But… you have to lease it… > **[NISMO renting GT-R engine and transmission computers in Japan](https://www.autoblog.com/2009/05/18/nismo-i-renting-i-gt-r-engine-and-transmission-computers-in-j/)** > > Nissan GT-R SpecV - Click above for a high-res image gallery Beginning June 1, NISMO will begin taking pre-orders on a new ECU and Transmission Control Module (TCM) for the standard GT-R and its SpecV sibling. According to Nissan’s motorsports arm, the ECU increases maximum boost pressure by 0.1 bar (1.5 psi) to crank-up low-end torque and enhance throttle response. The TCM tweaks supposedly deliver quicker downshifts and the speed limiter on the street (i.e. when not running on a GPS-approved race track) has been raised to 320 km/h – or just one tick shy of 200 mph. But as you’d expect, there’s a hitch. Aside from the sizeable buy-in (294,000 yen, or just over $3,000 US), NISMO will only rent the duo of upgraded controllers for a 24-month term. After which, you either return the ECU and TCM units or shell out an additional $329 per year to keep them on board. Both modules are covered by NISMO’s warranty and deliveries begin on June 24 IB zr1 \>GTR fights ---

at least they are warranting it. That’s one hell of a price tag though. too bad there are about a million other things for them to void the warranty on though. aftermarket solutions are probably a better bang for the buck than this. ---

what’s keeping you from just keeping the ecu and not pay for the rent? ---

> [@ubengineering](#): > > 329 a year is cheap, id keep em on word. if u have the cash for a GTR, the time/money to TRACK IT, and buy this shit, then u can surely sped another 300 bucks a year to keep it lol. 3000 is reasonable for the demographic i’d suppose, no poor people buy and track GTRs. standalones are 1-3,000 anyway…then u have to tune…u end up spending nearly the same ---

that is a lot of money for +1.5psi and a improved shift schedule though. ---

the R&D for a rarer, more expensive car isn’t cheap, and neither is hacking the OEM ECU. Its still labor intensive, and needs to be retuned. yeah its expensive…compared to stuff available for Fbods and hondas…but fbods and hondas are a dime a dozen and GTR’s aren’t…plus, its JDM yo
