Deceleration fuel cut problem

Post by NOahhhh »

So to start off I I have my omp deleted with a shon adaptor that isn’t hooked up due to fighting constant leaks so I just premix at the pump. I set my decel fuel cut to 9000 to keep my injectors going so I still get lubrication for my seals but it is not doing that. When I let off the gas it just spikes lean like I didn’t ever change anything. It shows this in my logs and on my afr gage while I am driving. I have tried looking around with no luck any help would be great.

Have you tried one of the pops-and-bangs tunes?

That is basically what those do (plus some timing changes).
Download those and have a look see at the tables, maybe there is something you missed.

You can also ask for help on the discord server
