Loading tune with bench harness?

Hi guys!

Just built me self a bench harness. One question... Does not a lot of DTCs get active because the engine isn´t hooked up to the ECM? Say I load an ECM and send to a customer. What will happen? Hopefully it resets all DTCs at the end of the re-flash. Can someone confirm that?

Thanks!

By default EFILive resets all DTC codes at the end of the flash. You can change this by changing the options in the Tune Tool.

Ok. Thanks! Will have a look at this when I´m back to work.
