Hey guys I’m new to Hondata, I recently bought a 2014 si and installed a DC short Ram intake and Skunk2 ... exhaust. I ran the base map calibration tune on my car, but after 15 mins driving I got an engine code for “System Running too Lean”. Has anyone else had this issue? I don’t want to mess the car up so I reverted it back to factory until I get more information

I did not datalog it at the time, I will re-install that calibration and datalog it to see what it is. I did notice since installing the factory Calibration base map I randomly will count an engine knock, not even under WOT.. I did datalog 1 knock WOT AND 1 just driving

By base calibration may need some adjustments. If you post a log and the calibration file, I can take a look at it.
