seanlivingstone Posted August 10, 2021 Share Posted August 10, 2021 Hi there. We recently fitted a new turbo with an external gate. When we run it up on the dyno, we get to about 4500rpm and we get a massive power cut. Once the car is back at idle, it runs extremely rich for a while and then randomly seems to come good. We have everything in open loop and at the moment we are just relying on spring pressure in the waste gate. We're pretty sure it's something to do with boost control... We've logged all torque sources and can't work out what's causing the issue. We've got several fault codes, and spent a few hours trying to figure it out but we are a bit stuck. Oxygen sensor is also currently unplugged. Thanks in advance to anyone that can help. I've uploaded a datalog, the tune, and also a pic of all the fault codes.
