per .1 second (or 5 degrees per second) until the ESC retard has reached zero.
- Max ESC retard (in degrees)
