I have an EcuTec ECM tune that I want to change due to new equipment. The original tuner has gone out of business. I brought the car to another EcuTec tuner and they were not able to flash the ECM saying they did not have the first tuner’s license code, effectively making the tune locked. This doesn’t make sense to me. Does anyone know how to delete the EcuTek tune and overwrite it?
