About this service.

Why Tuners and Module Repair Specialists Choose Core Auto Logic

When the standard OBD or J2534 path will not work - locked module, encrypted boot, recovery from a failed flash - we go chip-level. We read EEPROM, repair flash, transfer keys and dump-modify-write microprocessors directly.

Request a Quote
EEPROM and Flash Reads / Writes
Direct chip-level access to common module families: 25-series flash, 95-series EEPROM, Motorola HC11/HC12, Renesas, ST10. Read, archive, modify and write back with full verification.
CHIP
Recovery From Failed Flash
When OBD programming bricks a module - dropped communication, wrong calibration, security failure - we recover chip-level when the standard path is no longer accessible.
RECOVERY
Pin Code and Key Data Extraction
Pull immobilizer pin codes, key-data dumps and security access codes from supported BCM, IMMO and ECU platforms. Used for AKL flows and donor module preparation.
IMMO
Mail-In Service - Nationwide

Everything covered in this service

Every job is bench-tested, logged and documented. No guesswork, no try-and-see flashes.

EEPROM Read & Write
CHIP
We read and write common automotive EEPROM and Flash ICs directly: 93Cxx, 95xxx, 24Cxx series and NOR / NAND Flash in DIP, SOIC-8, and TSOP packages.
Bin File Analysis & Repair
BIN
We analyze raw binary dumps for checksum errors, corrupted map sectors, and invalid header bytes - then correct and return a verified, ready-to-flash file.
In-Circuit and Desoldered Read
BENCH
Chips are read in-circuit where the board design allows, or carefully desoldered and read on a programmer - then resoldered under magnification. We do not damage working boards to recover data.
IMMO Data Management
IMMO
Transponder data, key counts, seed/key pairs, and IMMO-sector data are extracted, modified, or transferred as needed for key programming support and module re-provisioning.
Mail-In Module or Board Service
MAIL
Ship the module or bare PCB. We perform the chip work, validate the recovered data, and return the module with a full work report including the original and modified binary dumps.
Data Integrity Guarantee
GUARANTEE
We never write to a chip without first preserving a verified backup of the original binary. If something goes wrong during write, we restore from backup at no charge.
TOOL CAPABILITY MATRIX

Capable platforms for this work

Platforms used for EEPROM, MCU, flash, immobilizer data, and board-level module work.

EEPROM and MCU read/write
BENCH PROGRAMMER
Alientech / Autotuner / Orange5 / Scanmatik / Flex / VVDI2 / PCMFlash / CGDI / X-Prog The module or board is handled directly; this is not an OBD-only workflow.
Bench/chip access required Bench/chip-level only
Source basis: Bench programmer source packet for chip, EEPROM, MCU, and ECU read/write documentation.
ECU, TCU, and BCM data cloning
BENCH PROGRAMMER
Alientech / Autotuner / Orange5 / Scanmatik / Flex / VVDI2 / PCMFlash / CGDI / X-Prog Used when donor and original module data must be backed up, compared, and transferred.
Bench access required Bench/chip-level only
Source basis: Bench programmer documentation for ECU, TCU, BCM, EEPROM, and flash data.

When Chip-Level Service Is Required

Situations where standard OBD or J2534 programming will not solve the problem and chip-level access becomes the only path forward.

Bricked After Failed Flash
Module dropped communication mid-flash and now will not respond to OBD. Recovery requires chip-level access to restore the boot sector.
Locked Module / No OBD Access
Anti-tamper protection or factory security access denies the standard programming path. Chip-level read/write bypasses the lock when the customer authorizes it.
Encrypted Boot / Secure Gateway
Modern modules require secure-gateway authentication that not every shop can complete. Chip-level service skips the network entirely.
Donor Module Mismatch
Used module locked to a different VIN or hardware variant. Chip-level write rebuilds the EEPROM to the correct parameters.

Common reasons customers book this service

Tap a card to see what triggers this service and which systems are affected.

A failed OBD programming session, a write error mid-flash, or a module that lost power during programming can leave the chip in an unrecognized state. Bench-level EEPROM read/write recovers these modules without OBD connectivity.
Some modules require the original VIN security seed to accept an OBD flash. If the originating VIN is unknown or the module is second-hand, chip-level EEPROM access bypasses the seed barrier so the module can be read and re-provisioned.
Odometer data lives in EEPROM - sometimes on the instrument cluster, sometimes in the BCM, sometimes in both. If the displayed mileage is wrong due to a module swap or corruption, chip-level correction restores accurate data.
A corrupt tune file, a botched ECU flash, or a bin file that needs correction before programming can be addressed at the chip level without a running vehicle - we read the existing flash, correct the file, and write it back.
Immobilizer data stored in EEPROM - transponder codes, IMMO keys, and security seeds - can be transferred between modules or reset at the chip level for platforms where OBD-level IMMO work is not possible.

From quote to delivery

How we move a job from intake to fully programmed and verified.

  1. Describe the Module and the ProblemTell us the module type, vehicle VIN, and what happened: failed OBD flash, bricked ECU, odometer discrepancy, bin file to repair. We confirm feasibility and quote - chip work is assessed per-module.
    Describe the Module and the Problem - Core Auto Logic chip-data-services step 1
  2. Ship the Module or BoardRemove the module from the vehicle and ship it to us. For ECUs with external connector harnesses, we just need the bare module - not the wiring harness. Anti-static packaging is required.
    Ship the Module or Board - Core Auto Logic chip-data-services step 2
  3. Read, Analyze, and CorrectWe read the EEPROM/Flash content, take a verified backup, perform the required operation (correction, transfer, VIN write, IMMO reset), and validate the output before writing back to the chip.
    Read, Analyze, and Correct - Core Auto Logic chip-data-services step 3
  4. Return with Original and Modified DumpsModule ships back with a work report and - for file-level work - both the original backup dump and the corrected final file so you have a full chain of custody for the data.
    Return with Original and Modified Dumps - Core Auto Logic chip-data-services step 4

Frequently Asked Questions

Usually yes. A bricked ECU from a failed flash typically has a readable chip with salvageable data. We read the existing content, repair or restore the base calibration file, and write it back. Success depends on whether the chip itself was physically damaged during the failed flash.
Sometimes. If the chip itself is intact and only the module's processor or power regulation has failed, we can desolder and read the EEPROM independently. If the storage chip is damaged, data recovery is not possible.
Yes. We can read, backup, and analyze tune files. We can repair corrupt bin files and re-flash a corrected version. We do not write unlicensed tunes - if you provide the corrected calibration file, we handle the flash.
We can read and restore odometer EEPROM data on supported platforms. Note: mileage correction to reflect the vehicle's true mileage after a legitimate module swap is the scope of this work - this is not an odometer rollback service.
Wrap the PCB in anti-static foam or anti-static bag, then in bubble wrap. Do not use plain styrofoam or crinkled paper directly against the board. Place in a rigid box. Include the VIN and a brief description of the work needed on paper inside the box.
