The section I copied was a copy of a post that Ross made in another thread...

There is no alternate spark maps as suck, just that both the High and Low Octane maps will work in the custom OS's when running MAFless (Speed Density), whereas with a stock OS running MAFless it would only use the Low Octane table. I'm sure you knew that already, but just for other peoples benefit

The Valet Mode/Two Step (Rev Limiter) tables are:
A0011 - To actually enable the function and requires that you wire a switch into a particular pin on the PCM
A0012 & A0013 - Speed limit for ETC or cable throttle controlled vehicles when in Valet Mode/Two Step
B3324 & B3325 - RPM upper and lower limits when in Valet Mode/Two Step

Cheers,
