hi,
chaneging the value and the data is right.
but is it only an 0,5 data?

Yes... 0.5 lambda! In other words, -7.35 to 7.35 AFR.

Thanks for your answear. I have'nt read the small word Lambda . My mistake. Ok and set it to zero is an 14,7 AFR.
Are my XML correct?

<scaling name="AF3 Lambda" units="Lambda Additive" toexpr="x" frexpr="x" format="%.4f" min="0" max="255" inc="1" storagetype="float" endian="big"/>

<table name="Closed_loop_fueling_target_comp_RearO2" category="Experimental" address="2C91C" type="2D" level="1" scaling="AF3 Lambda">
<table name="X" type="Static X Axis" elements="2">
<data>Low</data>
<data>High</data>
</table>

Yup - that will do it.

THX
Ok I will set it to zero and looks what my car does. Maybe I will remove my rear lambda completly. You have testing it what the ecu does without an rear O2?

Unfortunately not - my motor spun a bearing, currently busy with monster build no. 2.

Oh s***. It was an EJ25 or EJ20 Engine? I'm an mechanik at Subaru I Know the work of an engine rebuild. What are your plan for monster build #2?

EJ257.

EJ257, Darton sleeves, 102mm pistons, 2.7l Stroker kit, cams/springs/valves, hybrid garrett gtx35r with 1.06 housing, twinscroll ceramic coated exhaust housing + manifold + uppipe, FMIC, meth... yeesh, and a whole bunch more (of course, ACL bearings, bolts) oil pump, friggin oil pick and sump (that's what killed my current built block, of all things...), a ton of suspension/bushings/mounting mods to deal with the power, and a whole bunch more which I'm forgetting

I was running a built block with a Dom3XTR and as much TMIC as you can fit in there, meth and a whole bunch more till it blew, it was silly powerful already.

This should be even more fun.

Hi,
I've flasched the new Rom yesterday with set the Rear O2 fueling target limit to 0.0000 at high and low value. On my MTX-L I've seen at WOT before an 10,5-10,6 AFR. Now after reflash it is at 11,5-11,6 at WOT. I have'nt make logs after the reflash. Only by looking to my WBO2. Why is my AFR at WOT 1 AFR leaner? At idle it was before 14,2-14,3 and after reflash it is at 14,3-14,5.

Check your D trims, you might need to tweak your MAF scaling a little.

Hi,

my d trim is 2,4. Yesterday evening if the car was cooled down after an restart I've heard an sound like an broken exhaust gasket. I'll chek this bevore I make an MAF rescale.
One positive think is at idle I rev they are no backfirings. Before reflash the car has enaugh backfiring.

Yeah, check that out before messing with scaling for sure.

Any Chance you could find these in the A2UJ000J rom for an 07STI? ive been trying to limit ANY adjustments on my subaru as the front 02 sensor is already behind the turbo.... Thanks in advance!!!

I'll have a look for you.
