A Wide Band O2 Sensor (WBO2) is an excellent tool for measuring what the AE air fuel ratios (AFR's) are. Typically the BLM's are locked at 128 when AE is active, which doesn't really help with tuning AE. What are your AFR's when AE is active? Typically, butt dyno's are awesome tools too, but not as accurate as AFR's.
