How can i use Torque (smartphone app) to see if i have an issue with the HighPressureFuelPump and also see the errors that come up for my mini?
You can monitor fuel rail pressure with Torque, if i remember correctly mine peaks around 1800-1900 psi under full throttle
Also... to monitor a faulty HPFP can Torque monitor it when there are no HPFP symptoms? In my case the symptoms (engine shuttering at start up) come and go, when the engine runs ok ad i montor it with Torque will the problem be seen then?
