Does any of the following disable evap altogether?

LAMTEMN - minimum of lambda threshold for canister purge control active
CWEVAPDEN

In the country where im in, we run into lots of CEL over damaged charcoal canisters/n80 valves.
If i can find a way to do an 'evap delete', we'll be very happy!

Anybody can teach me how to scale an axis?
Im trying to scale the load axis for hours and im no where, i've googled and searched but still nothing..

i finally figured it out, its as easy as highlighting the value you want to change on the axis and hit the +/- key!
I feel so dumb to had wasted a few hours on this!

I've edited the LAMFA, LDRXN, KFZW, KFMIRL and KFMIOP tables to reflect the load that im going to run on.

Changes done
change LDPBN to 2550 for all
change KFZW to be like jordan
change KFMIOP to max load of 215 at 90% TP
change KFMIRL to max load of 215 at 90% TP
change LDRXN to load of 215 at 6800rpm and estimated the load values from 2250 onwards
change LAMFA to -3% for all

I've followed Jordan's lead on the timing value for a start until i run a log.
Comments pls, does it look safe and decent for me to do a log session?

I notice that in VCDS, the throttle position is always at 99.6% but im still using 90% in the maps, does that mean that when it is at 90% throttle the load will be 215 and by 99.6% throttle, the load will be higher?

Load will not be higher than your 215. Over 90% throttle it just uses the last row values.

Is be careful with the timing. I was pretty aggressive I think. I actually pulled it back some recently.

The lamfa changes aren't going to change anything.  The med9 has a very low bts threshold and from what I can tell is designed to run bts fueling under heavy load (though I could be wrong). I dialed back the kflbts map a bit as it's Realllly rich from the factory.

Oh yes, i do knw tat load will not be over 215 because i want to cap it at 215 for now and see how it looks like.  I do not want to go 230 and worry that something's gonna break.

215 load is definitely achievable rite? What would be a good load if not 215? I've seen people recommending 232 but i do not want to follow blindly.

There's also an 'equation or some sort that will calculate estimated boost when u use a certain load,  how does that work?

I think they say ((load *10)+300)-1000 = boost in mbar approximately

Thanks for e formula jordan.

That doesnt look rite.. If i plug the numbers in, it'll be like 1.1bar and i shd revise load to be higher as i knw tat my k04 mk5 gti used to run 1.6bar of boost..

The above formula is theoritical, just to get  an idea. There is a lot of parameters(corrections or limits) which involved for  the total result.

True! And that formula does not come close to anything that I ever logged on my MED9.1 TFSI. Something around 210 load usually gets me to 2550mbar which is the maximum that can be requested AFAIK.

Ok, sounds like my load is a little high but it should be fine.
I hope that i would nt get torque intervention since the max values are pretty close to each other.

Any other issues with my changes?

Im comparing a defined bin file by automan001 and it looks like the golfR has 3x the map compared to the 8P audi A3.



So,
KFFDLBTS(a) will be used for KFLBTS(1)
KFFDLBTS(b) will be used for KFLBTS(2)
KFFDLBTS(c) will be used for KFLBTS(3)

Did i get the KFLBTS maps right?
Im assuming that the 3 sets of maps corresponds to 3 variants as well?

I've DCC on my DSG golfR, maybe this could be used to sharpen up the throttle response?
Throttle response is done via KFPED

Just to show how rich AFR is.
Picture on top is the golfR and the bottom is A38P i guess.


Does modifying KFLBTS affects AFR directly or do i have to modify another map in conjunction with KFLBTS since KFLBTS is a component protection map??
