Here are the results for Alan Lenihan’s S13 drift car that was in for mapping today. It was mapped on a Motec M4. We have done a before and after comparison with the previous map from Tuner X. N.b. The thin red line represents Tuner-X’s map and the larger line represents TDP’s map.
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: 57.6bhp and 175.7lbft 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: 64.7bhp and 44.6lbft 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 rich throughout the entire rev-range on Tuner-X’s map. The car drives a lot smoother through the revs, has more torque and power and is far more fuel efficient now that it has a TDP map.
Here are the results for a Larry Love’s S14 drift car that was tuned at TDP using an Apexi Power FC ecu.
The car has the following modifications: a full turbo-back exhaust, an Apexi air filter, a front mount intercooler and an Apexi 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%)
