Yeah, in the future, you can ask all the question regarding Speed Passion at the "Speed Passion" thread here in Rctech....most of the time, you can find your answer there before even asking.
To answer your question....indoor carpet (or wood over Europe)...I would use 091110 software, AMTS 22.50, DRRS 7.....final drive @ 4.5. Motor timing at stock position (5* or middle).
Give that a shot...and check motor temperature.
