Hey guys, kind of at a standstill here with my tuning, I am trying to data log with my x4 and live wire. Problem is my x4 won't read the AFR at all. Says zero at all times and there's no AFR on live wire. Tuner obviously needs the AFR and SCT is closed on sundays and won't answer any emails I have sent to urgent support. The device is updated and everything. What am I missing here??
