We have to remember though that with piggy back systems we do not have complete control over the timing or the fuel for that matter. Richening up the mixture with the SAFC or MAFT may serve to decrease timing and richen the mixture, but in the end the ECU has final say based somewhat on what we tell it or how we fool it. Immediately and over time it will retard timing as it continues to see knock. It will change the fuel and timing maps to whatever it sees as best for the engine based not only on the MAS input that we have control of, but also on O2 sensor input and knock sensor input, which we don't have control of with a piggy back system.
