Awful lean stumble after coast
As an aside on noisy in-line pumps, I mounted mine using the circular rubber lined clamp fixed to the chassis using cotton reel type vibration mounts, down low so it doesn't have to suck and work hard [noise also sign of a blocked filter], can only just hear pump when priming.
I also had a flat [lean] spot on accelerating from standing start with 30003, ICU compensating by going rich, turned out I had a small leak at O2 sensor.
I am very curious to hear as well on the lean coasting condition, or if anyone else has found anything on this topic.
I believe DFCO should be fully disabled (set the enable temp to ~300, fuel cutoff Map to like 4, fuel return Map to like 6), and fuel pump PWM set to 100% with it's thresholds set to values I'm always meeting, but even so it goes full 20.6 AFR when I'm off the throttle in gear.
I have the 198 software as well, which I see a bunch of tip-out settings that I haven't messed with yet...
