chadth Posted December 14, 2013 Report Share Posted December 14, 2013 I have a V88 and a PCS TCM-2000 for transmission control and am attempting to implement some custom torque management. The TCM-2000 is sending a PWM signal to the ECU on all up and down gear shifts. I have configured the duty cycle to be 0% at idle and 100% (12v) during shift and am attempting to get the V88 to detect the signal via a GP Input. I have tried every possible configuration I can think of but cannot get the V88 to detect the "switch". I have verified that the TCM is working properly with a meter during gear shifts. I would expect the following configuration to work: Function: GP Input Switch Type: Toggle Pullup Resistor: OFF On Level: High Active Edge: Rising I have also used DIs that don't support Active Edge with the same results. Is there a bug that I am running up against or are my expectations about how the GP Input works wrong? Thanks, -Chad Quote Link to comment Share on other sites More sharing options...
Simon Posted December 16, 2013 Report Share Posted December 16, 2013 With the input set as you have I would expect it to detect the change. You can test the input by turning the pull up on and then pulling it to ground and see if the input state changes. Quote Link to comment Share on other sites More sharing options...
