OBDSTAR has expanded its ECU service capabilities by adding support for more BOSCH TC298 and TC299 locked ECU data read/write, making ECU operations more efficient and convenient.
With this new solution, users can perform Bench Mode Read/Write after a one-time Boot Unlock, eliminating the need to repeatedly open the ECU housing for future data operations.
What Is New?
Traditionally, locked TC298 and TC299 ECUs require a boot unlocking procedure before accessing internal data. Reopening the ECU multiple times can increase labor costs and the risk of physical damage.
OBDSTAR now allows users to:
- Perform BOOT Unlockonce
- Switch to BENCH Read/Writemode afterward
- Read and write ECU data without reopening the ECU
- Improve workflow efficiency and reduce service time
This enhancement is especially valuable for workshops that frequently handle ECU cloning, tuning, repairs, and data backup operations.
Supported OBDSTAR Devices
The following OBDSTAR tools currently support this function:
- OBDSTAR X300 Classic G3(Key Master G3)
- OBDSTAR DC706
- ECU MasterFull Version/ A Configuration
These devices enable technicians to unlock supported ECUs and subsequently perform Bench Mode read/write operations.
