Tips for Best Timeslip Results

• ProScan continuously polls your vehicle's speed sensor in order to determine acceleration and distance traveled. Therefore, your speedometer should be properly calibrated and wheel-spin should be avoided in order to provide accurate results.
• You should perform your performance runs on a straight road that is as level as possible.
• You can attempt to improve the refresh rate by specifying a shorter timeout value for the ELM microcontroller under ProScan Preferences. A faster refresh rate will allow ProScan to collect more data points, thus generating more accurate results.
• You should perform multiple performance runs on the same day, on the same stretch of road, and in the same direction. Discard the timeslips in which you experienced excessive wheel-spin, and then average the best runs. After changes to your vehicle have been made, go back to the same stretch of road and repeat the process. Compare the before and after results to determine how the changes have impacted your vehicle's performance.
