# B-Series tuning examples

Honda Civic (B16) – Rally
Here are the results for a Civic rally car that we had in for mapping. The spec was as follows: Omex ecu, Wossner pistons, TDP built head, TDP throttle bodies and cams.

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%

Here are the before and after mapping results for an EK4 Civic with B18C conversion that was tuned at TDP using an Apexi Power FC.

The car has the following modifications: B18C engine, ecu and loom conversion, cat-back exhaust, an induction kit and a Power FC.

This Image is of the Calculated Flywheel Torque (left side) and Flywheel BHP (right side). These figures are for reference only are are accurate to +/- 5%

This Image is of the Axle Torque (left side) and Axle BHP (right side). These figures are accurate to within +/- 0.1 %
