Hello all wondering if anyone can share some knowledge on a lean AFR 16.9 mixture at operating temperature on idle after a Full carbon Karbonius csl box with snorkel install along with Kassel csl firmware, and Kassel map sensor conversion kit. Will be driving to perform a Alpha-N Tune/Dyno. All installed pipes, fittings, clamps are fastened securely, along with the map sensor kit installed diligently. Engine not running perfectly smooth on idle I have a bimmerworld straight pipe and do hear valvetrain noise out of tailpipe.
Also installed the IAT harness connects to old MAF with sensor.
I do not have access to INPA just a obd2 reader that when scanned shows no faults.
*Just a note before installing Kassel map sensor conversion kit it was giving the same issue of a lean mixture I ordered the Map sensor kit thinking it would rectify the issue however it is the same result.
If anyone in the community can help out I would be much obliged.
