What is the “D-Jetro” model and do I need it?
The D-Jetro Power FC units carry the same functions as the regular Power FC units but do not require the use of the factory standard air flow meter and use a mass air pressure sensor. Apart from the unit itself, use of the D-Jetro units requires additional parts that vary depending on the model.” – http://www.greenline.jp The airflow meter (at least in the skyline range) does not pose a big restriction in terms of horsepower and one would doubt the use of the D-Jetro. If you really need massive airflow you can always change to 2 x Q45 Airflow meters and use those with the PowerFC. The skyline series are optimized for closed loop operation with an airflow meter. The Djetro version has a few caveats you should know about before you consider using it # Careful placement of the map sensors in multiple throttle body systems With multiple throttle bodies, such as the Skyline GTR RB26 or the Pulsar’s GTI-R SR20 multiple throttle bodies can have bad side affects when using a map sensor system.
