in the primary maps and properly setup the secondary and 5th gear fuel map in the event something isn't right. If it knocks, it will kick into safety mode and have appropriate maps. For those with boost jets, its not a big deal because boost will drop, but guys with boost controllers need additional protection as boost will not drop when a problem is detected. With my mappings, power will drop because fuel increases and timing retards and the driver will notice a significant drop in power and know something is wrong. JWT's programming does not do this.
