Non recorded Scan Master readings

[dynoman]

Today while out for a drive I went WOT and saw a flash of 800+ o2's & 8* retard but when I hit recall it had nothing there. It does record cause I saw info there before, but every now and then this happens ,any ideas ?? Sam

I think there's a timer. You have to stay in it for something like 2-3 seconds before it will show a recording.

That could explain it because I back off instantly if I see ignition retard.
