RMweb Premium buckleywells Posted March 21, 2023 RMweb Premium Share Posted March 21, 2023 How do you do this? I want to reduce the maximum speed of a Hornby Castle loco fitted with one of these chips. Have read through instructions several times , nearest i can get is something to do with CVs 150 and 151 which I dont understand. I use a Roco z21 control system which can read and program CVs. Any contributions gratefully received! Link to post Share on other sites More sharing options...
RAF96 Posted March 21, 2023 Share Posted March 21, 2023 CV5 is top speed and cannot be adjusted. CV150 is the motor control regime and how it reacts to throttle, nothing to do with speed range. Link to post Share on other sites More sharing options...
