Yes, re-programming your ECU will void the nissan warranty. You'd be changing the A/F ratio, throttle plate positioning, timing, just to name a few.
If you had the re-programming done and took your car in for warranty work, depending on what they were repairing, they may not even realize that it was re-programmed. But if they do figure it out you may be out of luck.
