2011 TE630 (700km's on the odo):
I started a log of my initial JD settings and then went riding (on my own personal test track
).
Initial settings:

Elevation (according to GPS) is between 50-80 metres ASL, and todays temp is 22 C.
So, what did I find?
The Arrows ECU is waaaaay rich.
Removing the Arrows cans was a bit of a giveaway, they were soooty black like an old diesel exhaust.
The recordings with these settings, all in 5th/6th gear, showed AFR's down in the low to mid 11's.
I ended up with:

More time needs to be spent (low on fuel) as still working out the way the JD tuner transitions from yellow to red, I get a nice low 13 on yellow as it climbs the LED's up to 7 but then as 8 lights up green it drops to mid 12's.
A big thumbs up for the tunability of the JD though, any 1/2 step increments are clearly visible in AFR results.
I wonder if I should pop the stock ECU back in and work out settings for it?
Could be of some help to others in Oz with similar setups, temp/elevation, and fuel.
