# HKS Evo IX

Here are the results for an EVO VIII we had in for mapping today. This car is completely standard apart from an after-market back-box. We mapped it for him on the standard ecu.

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.
Gain: 76.2bhp and 465.9lbft 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%
Gain: 98.1bhp and 114.8lbft at the flywheel

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. This car was running extremely lean throughout the entire rev-range. The car drives a lot smoother through the revs and has more torque and power.

Finally, here is the boost graph. As you can see, the boost hasn’t been raised at all.
