Dom,
The last iteration of the tune you did for me went a long way to mitigate the coasting to tip-in hesitation/bogging and intermittent stalling. The stalling has not reoccurred and the hesitation is much less pronounced and less often. For this last iteration I know you increased the AE another 8%.
Since you have been teaching me and I have been trying to teach myself the tuning process through extensive reading on the subject, as you know I bought all the hardware to evaluate and make changes myself.
In the last few days I have made the following changes to that last tune. I smoothed both the port throttle open VE tables. (My secondaries have been eliminated so the engine runs primarily off these tables) I did that one column and row a time. I utilized the “smoothing” program in TunerPro. In that process I found that the 2000rpm row that appears on both tables significantly didn’t match. I have read that it is important they match. So I matched the row for both tables.
I drove the car yesterday and the change is remarkable, hesitation/bogging are gone and there was no stalling, not even an rpm drop. Surprisingly the engine has never run as smoothly as it did yesterday. Previously there has been a hard to describe harshness and occasional jerkiness to it. Minor but noticeable. That was gone yesterday.
That said, one 40min drive isn’t the last word how the tune performs. I plan to data log it today or tomorrow weather permitting. I’m anxious to see where this takes us...
