Correct. - You either need to fool the ECU into thinking it's a standard MAF (with something like an airflow adaptor), or you need to run an ECU that can recognise it (chipped ECUs like Nistune work just as well as stand alone solutions like the PFC).iirc you can not run a Z32 on a std ecu, you will have to run a upgraded ecu like a apexi power FC
