Yeah, if you get a weird AFR where you cannot hold the rpm at a particular TP, datalogging is the only way you're going to see it and fix it manually. If you see a weird trim show up repeatedly, you know there is a problem but it's hard to see the AFR it produces with how fast that cell gets passed through during a run. I tried it once and it seemed to improve but no way to know for sure without datalogging which I will be doing soon.
Autotune throws to many false numbers even trims AFR'S in spots you never been operating in !!!
I noticed I got a trim of 1 at 12000 rpm and my bike does not even go to 12000. Dj said that some vehicles have their own excell pump feature in the ECU. Many ATVs have this and when the excell pump kicks in, the injectors spray 10x as many squirts as normal. The PCV software reads rpm off of the injector pulse so when excell pupm is active, you get your actual rpm x 10. so a trim ends up at the highest rpm cell in your table. Other than that, IDT I've seen any trims where I have not been during a run....but I am only tuning one column at a time with all other AFRs zeroed.
So how 'bout this "throttle lift?" is that zero throttle with engine decelling? The term sounds like it might be the effect of the rpm rising while throttle is held steady but reading your whole post from yesterday, it looks like you were saying that Autotune thinks the throttle is still OPEN a while after the throttle has been sprung to 0%. And the false trims only show up in the fuel dump zone we tune in Neutral? So we shut the fuel dump zone off during road tuning to not get any false trims?
Why don't we get the same false trim effect while tuning in Neutral?
I have a couple hypothesis but I hate to presume.
