maybe 10 hPa diff in lde is nothing to worry about when setting (unsetting really) B_lddy.

I will have to check my xdf/file.

I know that I addressed this.

Can you cross ref with the 5120 file posted by me? I'd like to know if i'm posting known bad images Sad

in BGRLP-BPSPMV there is a division by 2.0. Should this division constant (2.0) be rescaled? This would affect psp_w .


mov     dpsmp_w_word_382038, r5
mov     r7, r5
sub     r7, dpsdvs_w_word_382036
jmpr    cc_NV, loc_86BB58
mov     r7, #8000h
subc    r7, #0

loc_86BB58:                             ; CODE XREF: BGRLP+2DE
ashr    r7, #1     ; division by 2
add     r7, dpsfg_w_word_381E58



I'm not seeing this in 551M... is this for a different ecu?

Yes, that's from the well documented TT file.

What are you doing for the hard coded 10 hPa in LDRPID-MAIN for Hysteresis to set B_lddy ?

It's 8bit and hard coded #1. So, it can't be divided. Does that mean B_lddy is broken now? Or at least now considered 20 hPa (twice the left set value for Hysteresis)?

Not an issue in S4 M box.

B_lddy is set if lde > 0 and less than UMDYLDR, clear otherwise.

I will check it out in the next few weeks.

I ended up including everything, even if not applicable due to CW. For example, I have a TON of BKV stuff in there.

Hmmm. I read the FR as b_lddy is set above UMDYLDR and cleared when lde falls below 10hPa.

10 vs 0 hPa I can see being different without deviating from FR. But B_lddy not being set above UMDYLDR on the M-box greatly differs from my FR understanding.

But I've never looked at the mbox. I'm wondering if changing the 10hPa to 0 would be better than leaving it at the rescaled 20hPa, to be more like the mbox.

The factor is 10, so 1h is 10hpa.

Yes, you are correct. I wrote that too quickly.

B_lddy is clear if lde <= 0 and set if lde > UMDYLDR.

10 or 20 hpa hysteresis wont make a world difference for B_lddy, it is a ver small increase vs. what a sway in boost would make for performance.

I tried to implement this into my S3 AMK/BAM ecu but i endet up with a lumpy and little bit richer idle and rough gear change.

Attached you will find a log

Thanks everybody for the info you shared! Using posts in this thread + FR + IDA + 3 sleepless nignts I've successfully converted my 1.8T 032HN1 box to 5 bar.  First run at idle was impressive, I didn't expect much success from the first run. Night run on full load & full boost was amazing. Everything is under control. I observe no issues after conversion. Pressure sensor readings in logs were initially divided by 2, so I had to multiply by 2 corresponding me7log variables to compensate. From the logs I see that ps_w reading is correct, rl_w is also good and as expected, lamsoni_w shows proper numbers. It's cool to have more than 2.5 bar boost fully controllable. Increased my everyday boost to +1.65 bar & limited torque a little bit on 1-st and 2-nd gears, 3-rd gear now pulls very strong. But now with such pressure and +30C outside, my intake air is slightly hot (50-60C), so I will need to think about bigger intercooler.

Which 3.0 bar sensor part number is best for working with the reference 5120 m-box bin? I only see 4.0 bar part numbers mentioned in this thread.
