Read by protocol will be blocked.

Do you have any tools that will read in boot mode?

I know we can find the problem if you can get the actual file.

Just get a spare ecu

Forget about reading the M7 file, it isn't worth your time.

I am 100% confident in your abilities.

If your KFKHFM is all 1s, but fkhfm is not 1, i'd say either

1) something wrong with the file (i.e. doesn't match FR)
2) KFKHFM isn't where you think it is
3) fkhfm isn't where you think it is

1 That is something I cant verify atm
2 I have adjusted KFKHFM in this file earlier with success
3 The mshfm_w and rl_w is following the fkhfm correction very accurately in my logs

4 The FR diagram does not apply to this file, I found two different diagrams of the GGHFM module, there could be a third. The FR copies I have was written in 2000 and 2001, my ECU is 2002.

Something I have noticed is that my load is higher than requested when this happens, about 20% higher than rlmax_w when fkhfm starts to correct.

Holy f

I just noticed the software number from my M7 file != my stock binary I sent Tapp....

I believe I have a copy of your ori software on my home pc. If you would like I can dig it up and post here when I get back. Pretty interesting thread...

Oh, gotcha. Yeah, I have no experience with M7, but from everything I've seen/read, I think it's high time you joined the dark side....

No it wont.

In the FR and in code the initialisation value is locked to 1.00.

SY_TURBO has no control over fkhfm in ANY condition. It simply changes what fkhfm is multiplied by.

If SY_TURBO is true  then mshfm_w = (fkhfm * 1) * (mlhfmm_w - MLOFS)
If SY_TURBO is false then mshfm_w = (fkhfm * Fkup) * (mlhfmm_w - MLOFS)

In this case SY_TURBO is true, so in short and in code we have:
mshfm_w = fkhfm  * (mlhfmm_w - MLOFS)

SY_TURBO changes how fkhfm is used, but NOT its contents.

SY_TURBO is a compile time option, and as it is set in the file in question, any code to do with fpuk is simply not there.

Here is the initialisation of fkhfm(byte_8A0C) being set to 1.00 (0x80)
sub_6846C:
6846C                 movb    rl4, #80h
68470                 movb    byte_8A0C, rl4
68474                 rets

Here is fkhfm(byte_8A0C) being filled with the contents of KFKHFM (0x10DA0), yo can also see a 16 bit equivalent(word_9F72) value is also created.

sub_68476:
68476                 mov     r12, #0DA0h
6847A                 movbz   r13, byte_F89C
6847E                 movbz   r14, byte_F9B5
68482                 calls   0, sub_7312
68486                 movb    byte_8A0C, rl4
6848A                 movbz   r4, rl4
6848C                 shl     r4, #7
6848E                 mov     word_9F72, r4
68492                 rets

This is the ONLY 2 places in code(original file) that byte_8A0C is written to.
