Many other "well known" tuning companies are just simple "IT" companies, they are just providing a flash utility to upload firmware in your car's ecu and that's all. Firmwares for them are re-mapping by other tuning companies on market.
This makes a miss communication between real customers and person who really providing changes in firmware.

FLASHEX combines this two options. FLASHEX is licensed WinOLS user with all necessary plugins to making changes in firmware.

Below you can take a look on few screens of re-mapped firmware in WinOLS: (for engine - N20B20A, ECU - MEVD17.2.P)
