thats perfectly normal thats decel fuel shut off

the engine isn't lean on decel its off

Have you tried completely disabling DFSO in your tune to see if you still see what youre seeing?

Dfso is completely disabled.

with DFSO disabled it shouldn't be doing that - looking at your log pics, LAMBSE is still 1.08 so EEC is commanding the right AFR, its beyond me why your pulsewidth is 0ms.

Do you actually see LAMBSE go to 1.5, instead of LAMBDA?

No, i do not. I never see it commanding anything out of the ordinary. As far as I can tell It chases the lean condition when it happens but I cant figure out for the life of me how its dropping below the minimum pulsewidth set in the computer and why I would see 0 pulsewidth. Hoping Decipha has time to look at my tune and logs eventually.

If I have DFSO disabled, how is it DFSO?

its obviously not disabled

I have set dfso time to enable to 15 seconds and dfso minimum ect set to 254 and minimum DFSO speed is 25mph. It happens at any speed only cold below 120ish. I can decel when warm forever and it never shuts off the injectors. So what else would I need to change because I am pretty confident its disabled.
