Sometimes, a customer who has already made modifications to a vehicle wishes to upgrade it with an additional option or a more advanced stage.
If the vehicle has already been prepared, it is imperative to perform a real reading to preserve or analyze what is already stored in the engine control unit.
Please note that if you perform a virtual reading, you will be reading an original file hosted on a server.
Once this reading is done, you have two options:
1. Send the file by selecting the "Tuning file review" option.
This option is preferable if the vehicle you are working on has already been modified elsewhere than at OLSX.
The person handling your request will analyze the file and provide an opinion on whether the modification aligns with what your customer has stated and if it is possible to retain the modifications. If there are anomalies in the mapping present in the ECU, it may be necessary to start from scratch.
2. If the vehicle is already modified at OLSX, you can simply start from the existing vehicle sheet in your OLSX history and send the file for the stage upgrade.
ATTENTION:
During a stage upgrade request, a Slave user should only pay for the added option.
A Master user, on the other hand, will need to repay the entire request.
