Ok guys! Autowerks Bangkok just confirmed they can do my 116i on Monday!
I will definitely be one of the first in Bangkok, or in Asia for that matter who flash tune the F-series.
The tune is offered by Mcchip-DKR Performance in Germany. Gains are +79PS & +80NM (215HP & 300NM). They offer a 5 year warranty on the tune itself. So if BMW overwrites the software, they will do a re-flash. I can also go back to stock, as they keep a backup.
He also said BMW has no way tracing it at the dealership. They are not equipped to read out that part of the ECU. Just error codes and so forth..
I will report back on Monday :P
