hi guys i hve recently got a dtuk box for my audi a5 1.4tfsi b9. I have failed to log afr any how still trying to find a way how to do it since obdeleven pro i have doesnt have this option i am still wondering why will try using elm. Ok so questions is has anyone logged afr with dtuk tuning boxes how much leaner is it from stock values? I know our engines are meant to run lean but from where i come the highest octane rating we have is 91-92 so i want to know if i am fine with the box or should i worry about messing up the car. I will be keeping the car for atleast 3/4years. People who have logged AFR can they share the value/chart and what did they use to log the AFR
