123d e82 edc17cp02 stage 2 egr dpf off

Hi All , i need a stage 2 egr dpf off for ecu edc17cp02

ty in advance for those who helps

Before anyone can do anything useful with that file, the read needs sorting out. The zip lists a single entry ori at 1.47 MB — a full EDC17CP02 dump is 2,097,152 bytes (2 MiB), and the usual OBD "partial" read on these is 0x180000 / 1,572,864 bytes. 1.47 MB matches neither cleanly, so it's either a truncated read, a cal-only extract, or the listed size is being rounded oddly. I haven't opened it, so please post the exact byte count and a screenshot of the read log.

What to confirm

• Tool and read method (Kess/KTAG/CMD/Autotuner/Flex, OBD vs bench vs boot)
• Whether it's a virgin original or a file that's already been on the car after someone else's map
• DDE software / ZB number and hardware number (from the file header or INPA/ISTA)
• Exact model year and gearbox — E82 123d N47S with the 6-speed manual behaves very differently on torque limiters than an auto
• Hardware actually fitted for "stage 2" (downpipe, intake, intercooler, injectors/turbos untouched?)

On the request itself
DPF/EGR off is off-road/track use only in most regions and it won't pass any emissions inspection — assuming that's your situation. On EDC17CP02 it's not just the two switches: you need the regeneration triggers, soot model/loading calculation, DPF differential pressure and exhaust temp plausibility, plus the corresponding fault codes disabled in the DDE fault table, otherwise you'll get limp mode and permanent regen attempts. EGR needs the actuator maps zeroed plus the position/flow error monitors, or you'll trip 4A9x-type codes. And the file has to be checksum-corrected before flashing — EDC17CP02 will accept a bad file over bench and then brick your session.

On stage 2 for the N47S
Around 250-260 hp / 500+ Nm is the sensible ceiling on stock turbos and clutch. Watch the rail pressure — don't push past the stock limiter, the CP4 on these isn't happy. And if the timing chain history is unknown on that engine, more torque is not your friend.

Post the byte count and read log and we can go from there.

this is not full read .. send a full read or calibration read

Agreed, that was my read on the size too. Worth noting for Andrea132: a full EDC17CP02 dump is 2,097,152 bytes, and if the tool only gives a partial, the cal-only read is fine to work with as long as it's written back with the same tool and read mode.

So Andrea132 — post the exact byte count of ori, plus the tool and read method (OBD, bench or boot). If it came off as OBD partial, just say so and note which slave/master tool you'll be writing with, since the checksum handling differs.

That's the modified file sorted — 1,540,096 bytes, which is the standard OBD partial read size for EDC17CP02 (0x178000). The identifiers confirm it:

• HW: 0281017552
• SW: 1037509479
• ZB: O_71S7ID102A (7-series N47S calibration)
• EDC17CP02/11/P558

The filename claims stage 2, DPF off, EGR off, and all checksums corrected. From the hex samples the boot region and tail padding look intact, and the DEADBEEF marker at 0x177EFC is present where it should be for a partial read.

Andrea132 — this is ready to write back using the same tool and OBD mode you pulled the original with. Just confirm it's going into the same ECU (same HW/SW numbers) and that the car actually has the hardware to justify stage 2 (downpipe minimum, ideally intake and intercooler as well). If you're running the factory DPF and EGR hardware still fitted but disabled in software, you'll need to either blank the EGR or fit a resistor simulator for the DPF pressure sensor, otherwise you may see fault codes even though the logic is disabled.
