Osiris Tuner from UpRev brings advanced tuning capabilities for Nissan & Ininiti factory engine control units (ECU) to the DIY tuner. With support for most late model Nissan vehicles (2003 and later), UpRev's tuning products are used by professional tuning shops all around the world. Osiris Tuner is intended for DIY enthusiasts who are comfortable tuning their own ECU. This package includes the factory stock tune as a starting point. If desired, a tuned ROM optimized for your vehicle may be purchased from UpRev directly, or from any of more than 100 UpRev pro tuners worldwide. All UpRev ROM files are modified for map switching and real time tuning. Map switching stores up to 5 alternate maps in the ECU which the user can switch to using the cruse control buttons giving the user the ability to change between high octane, low octane, nitrous oxide, valet mode, anti-theft, or whatever the tuner can come up with, all on the fly from the cruse buttons. Real time tuning gives the tuner the ability to adjust fueling, ignition, and other parameters while the vehicle is running and even under load. Real time tuning drastically reduces tuning time and dyno costs.
