KFLBTS lambda is limited by
- LATRO - Upper limit lambda target for exhaust gas temperature control
- 018ch ecu - 0X1D11E (16BIT LOHI)
- offset: x*0.000244140625

Set LATRO LAMLGMKT/LAMLGMTM high enough
BTS fueling should be able to request lambda>1
Add ignition timing for the areas you run lean:
- More advance to get lean mixtures to spark.
- Lean mixtures burn slower
E85 NOx emissions are lowest at very lean mixtures ~20:1, requiring ~50* BTDC at cruise on a 1.8T
