I work for a distributor of a different EFI system, one that also offers table switching. I don't really think much of table switching between power and economy maps, however, as a well optimized fuel and spark map will provide both. You don't do much racing in the cells most heavily used for driving. Table switching does have a few good uses:
1. If you have one table for race gas that allows a more aggressive advance curve and one for pump gas. (If your engine's advance is limited by detonation. Some aren't.)
2. A separate map for when your engine is on nitrous.
But usually you switch between economy and racing with your right foot. I'd say less than 1% of our customers use table switching for much of anything.
