What lambda on full throttle?

Could someone that has a SECS unit tell me the lambda readings on full throttle?
I am getting 0.75 on full throttle and around 0.99-1 on cruising, when letting off the throttle it goes to 1.38.
Does this sound normal? The car goes alright I was just wondering as it is the first time I observe it.
Cheers.

Lambda 1 is 14.7:1 air/fuel ratio, so your 0.99 at cruising is ok
If you want to see the actual air/fuel ratio displayed, simply switch from lambda to ratio. The instuction book tells how.
