Ok it's been a while since I posted anything on gt planet. I was sick with mono. But i'm back and starting off by giving you a guide to tuning your Nissan GTR Black Edition. Make sure that you buy all upgrades and change oil, to get 1,121hp Suspension: When you are tuning your suspension, you need to remember that most changes to it will affect various factors such as traction, aerodynamics, etc. A good start is to put your ride height lowest to the front and highest to the rear, but toy around with the hight as there might be a better aerodynamic combination. Spring rate should be close to max for both front and rear, but max spring rate works fine too. I have found that toying around with the spring rate has squeezed out a slightly better launch than a max spring rate. Dampers play a big role, so my recommendation is 1 in the front for both extension and compression, and 10 in the rear for both extension and compression. It is wise to toy around with these, as dampers have a great effect on your car's performance. Antiroll bars are not a big factor(I just left mine alone) but you can toy around with them nevertheless. Toe and Camber should always be 0 as the car is AWD and you want the most traction possible. Transmission: Your GTR's transmission is by far the biggest factor in a good tune(same goes for any car) and it is very important that you find a transmission tune that gives you good launch and good pull. In my experience, I have found that the Black Edition's transmission tuning can be a real pain, as getting the pull you want requires you to give up the launch you are looking for(i'll explain why shortly). Your best starting final gear is between 3.500 and 3.600, as this range gives you great pull in your run. Remember to put your speed all the way down. Some good initial gears are 3.537, 3.568, 3.584, etc. But here is the reason why the transmission tuning is a pain: Your 1st gear. Yep. The first gear has given me so much trouble as it has given others. The problem with having this final gear range is that with first gear being all the way to the left, you get a slight turbo lag which can five the illusion that you have traction control enabled(most evident in higher initial final gears). To get a better launch, move your 1st gear left but not all the way. The more the 1st gear is away from all the way left, the better the launch will be. But this creates another issue. There will be a harder, more sloppy shift into 2nd gear which can slow you down as well. If you plan to continue to leave 2nd gear alone, find a first gear that has a better launch with minimal impact on shifting into 2nd gear. For example, try these ranges(in clicks) as you move your first gear off of all the way to the left: 5, 10, 15, 20, 25, 30 clicks and so on. Remember this rule: Further the 1st gear is to the right, the better the launch but more interference on shifting into second gear. Below are some questions you should ask yourself: 1st gear: How much away from all the way to the left should it be? 2nd gear: Should it be moved evenly with first gear or do you leave it alone? 3rd gear: Should it be moved to it's normal position or further right with 1st and 2nd gear? 4th gear: Should it be a few clicks off the right side or furthest right? 5th gear: Normal* 6th gear: Normal* *Normal means put it to where it would normally go. Once you have your ratios, set your final gear all the way to 2.500. Drivetrain: For maximum traction, set your LSD to 60, 60, 5 for both front and back. Your differential in torque should be 45, 55(can toy around with it a bit). Body: It is best if you remove your rear wing to get the least amount of downforce as possible. Hope this helps!
