So i bought a SCT X4 wireless Tuner a while back now and i can’t seem to get the tune to upload to the car. I follow all directions but it says it’s trying to connect to the ECU but will fail damn near immediately after me pressing upload. I’ll hear some wiring noise like a fan but once the tune fails the wiring noise stops. Any ideas on what’s stopping it?
