Yup, it should - I'll keep looking. Did it make any difference to AF3 none the less?

I can still see AF3 Correction move around, tempted to zero out all of the 5, -5 locations...

Mine is doing the same thing. AF3 does not stay at 0 with tables 0'ed out. AF3 is zeroed and so are the rear o2 comps.



This is just a segment. It usually is between 0 and -1.5ish.

Careful - some of them relate to AF#1 learning and correction, which you'll land up switching off.

One thing I noticed is, correction limits are displayed as 50, -50 while target limits are .5, -.5. Is that simply because of your ECUFlash def file formatting, or am I actually modifying the wrong data

Did some testing today on A2WC522N. Found that correction and compensation limits on different float ranges.

AF3 Correction Limits: 2DF2C (Hex value: 3F000000BF000000, Dec value: 0.5,-0.5)
AF3 Compensation Limits: 2C91C (Hex value BF0000003F000000, Dec value: -0.5,0.5)

Zeroing out those did the trick, my AF #3 correction was steady at 0. What's weird is, AF #1 correction was staying at 0 for about a mile, then started moving around (edit this is normal after reflash). It's harder to test the target compensation zeroing, thus I'm not 100% certain on those values, but td-d found them in the other thread.

So on the correction locations, were you still seeing the 0.5,-0.5 values? I am seeing this aswell and wondering if mayne I am running into the same problem. It seems like you have zeroed out two correction locations?

On correction yes, it really seems to vary based on ECU though. That's what makes this so hard!

The locations I posted are individual cells that are side by side, You zero out two locations with td-d ecuflash example. I wanted to provide each cell's unique location. When you setup a Table as per td-d's example, you will provide the first location only, then the software makes a table and expands to more cell's as defined.

Very cool. Thanks alot!

Can't seem to disable corrections for A2ZJ512I, I've tried zeroing out all of 3F000000BF000000's and BF0000003F000000's and still see it moving around. Maybe having the rear O2 unplugged is the issue, will try to unplug the rear O2 on the Legacy (A2WC522N) and see if it moves around.

Also got around to highway testing the zeroed out corrections on A2WC522N's, did an 80 mile trip @65*F (might be a little short), but got 31mpg actual (miles driven / gallons filled up) not calculated. The car is pretty much stock, Invidia up pipe & Sidegapped plugs, and maybe an exhaust leak that I caused during up pipe install (hence zeroing out corrections helped improve MPG).

I have another long trip ahead of me ~250miles, will see what I get then.

Edit: Well second trip was less then stellar, back to ~25-27 range it was colder (30*F) thus the first trips increase was from warmer ambient temps.

That looks right. There were other mentions of the hex pattern but they werent correct!

Can I get defs. for

A2WD002T
A2WD010T

Cheers.

Any chance for the above defs?

Can someone please provide defs for above. Please

Rear o2 comps for A2WD002T is at 2972C

Looks like the older STIs (pre 2007) have only the adders to AF3 correction, not the limits.
