Is there any way to control VVT Switch On/OFF by a 2D map ? Right now it’s off : ![image](https://europe1.discourse-cdn.com/flex013/uploads/ecumaster/original/2X/3/3d9bb341983d4dce55397d0814b99627b07102dd.png) And here we have it on ![image](https://europe1.discourse-cdn.com/flex013/uploads/ecumaster/original/2X/1/19731cff48ba09e2aa7ca58911ab7926db53dd00.png) It’s there a way to switch the state from ON to OFF when it pass over certain RPM ? Right now we have only ON all the way or OFF all the way. Thank you in advance ---

You mean this ? but its a target you need also a good cam position signal ![vvti.](https://europe1.discourse-cdn.com/flex013/uploads/ecumaster/original/2X/9/953a3b26102bfb5ebe0a1bc6596c68d75c200efd.jpeg) ---

Thank you @ngt after I looked at your comment i realized that my cam position signal it’s off now works fine(almost), I need to play with PID in order to make it advance/retard as close as possible to target ![image](https://europe1.discourse-cdn.com/flex013/uploads/ecumaster/original/2X/c/c9027dca0c33727470cd6512be76f098c89fe455.png) ---

Also you will notice your max real cam angle (green line ) drifts in a linear fashion ? usually thats your VR latency crank sensor effect thats been around since the dawn of ECU’s. Try to remedy that by adding input delay on your crank trigger settings. VR sensors have delay, HALL do not (thats what they say xD) ---

By that you mean to add delay on Primary trigger right ? Should i use increments of 10us to see the behaviour? Or there it s a magic number ?
