Stage evolution explained

Sometimes a customer who has already had a vehicle modified wants to upgrade it with an additional option or a more advanced stage.

If the vehicle has already been tuned, it is imperative to perform a real read to preserve or analyse what is already stored in the engine control unit. Please note that if you perform a virtual read, you will be reading an original file hosted on a server.

Once the read is done, you have two options:

1. Send the file with the "Tuning file review" option selected. This option is preferable if the vehicle you are working on has already been modified somewhere other than BOBPerformance.

   The person handling your request will analyse the file and tell you whether the modification matches what your customer has stated and whether it can be kept. If there are anomalies in the mapping stored in the ECU, it may be necessary to start from scratch.

2. If the vehicle has already been modified with BOBPerformance, you can simply start from the existing vehicle sheet in your BOBPerformance history and send the file for the stage upgrade.

Important: for a stage upgrade request, a slave user only pays for the added option. A master user, on the other hand, has to pay for the entire request again.
