1. So there a basically 3 main maps stored in the ECU: base, aggressive, and reserved. With a normal ECU reset, the ECU switches to the original base map w/ a multiplier of 8. The multiplier is used to take a "porportion" of the aggressive or reserved map and add it to the base map to give it an overall more aggressive calculation. The "Vishnu Reset" actually fools the ECU and tries to set the multiplier to 16 or as close as possible so the ECU will take a "larger" proportion of the aggressive map sooner. The ECU also inlcudes a table where past knock has occurred and applies less timing in those certain areas. Am I correct now?

2. Does the "aggressive" map include more timing and less fuel or just more timing?

3. How many cycles should I do of the 2500-4000rpm @ 2-5psi for 5-10 sec runs to finalize the "Vishnu Reset?"
