Fully utilizing the ability to integrate wideband O2 collection (or stock O2 collection) with the tuning table parameters reported by the ECU, Direct Link greatly reduces the users need to do cell by cell tuning calculations with a feature called Auto Mapping.
Auto Mapping increases the time that can be spent refining a tune while significantly decreasing the time of the tune as a whole.DIRECT LINK USER INTERFACE
