hi guys! I would like to hear some ideas how you guys calibrate on idle and on cruise!!!! stock or aftermarket pipe and sensor. thank you

The process is covered in our Practical Reflash Tuning course. It's a case of logging the error between the commanded AFR and the measured AFR and then using the error to make corrections to the MAF scaling curve.

thanks
