ECU Flash Tool
UpRev Osiris is the tuning platform for modern Nissan and Infiniti vehicles, combining an OBD-II flashing interface with software that reads and reprograms the factory ECU. It targets platforms such as the 350Z/370Z, G35/G37, GT-R and Titan, giving tuners access to fuel, timing, cam (VTC/VVEL), throttle, boost (on forced-induction), rev limits and MAF/injector scaling in the OEM calibration. Osiris includes datalogging and, through UpRev's tuner-licensing (Cypher) model, lets professional tuners create and load custom ROMs. It keeps the factory ECU and OBD functionality intact. UpRev is a mainstay of the Nissan performance scene. It's conceptually similar to OEM reflashing but dedicated to Nissan/Infiniti petrol ECUs.
Like Softechpro, UpRev reflashes and edits factory ECU firmware — but UpRev is Nissan/Infiniti petrol-specific, whereas Softechpro focuses on European diesel/petrol platforms with automated DPF/EGR/AdBlue/DTC-off modules and checksum correction. Different vehicle families, so the two complement rather than duplicate each other.
