Set the scantool units to metric...

so 14.5 psi would be 100 kPa (much easier)...

Log shows commanded AFR 14.17 in CL which matches B3601 in your tune...

are you seeing AFR 12.1 on your wideband...? I don't see any logged wideband data in your log file.

[danny68ss]

Yes that is what it shows

Since you're running SD (MAF-less), your VE table is not correct

also note that you have LTFT disabled but CL is still enabled... you have to set B4205 to 284F to disable CL

( otherwise it will run CL but without applying LTFT since you have LTFT Correction disable (B3801) ).
