A-Tap question I got a question maybe somone can help me with. on my A-tap I think it`s version 1.1 or 1.2 or somthing like that, but the problem i have is with the readings for l-trims, s-trims and o2 mv. instead of having one reading for each this is what it looks like.
LTRIM B1 -4.7 CHANGES
LTRIM B1 -3.1 DON`T CHANGE MUCH STAYS THE SAME AT WOT
LTRIM B2 -3.9 CHANGES
LTRIM B2 -3.0 DON`T CHANGE MUCH STAYS THE SAME AT WOT
STRIM B1 -9.4 CHANGES
STRIM B1 -5.5 DON`T CHANGE MUCH STAYS THE SAME AT WOT
STRIM B2 -9.4 CHANGES
STRIM B2 -5.5 DON`T CHANGE MUCH STAYS THE SAME AT WOT
O2 B1 S1 960MV
O2 B2 S1 910MV
O2 B2 S1 890MV
What I want to know is which one is the right one to look at do i look at the s-trims or l-trims for pt throttle tuning. has any one else had readings like this. sorry if this don`t make sense but i`m trying to get my part throttle tuning dialed in but i can`t do that if I don`t know which ones to go by. thanks.

Re: A-Tap question I think you'll find that the set of trims that are changing are current trims.
The set of trims that "don't change much" are averages.
You should concentrate on the current trims - the ones that change.
You should also log fuel trim cell number - every time the cell changes you should see the long term trims changing because they are indexed by the FTC number.
See this image for an explanation of the fuel trim cell number.
Fuel trim cells
The first 16 cells (4x4 grid) are numbered 0 to 15 from top left, moving horizontally first, down to the bottom right.
I can't spell Auxiliary either
