Chr0m3 I had a proper look this time, you are correct original information I provided is incorrect and is in the IAC area.
I'll go back and put a comment with a correction in the earlier post to avoid future issues.

To get the vehicle to hold first gear in D1 change $01 to $00 at $424F.

I’ll need to double check. It should be for the maximum gear available when D1 is selected. Normally this is set to 2 causing the upshift and changing it to 1 will make it hold first.

EDITED
Original information deleted as incorrect.

Correct change is:

Post up the bin file you’re using and I’ll have a look.

I’ve used mine in a VT with the Moates G6 adapter without a problem and there a 27C010 chip which are 128k bins. I think you can even use a 27C040 chip with the G6 adapter and switch between 4 different bins.
Not sure if there is anything special about the G6 adapter.

May need to change the echo settings in the ADX.

The 5 speed autos were only ever fitted to the SV6, Calais and Adventra, all with the high output V6. The lower models had the low output V6 and 4 speed auto.
All Calais and Adventra 5 speed autos would have had traction as standard .
The SV6 Ute didn’t, not sure if it was an option.

Idle A/F Ratio vs Coolant is commanding around 14 AFR which is what you have in the second image. The first image is only 13 runtime so probably has some of the Initial Run A/F ratio offset vs coolant in it so commanded AFR is 13.6. I agree with Antus that the O2 sensor probably hasn’t warmed up eno...

I would guess it may be stock and require vats off. Can you remove the blue cover and take a photo of the chip?

I would take a guess that the memcal needs the VATS (vehicle anti theft system) disabled. If you can take the cover off the ecu and get a photo of the memcal and see if there are any stickers or writing on it would help to confirm.
