CHECKSUM OK ECU file service

01 How it works

1. Upload the original read of your ECU. The system detects the ECU and software (SW) number.
2. Select CHECKSUM OK. The checksum module for your ECU recalculates your file's checksum automatically.
3. Your file is returned with the corrected checksum. If your ECU has no checksum module, the file is left unchanged and the checksum stays with your own tool.
4. Download the finished file. The system works 24/7, also at night and on weekends.

02 Automatic module

Checksum correction is handled by built-in checksum modules for 63 ECU types. The module recalculates the checksum of your own modified file automatically.

03 Written by engineers, tested on a dyno

Every stored CHECKSUM OK solution is written by our engineers with professional tuning tools — WinOLS, StageX, ECM Titanium and our own Tuning Editor — and the file is tested on a dyno before it is added to the system and sent to customers. When your job matches a stored solution, the system applies it automatically, so what you receive is a solution that an engineer has already written and tested. 2 such solutions have been applied 1 times so far.
