CG100 III Prog vs. CG Pro 9S12 vs. CG FC200 :
Many users wonder what the differences are between the three programmers CGDI offers — CG100 III Prog, CG Pro 9S12 and CG FC200. Below is a breakdown of how they compare.
CG100 III Prog
-
Purpose / Positioning: Airbag-reset & mileage-reset tool; also used for reading/writing ECU or chip data.
-
Key Functions: Airbag module resetting, instrument cluster calibration, car-body computer repair, car amplifier computer repair, reading/writing ECU & chip data, mileage correction.
-
Strengths: Supports a wide range of airbag modules and many models for mileage correction. Good for airbag and dashboard-related repairs.
-
Limitations:
-
Cannot read 9S12-series encrypted chip data.
-
Cannot read/write BMW ISN.
-
Cannot modify VIN
-
Cannot renew keys.
-
CG Pro 9S12
-
Purpose / Positioning: EEPROM and key programmer — more advanced and versatile than CG100.
-
Key Functions: Reading IMMO/ECU/MCU data, odometer (mileage) correction, key programming, repair of modules (e.g. BMW FRM, Audi ELV, Benz W221-LU), key refresh and matching, and VIN modification for BMW CAS1-4.
-
Additional Support:
-
Airbag resetting — for some models (Volvo, BMW, Kia, Buick).
-
Mileage correction — on certain BMW, Mercedes, Honda, Volvo, Buick, Chrysler.
-
Key programming — for BMW, Jaguar / Land Rover, Porsche. Renewing keys supported on many brands (Audi, BMW, BYD, Buick, Chevrolet, Chrysler, Jeep, Dodge, Great Wall, Hyundai, Kia, Land Rover, Mazda, Mitsubishi, Nissan, Peugeot, Porsche, Renault, Volvo).
-
-
Limitations:
-
Cannot read/write BMW ISN.
-
Cannot modify VIN (in most cases).
-
Overall, CG Pro 9S12 is positioned as a “do-it-all” programmer for keys, EEPROM, mileage, and some airbag work — especially suited for BMW, Mercedes, etc.
CG FC200
-
Purpose / Positioning: Professional ECU/BCM/TCU programmer — focused on deep module programming and cloning.
-
Key Functions: Read and write about 98% of ECU/BCM/TCU data via OBD, bench, or boot modes. Also supports reading/writing BMW ISN and VIN modification.
-
Strengths: Excellent for ECU/TCU cloning, VIN edits, and ISN read/write — ideal when dealing with full electronic module replacement or cloning.
-
Limitations:
-
Cannot reset airbags.
-
Cannot perform mileage correction.
-
Cannot program or renew keys.
-
Which One to Choose?
-
If your main tasks are airbag resetting, dashboard/cluster calibration, or mileage correction — CG100 III Prog is usually enough.
-
If you need EEPROM data reading/writing, key programming or renewal, odometer correction, or working on cars such as BMW, Mercedes, Land Rover — CG Pro 9S12 is the most versatile.
-
If you are dealing with ECU/BCM/TCU cloning or replacement, need VIN modification, or require deep ECU programming and ISN read/write, then CG FC200 is the tool for the job.
