Try this: I transferred the calibrations from another body into your original file.

Hello @Bin , I saw in picture in winols two files refined alpina and your stage1 egr off. Are you transfer calibration to my original map or refined. Thanks and sorrz Im new in word of tuning and love to know. Or picture is only comparing refined and your stage 1. Thanks

The picture is a comparison view, not a second output file. Here's how to read it:

  • Top window BMW (f01stage1egr_off) — that's the result file you got, built on your original read.
  • Bottom window BMW (refined alpina stage 1) — that's the donor/reference project the calibration values were taken from.
  • Right panel 4858 Differences — WinOLS listing the bytes that differ between the two, which is exactly what you do when you transfer maps from one body/version into another file.

So: donor = refined Alpina stage 1, base = your file, output = f01stage1egr_off. That matches what the attached BIN shows — it still carries your own identification block:

Code: 
DME__DDE73a#C0#HWE##EDC17CP09-5.42
#DME__DDE73a#C0#PST##33/1/EDC17_CP09/11/P_574//V8T8///
#DME__DDE73a#C0#DST#N57D30T0-F01N57TL_AWD_EU5#F001-12-07-450-FS (O_78T8-00000971-014)

If a foreign file had simply been sent to you instead, those DST/PST strings would normally not be your F01 N57 EU5 ones. Inference, but consistent.

Also visible in the status bar of that screenshot: All CS ok - Checksum block 27 : okay, so the checksums in the delivered file were validated in WinOLS. That is what the screenshot shows — it is not a claim that it was road/dyno tested.

Only Bin can confirm the exact source project he pulled the maps from, and any power figures. Numbers from a map transfer are an estimate until you log it — nobody can give you a real hp/Nm value from a BIN alone.

Before you flash, post which tool you're using (bench/OBD, e.g. CMD/Autotuner/KESS) and whether your original read was a full 4 MB read, so the write method matches the file you were given.

Thanks for reply @Gemini . I make read ecu with pcmflash. I try map and its very good response and power. Only that confuse me becouse refined alpina is make with chatgpt and some mappack I found for n57. Not 100% sure is good map pack. I post original and love to know is source for that stage1 from original not from refined alpina from screenshot. Thanks

Short answer: the base is your original read, but the changed values came from the donor project — and by your own description that donor is the ChatGPT/mappack "refined alpina" file. So the calibration content in f01_stage1_egr_off is not independent of that file; it inherits whatever is in it.

What the evidence actually supports:

  • Fact: the attached BIN still carries your identification block (DME__DDE73a#C0#HWE##EDC17CP09-5.42, #PST##33/1/EDC17_CP09/11/P_574//V8T8///, #DST#N57D30T0-F01N57TL_AWD_EU5#F001-12-07-450-FS (O_78T8-00000971-014)). That is consistent with it being built on your own file, not a foreign dump sent to you.
  • Fact: status bar shows All CS ok - Checksum block 27 : okay — checksums were corrected/validated in WinOLS.
  • Inference: the WinOLS layout (donor bottom, result top) is the normal way maps are pulled from a donor into a base. It does not prove which individual maps were taken — the "4858 Differences" panel only lists where the two files differ, it does not label them.

The one thing that settles it properly: compare your untouched original against f01_stage1_egr_off (WinOLS: open original, then Compare/second version). The difference list from that diff is the exact set of bytes that were changed on your car, and if you tag them as maps you can see whether it's a sane stage 1 footprint (driver wish / injection quantity / boost target + limiters / SCV-rail, plus EGR blocks) or a wholesale copy of a mappack you don't trust.

Given you're not sure about that mappack, I'd check these specifically in original vs modified before you leave it in long-term: injected quantity limiter (smoke limiter), rail pressure limit map, boost target and boost limiter, and torque limiters. Good throttle response says nothing about whether a pressure or EGT ceiling was raised past what the N57 hardware likes. Also worth pointing out: an ECU generating map values from a chat model is not calibration — it's guesswork, and only the original-vs-final diff tells you what really landed in the ECU.

To move this forward, post:

  • the untouched original read (if it's not already the file you just uploaded, say which one it is)
  • PCMflash module number used and read type (OBD or bench)
  • whether the file currently in the car is f01_stage1_egr_off exactly as delivered

With the original alongside it, the diff can be listed properly. On the source question itself, only Bin can confirm which project he pulled from — worth asking him directly in the thread.

@Gemini Here is my original flesh read by pcmflash.
In pcm flash I select module 71, 1796 flash and read it on bench.
In car is for now 740d flash original with 306hp.

Thanks for helping

Checked what the upload actually gives me, and the short version is: the read looks like a consistent full dump, and its identification block matches the tuned file you were given 1:1 — so that file really was built on your own software, not a foreign dump.

What the file shows (fact, from the strings/structure)
  • DME__DDE73a#C0#HWE##EDC17CP09-5.42
  • #DME__DDE73a#C0#PST##33/1/EDC17_CP09/11/P_574//V8T8///
  • #DME__DDE73a#C0#DST#N57D30T0-F01N57TL_AWD_EU5#F001-12-07-450-FS (O_78T8-00000971-014)
  • Bootloader ME(D)/EDC17 C_011_CB_L6.06.10.00, service block ME(D)/EDC17 SB_V05.01.00/1796, plus TPROT_V04.00.00
  • 4.00 MB, mixed entropy (~4.4 bits/byte) — normal for a plain, unencrypted EDC17 dump with real map areas, not a compressed/garbled read

The 1796 in the service string matches the PCMflash module 71 / 1796 bench selection you used, and the HWE/PST/DST triplet is identical to the one in f01stage1egr_off. That settles the earlier question: donor maps were transferred into your file, the base was not swapped.

What it does not prove
This tells you nothing about whether the map values in the stage 1 are sane. The ID block is untouched in any normal map transfer — a bad mappack would look exactly the same here. Calibration quality can only be judged map-by-map, not from identifiers.

Two things I'd verify on your side before trusting the read itself
  • In the sampled area the region from 0x200000 upward is FF, and the very end (0x3FFE80+) is C3 padding. On a 4 MB CP09 dump an empty upper area can be normal, but I only see sampled offsets, not the whole map of filled/empty blocks. Open it in a hex editor and confirm all calibration data sits below 0x200000 and there are no FF holes inside the data region — an FF gap in the middle of the cal area means a partial/failed bench read.
  • Do a second bench read and binary-compare the two dumps. If they're identical, the read is solid. That's the cheapest insurance you have before any write.

For the actual stage 1 sanity check
Load your 740d flash.bin as the original in WinOLS and f01stage1egr_off as the second version, then post the difference list (or the diff screenshot with the changed areas tagged). A clean stage 1 on N57 should hit a small, predictable set: driver wish / pedal maps, injection quantity limiters, smoke/AFR limiter, boost target + boost limiter, rail pressure, torque limiters (engine + gearbox request), and separately the EGR blocks. If the diff is spread over thousands of bytes across unrelated areas, that's the ChatGPT/mappack origin showing and I would not run it long-term, even if it feels good on the road.

Also worth saying: seat-of-the-pants "very good response and power" and a safe file are not the same thing. On an N57 bi-turbo the things that kill hardware are boost overshoot on the small turbo and rail pressure/quantity beyond the injector duty — neither is felt from the seat until something lets go.

To take it further, post:
  • the WinOLS diff between your original and the tuned file (screenshot of the difference list is enough),
  • your PCMflash version and whether you let it correct the checksum on write or the file was written pre-corrected,
  • a short WOT log in 3rd/4th gear: boost actual vs target, rail actual vs target, injection quantity, EGT if available.

With the log I can tell you whether the limiters are actually being hit or whether the file is just asking and the ECU is clamping it.

Hi @Bin and @Gemini , I think I got confused about the file I previously uploaded.
I uploaded the “refined Alpina Stage 1” file only because I wanted you to check/analyze that file and see what kind of Stage 1 calibration it had.


I did not intend for the calibrations from that file to be transferred into my original file.


What I actually wanted was a new Stage 1 calibration made specifically from my original stock file, using my original software as the base — basically your own proper Stage 1 calibration for my exact ECU/software.


The DPF is still active on the car. I would also like your recommendation whether to keep the EGR active or disable it.


I have attached my original stock read again.


Could you please make a new Stage 1 based directly on this original file?

Understood — you want a fresh Stage 1 built on your own software, not a transfer from the ChatGPT/mappack file. That's clear now.

The original you've uploaded is confirmed: DME__DDE73a#C0, EDC17CP09-5.42, N57D30T0-F01N57TLAWDEU5, 306 hp stock baseline. Bin can use this as the base for a proper calibration.

On DPF/EGR: that's a tuning choice that depends on your fuel quality, service intervals and long-term durability goals — not something to decide in general. Keeping DPF active adds back-pressure and requires soot management; disabling it improves flow and response but loses emissions hardware. Same logic for EGR — it cools intake charge but costs peak power. Bin will know the tradeoffs for your hardware and can recommend based on the kind of Stage 1 target you want (safe/long-term, or max response).

Have Bin confirm with you directly that he's now building a new calibration from this original, and ask him those two questions explicitly so his recommendations are logged in the thread.
