Working on a basemap for a Turbo RR and I'm looking for some information. I'm working on just fueling adjustments and I'm logging commanded Lambda, along with monitoring actual AFR with my Dyno's wideband and seeing a very lean condition on the stock map that commands a 1.00 lambda - even at full boost - up until around 50mph/7800rpm. Keep in mind this is a 100% stock file (minus the Ext Datastream OS mod). After that, Desired falls to 0.73 and the wideband reports safe, mid 11.x afr.
Im looking for a setting/map(s) that determine what the desired lambda is during normal operation and why it is changing at that point.
