I might have been unclear about this. Let me try again
It goes like this: Power on - open ts - connect to ms - change injection timing from fixed values to use table in Engine and sequential settings - burn - power cycle as requested. Then when I open timing map (It doesnt matter which of them three) back and fort arrow buttons on the window are greyed out as they should. After changing map values to anything, back arrow shows up normally. After I press back it reverts values back to what they was what is normal. BUT this time back doesn't grey out and if I press it, it do change use table setting back to the fixed values in background. This is not what it supposed to do ?
