This new firmware has been tuned to better meet the requirements of today’s race cars, which are achieving lower E.T. and 60 ft times than the original firmware allowed for. The older firmware is proving to be too sensitive early in a run and not sensitive enough down track. This new firmware version 1.6 should correct this situation as well as utilizing a new Self Learning algorithm.
It is recommended that all users upgrade, as the overall sensitivity is different than the previous versions (approx. 3 clicks less sensitive, old Mode 1 is now Mode 4). Having all units in the field operating on the same firmware not only aids when comparing notes with other racers, it also allows for more efficient tech support if needed.Note- To check which version of firmware you currently have, follow these steps.
1. With the power on (from car or USB), Set Mode dial to 1, and Press the test button.
2. After 8 seconds the Green LED will turn off, then begin blinking out the firmware in Red.
(Example– one blink, followed by a pause, then 2 consecutive blinks= 1.2)Updating the firmware is simple, just follow the steps below.
1. Download and Unzip the firmware file for your unit at the end of these instructions.
