ECU Tuner Lock Removal
&
Security Removal Service
Our unlocking service is for all LS1, E38, E40 & E67 Tuner locked ECU’s.
This service is for you to send your ECU to us directly, we can then obtain the code from within the unit itself to unlock the ECU and reset the code back to a factory GM key to enable tuning software (ie. EFI Live and HP Tuners) to be able to read the ECU file allowing custom editing to be done.
(We are able to retain the tune file already in place or if requested we can reset the ECU back to a factory tune file)
