Incorrect data record means wrong power class? Used DME or new?

delete working hours in used DME to under 10hours.

delete working hours in used DME to under 10hours.

can delete working hours with ISTA? or need to use Autohex

Must use Autohex to reset working hours. Many engine computers can support different power levels for different applications. Like the MSD80 could be used on N53, N54, and factory-tuned N54 like the 1M. Power class and Vmax lock after like 10 hours of run-time. Resetting working hours in factory-mode with Autohex allows you to code correct power class.

Friend, if you reset working hours, how do you think the DME will change power class on its own? You must do that. Code it. Esys ok. Check powerclass in cas and code dme to match cas.
