fuel mixture codes

Just installed a jb4 g5 and immediately get codes 29E0 and 2A2B fuel mixture control... I had these codes pop up b4 with the jb+ and my dinan tune but after clearing them and resetting adaptations I never saw them again till now...

Load 17.hex

And do 2-3 WOT runs from 40mph in 3rd gear all the way into 4th. At the top of 3rd is when the tune does most of its adjusting. It should get rid of these fuel mixture codes.
