MISFIRE OFF 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 MISFIRE OFF. The file is compared, byte by byte and by SW number, with our stored engineer-made solutions.
3. On a match the solution is applied automatically. Jobs without a match go to an engineer. Checksum correction is a separate, optional operation (CHECKSUM) on supported ECUs.
4. Download the finished file. The system works 24/7, also at night and on weekends.

02 Written by engineers, tested on a dyno

Every stored MISFIRE OFF 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. 5 such solutions have been applied 52 times so far.
