Question though, according to CLRKA and CLRHK, rear lamda control is disabled?
So does this mean that they don't do rear lamda control on these engines, and only use it for cat efficiency check?
They're set the same way on the RS6 ROM that I have too...

A few more:
FTSDRLW
FMSTMOT
FSWTM
FSZTM
KFSZDUB
KFSZT
KFTSRL

I think I have a few more items sitting in WinOLS that I haven't moved to the XDF yet as well, I need to go back over it all and check...

There's also 8 mystery maps (10x10, 16bit) starting @ 0x1C0EA, I suspect that they are cylinder filling characteristics, but the values are way different than my reference (which is a flat map), though they seem to match other NA V8 mappings (turbo engines don't use them maybe?)

1C0EA is KFPRGE. I found this explanation: Internal exhaust gas partial pressure of N-dependent adjustment (basic KF) at inlet NWS

How sure are you on that?
I only have one reference with KFPRGE defined and it's a 2x24 map, also the thread on this forum that references it says it's boost load related...

I was pretty sure... Not anymore, I found it in the same place on a RS6 binary.

Yeah, I've noticed a lot of inconsistency in some of the RS6 defs, at least with WinOLS defs anyway.
So far the XDF's haven't been too bad.

Anyone know how cam changeover handled on these engines?
I know it's only used for internal EGR and cat warmup, but how is it done?

I'm pretty confident that there aren't any NW maps, the closest is KFSU (same size as 551M KFNW), but those are intake flap staging.

So, is that code actually stripped out (or repurposed for intake flaps?), or is there any way to enable it and make it useful, maybe tweak changeover switch point somewhere (simple on/off???)

RS6 ROMs seem to be a special case, NWS maps are in the 0x2AXXX range... If I had to guess, I would say code was added on? (that region on my ROM is all 0xFF)

I really wish there was an FR available for this thing. lol

You would be wrong. At the risk of spoiling you:

KFNWSE, NWKHE, NWWLE, NWKHLLE, NWLLE, NWWLLE all exist in these binaries, and vvt is very much used on WOT pulls.

KFNWSE: 19F4E, 8x12, 8 bit (factor .5*x) axis are 1A02E upm (40*x) and 1A041 % (.75*x).

Hmm, interesting... Values in those maps are NOT what I would have expected, nothing like any of the other examples I have (the areas are shaded differently, as if WinOLS thinks no checksum in that area?)

Thanks for the info, I'm no expert on these things obviously, so it's ok if I'm wrong. Wink
Just seems odd that every example I have is a little bit different.

0=at rest
11=transitional
22=advanced/vvt active

Sorta like KFSU and the 0, 1, 2 values....

8D0907551M, it's 8bit and 0x00 or 0x80...
4D1907558, it's 16bit and 0x0A00 or 0xFF00...
8N0906018CB, it's 16bit and 0x0900 or 0xFE00...

Nothing good for me to reference! lol

Edit:
Though I do have another question...
If NWS is indeed used on this engine, why does CDNWS = 0?

Update:
FNSA_0_A
FNSA_1_A
FKKVS_0_A
FKKVS_1_A

I think I have the correct temperature axis for FNSA, though there is another possibility at 0x1830D... So not 100% there.

Need help with KFLF though, I've scoured the ROM looking for it, but closest I can find is 0x188B8, but where are the axis?
Should KFLF be flat, or should it be populated? I've seen both on turbo engines so far, but that's all I have for examples.

i believe KFLF on that should be all 1.001?

Thats how it is in the ones i played with.
