A Mass air flow delete is normally required on highly tuned vehicles where the sheer volume of air passing through the MAF housing causes the sensor to burn out or hit its maximum operating range. A burnt out MAF will slowly degrade engine performance, where as a MAF which has reached its maximum operating range will normally cause the vehicle to enter limp mode. Increasing the size of the MAF housing and rescaling the MAF ECU data is one option, although this is not always practically possible. By carrying out a MAF delete remap option we can disable the function of the MAF and allow the engine to run in a MAFless condition.
Currently the MAF Delete option is only available for VAG based vehicles running Bosch EDC15 and EDC16 ECU’s.
