Nissan Skyline R33 GT-R

Here are the results for a Nissan Skyline R34 GT-R that was in for mapping today. This Skyline had breathing mods and an aftermarket fuel pump. It was mapped on an Apexi Power FC. Unfortunately, we couldn’t do a before and after comparison as the car was detonating too much on its previous map.

* Please note, in the below graphs, the red line represents the car’s performance on high boost (approx. 1.1 bar). The blue line represents how the car performed at low boost (approx. 0.89 bar)

The first image shows the torque (lbft) on the left hand side of the page, and power (BHP) on the right hand side of the page, measured at the hubs. The torque figure is the ‘true torque’. It is calculated by: the torque produced at the flywheel multiplied by the gear ratio and the final drive ratio. The power figure is the power produced at the axles.

The second image shows flywheel torque (lbft) on the left hand side of the page and flywheel power (BHP) on the right hand side. As the title suggests, this is the torque and power that is produced at the flywheel. These figures are estimated and are correct to ± 5%

This image shows flywheel torque (lbft) and AFR. The torque produced at the flywheel will be displayed on the left hand side of the page. The right hand side of the page shows the air-fuel ratio.

Finally, here is the boost graph.

Here are the results for a R33 GT-R Skyline that was tuned at TDP using the HKS F-Con V-Pro Gold ecu.

The car has the following modifications: full turbo-back exhaust, air filter, after-market front mount intercooler, Z32 air flow meters, twin TD-06 turbos and a HKS F-Con V-Pro Gold

The car was set-up on the Dynapack for max torque and response rather than high end horse power as the car is road driven.
