They're renting it. Yep, for ¥294,000 ($3,090) you get ECU and TCM modules for 24 months, but after that time, you'll have to either return the computer units or pay an additional ¥31,500 ($330) per year. It's a standalone package that can be added to any GT-R, including the SpecV (pictured).
But for that price you'll get better low end torque, higher max boost pressure and better low-end boost response, plus quicker downshifts and the speed limiter raised to 199mph (320km/h).
Still, we have to question the choice of the rental model - though there's every possibility it's to get around some bizarre Japanese law - even if it does come at a relatively affordable price, given the GT-R's overall expense.
But, oddities aside, combining this latest electronics upgrade kit with Nismo's previous upgrade offerings or even the standard Nissan upgrades announced earlier today ought to provide enough pep and reinvigoration to make those early-adopter GT-R fans feel almost like they have a new car.
