Not to rehash the KISRM vs 10.13 scaling, but does anyone see #999h or #510Ah as the hard coded 10.13 ? If so, how does that equate to 10.13 with any of the hPa map factors?


Code:
mov     r4, #510Ah
extp    #0E1h, #1 ; 'ß'
movbz   r5, ftsr_byte_384865
shl     r5, #8
mulu    r5, r4
mov     r9, word_FE0E
add     r9, r9
mov     r9, word_FE0C
addc    r9, r9
jmpr    cc_NC, loc_866918

mov     r9, #0FFFFh

loc_866918:
mulu    r9, r7 ;KISRM
mov     r4, word_FE0C
extp    #0E1h, #1 ; 'ß'
mov     fvisrm_w_word_384AA8, r4
mov     r5, #999h
mulu    r4, r5
mov     r5, word_FE0C
mov     r4, word_FE0E
mov     r2, r5
shr     r4, #11
shr     r5, #11
shl     r2, #5
or      r4, r2
mov     fvisrm_w_word_381E66, r4

Seems fvisrm_w is defined once (384AA8) for use in BGRPL and then multiplied by #999h (381E66) for use inside BGSRM. DOC doesn't state this. Or I've incorrectly identified the variables.

Still not having fun.

Here's the 4Z7907551R file with the 5120 hack, It's still set up for the stock 2.5 bar MAP sensor. The xdf is a bit disorganized (I moved a lot of the maps that I was tuning into the top category so I could see them easier) but it will display the correct hpa values in all the maps that were changed.

I can now confirm that correct linearisation for 03k906051 map sensor is like the attached picture .

This is the 4 bar sensor I was talking about, didn't realise.. so looks like it will work then. I'll fit it do the hack and see how it goes..

Seeing if others could lend a hand here, I am looking for KFSDLDSUA in my 018CH file. I am finally going through and finalizing my map pack for my file. It exists in the fully defined TT225 file I have, but I can't find it in my file or the fully defined S4 file I have. Daz has given me some info that it doesn't exist in a 518 file he has, so I am at a loss.

Can anyone confirm if it exists in my 018CH, or if it is not used in my file? TIA

EDIT: file attached

I have to agree with Daz i've had a good look through the 518 and 018CH and there's no sign of it...

Went back and looked at the file some more. It seems SDLDSUA is the 16x1 map that needs division in the 018CH file. Both the axis and table are in hPa.

Although the axis does not reference eprom, it's only 1,2,3... with a conversion factor. I am assuming the axis is boost pressure, so that should already be scaled?

EDIT: source for SDLDSUA axis is plsol

Another EDIT: This is from this very thread :facepalm:
...(SDLDSUA doesn't have axis per se, it is hardcoded so you need to shift cells first into 1/2 pressure slots on the axis  and then lower the cell values themselves  by 1/2)...

Julex, I'm not quite sure what you mean by that. Care to shed some light?

With a little bit of reassurance help from Daz with the 1013 asm division here is the 5120 hack .kp for the TT 225 018cb file.

Untested yet, but will be this week..

Anyone spot any mistakes let me know but a good start

Ok, so here is my 018CH 5120 files. ASM divisions are correct.

It drives fine and boost is controlled the same as my non-5120 file, but the only problem is idle. When I blip the throttle at idle, the engine stumbles because it goes way rich. te_w goes up to like ~6ms. Any ideas what I could investigate?

Maybe I am missing something, but when I compared a few scalars your 5120.bin and Stock.bin values were the same.

Just downloaded and double checked, they are different for me?  Huh

I don't find KFDLULS in my ori file.
Can we use KLDLUL behalf of KFDLULS ?
