Getting Started

Things you need

  1. KWP2000+ OBD cable
  2. KWP2000+ flashing software
  3. TunerPro
  4. XDF file for the revision of ECU you are using. If you wish to use a different version software than your car came with, read this carefully.
  5. ECUFix (optional, some kwp flashing software will do checksumming for you)

Fueling

  • KRKTE - primary fueling
  • KVB - fuel consumption (MPG in cluster)
  • MLHFM - compensating for MAF housing diameter
  • KFLDBTS - requested lambda for component protection when calculated EGT is above TABGBTS (may require a lower TABGBTS if your MAF is not 100% compensated for in MLHFM)
  • LAMFA - requested lambda when calculated EGT is below TABGBTS

Boost

  • KFMIRL - specified load
  • FLKDHBN - maximum requested pressure ratio
  • LDRXN - maximum specified load
  • KFTARX - IAT correction for maximum specified load

Timing
