After beeing at the end of my wits with a 4 year search for an intermittent engine cut and considering selling a car i love to bits. I decided to order can clip and standard rs ecu software. Just wondering if there is a usage guide out there. Mostly interested in: 1. Are there any actuator/sensor tests that need to be performed/canceled on a specic way. 2. Any chance on bricking the ecu with a software update? Found a guide for this on youtube just thought i'd ask 3. If the ecu is locked by tuner is there any way to unlock it? Tuner sold his business and i have no contact info
