Hi!

I`m installing a MAP ECU on my car and it says:

Determine which type of air metering system your car has! There are two main systems:

KVF (Karmen Vortex)
MAF/AFM (Mas Air Flow or Hotwire)

I must know this before I install the Map ecu!

Please answer me!

Sincerely

Fred

My car is ODBII, and I only have luck with KVF for some reason. If I set it to MAF my car will not stay alive.
