All vehicle flashing and datalogging for our N54 DI Delete kit MUST be done with the MHD Tuning F/G Series app. The reason for this is that MHD is working towards consolidating the N54 & F/G Series app into a single app with the older N54 app becoming legacy in the near future.
The initial flash will take 8-13 minutes, we highly recommend having a battery charger on the vehicle while performing the initial flash. Initial engine startup may take substantially longer as air needs to be purged from the fuel lines, fuel rail and injectors.
