What I am experiencing is on decel I am very rich at .73 lambda.
After driving for approximately 10-15 mins it finally shuts off my injectors on decel like DFCO is designed.
My research is revealing a possible catalyst setting or it's a hidden parameter we don't have access to and this is normal.
For whatever reason I have never had this problem in the past.
Only thing I have changed prior to noticing this is dialing in my MAF calibration.
Once it was dialed in, I switched back to closed loop and started noticing this.
I tried changing MAF parameters in the 2400-3000hz which is where I land on decel but did not change my a/f. However it was a small adjustment.
If this is normal, is there a way I can at least get this to command 1.0 lambda instead of just pouring gas into my engine during decel?
Or am I missing something here?
I am attaching logs from the same drive. About 5mins apart. One showing how my injectors stay on during decel and then injectors disabling during decel.
