Ethanol blended fuels can decrease LSPI-knock ... but only if HIGH blends are used.  In this study, E20 and E30 actually increased the incidence and severity of LSPI-subsequent knock events.  E50 still has the propensity for more LSPI, with decreased propensity for resulting knock events.

If tuned:  Take note of the strategy code as you return to stock (including 3 bar MAP to 2 bar MAP) -> take car in & get it serviced -> check strategy code when you get car back -> have tuner update your tune if the strategy code has changed -> reload tune -> ENJOY!

It was interesting the graph of RPM vs Pressure and LSPI.  Basically you want the gear to shift lower the instant you floor it.  But using an SN PLUS oil should go a long way towards avoiding the LSPI.  Prevent a situation by avoiding things that contribute to it.
