Dear SparkFun Community, I am integrating the ZED-F9R into a kart for lap timing and positioning. I would like guidance on calibrating the IMU fusion for this environment, where lateral g-forces reach 1.5–3g, engine vibration is significant and as you know the kart does not contain suspension. Specifically: 1. Mounting & orientation: What axis alignment is recommended, and should UBX-CFG-ESFALG be configured manually? 2. Calibration drive: What maneuvers and minimum duration are needed to fully initialize the IMU on a kart? 3. High-g & vibration: Are there settings to tune for high lateral loads and engine vibration on a chassis with no suspension? 4. Model: Should I use automotive dynamic model or another one? Any relevant application notes or example UBX configuration scripts would be greatly appreciated. There is no problem in calibration for a car but for karting it looks complicated. Thank you for your help. ---

Hi @Ketrin , I suggest asking your question on the [u-blox support portal](https://portal.u-blox.com/s/). The users there may have more experience with using the ZED-F9R on a kart. Best wishes, Paul
