Wah! Nice... Tommy Kaira !
Do you have any pictures?
What else did you install apart from the ECU? From local experience over here in UK, remapping for NA engines offer very little benefit. Remapping for turbocharged engines offers a lot more gains.
From the little reading I've done on VQ35 tuning, apparently changing the cams and more headwork will offer a lot more benefit.
Hehehe, if I go for the 350GT, I'll drive it around first while saving up, then might get a low-compression Cosworth shortblock with twin turbos... YUMMMM
Well, beside the ECU, I only change into HKS spark plug, HKS SLD, and HKS suction kit. Others than this, everything else is stock, but bare in mind that, it already been modified in Japan by Tommy Kaira factory before it been delivered to me. The modification done by them are: Muffler, Manifold, Transmission (gear ratio been changed), brake system, wheels, seats, suspension, power steering pump, and etc...So, the response time I get is much better than standard or Nismo version 350Z.
Here are some picture that I taken while the tuner is remapping and installing the ECU on the 350z and sorry for the quality of the pictures as it was taken by my handphone. More if you would like to see it....cheers and have fun...:wavey:
