so i played with some stuff tonight, looks like the PWM should have been inverted because it actually stays running now. i have attached a log of two runs.
1. open loop 2. closed loop.
for open loop, rpm surges for about one min before settling around 1k .Once the wideband kicks on, it runs very lean up to ~16-17 and oscillates gradually settling down to about 14.
For closed loop, i didnt change any default settings, but immediately runs a touch better. RPM still hunts but the oscillation range is much less.
One variable that stick out to me is the PWM Idle duty. Looks like once the idle duty gets to 40% in open loop it settles down, and when in closed loop around 60s into the run, it immediately jumps to 40% and everything stabilizes as shown below.
One other question, to get my AFR's down to reasonable levels i had to bump my idle cells to high 60's/low 70s. It seems high compared to other tunes i have seen, makes me think something else is going on?
Thanks
