Fast rpm drop on long decel
If I leave it in gear and do a longer decel, 10 seconds maybe, I believe it goes into dfso pulling fuel, once I clutch in it’ll go rich and the rpms drop way too fast and overshoot idle and it’ll surge a bit. I can easily avoid doing this but thinking it’s not right and I have adjustments to make. What specifically should I be looking to adjust? Dashpot is dialed nicely this only happens on an extended decel
