Weird AFR readings

I recently got a tune from Tom and everything has been smooth. There's only one weird thing I noticed with my gauge. If I do WOT on the street going from slower to fast I get good AFR readings between 12.9 and 13.5ish.. But if I'm on the highway already going 60MPH and do WOT, my gauge reads a solid 10 and stays there.. Anybody ever experience this and can shed some light?

My AFR gauge is a AEM wideband.

Thanks,

--Chad

The logs ans a copy of the tune were sent to Matt 3 days ago then he asked for another log and that was sent ,

There is some issues with livelink , I have sent in a few very odd livelink issues weeks ago and still no answer to the issues , can you look into this

If the engineers are not working on this is some one ?, I only posted what I was told

Correct ,The issue is OL wont come on when it should and stay on and at cruise it goes into OL for no reason

At times it goes into OL at WOT and at times it goes into OL then comes back out of OL and closed loop fueling tryes to take over , then when he lets off OL comes on and off or comes on and stays on

On another Focus I am getting 2 totally diff. reading from stft1 is lower case and upper case and others things doing the same , timing is reading 194476287462.82347282 CRAZY READINGS going on and we have gone back to older Versions as requested by SCT

Can you look into this some of this has been some time and no answer to and he is getting kinda upset at me for it

Tom

That would be me.
I'm just upset in general since I'm at a stand still and people keep asking me how much power it puts down and I just shrug. Also I"ve called SCT a few times and nothing gets done and I can't get through to anyone about this and even the stft1 will do tat reading like the timing from time to time and the upper case stft1 doesn't read the same as the lower case.
