josey Posted June 23, 2020 Report Share Posted June 23, 2020 Hi guys, please if you have any experience with non contact speed senders dont be shy give advice just bought gps speed speed sensor sender (suppose to be 20hz) which it seems its 1hz only. i got speed update every 1 second (check in log) which is way to slow for my needs. 100hz, or even 50hz should be enough, if it is possible to get that response from standing still. I need it for 4wd drag race car, to set up TC and shift light. If you have any other idea including 5th wheel as ground speed sensor, please feel free to give advice. thanks Quote Link to comment Share on other sites More sharing options...
paulr33 Posted July 6, 2020 Report Share Posted July 6, 2020 Can you use an accelerometer instead to detect lateral movement beyond a fixed value when standing still That’s what the Apexi RSM uses , a wired in g-sensor to detect when the car isn’t moving to trigger the “READY” sequence then any lateral movement starts the timer. You could use the same concept using a g-sensor Quote Link to comment Share on other sites More sharing options...
