Does anyone know what the "D-Jetro" refers to? I searched and only came up with a couple posts, one of which suggested that D-Jetro is the MAP sensor model... so wouldn't all FD power-FC's be D-Jetro models?

Thanks

fq-400

there L- jetro and D-jetro

L-jetro use stock maf ( low end version )
D-jetro deletes stock maf ( high end version )


but it really up to u which one u want .,there also pro but that not produced any more it more for a drag tuning set up than anything else . i have d-jetro on my evo 8 and i like it no problem what so ever with it. not really sure about it on a FD sorry but i hope i answer half ur question.

The D-Jetro model eliminates the MAF on cars that came with it stock. I don't think they made them for our cars, although they did make the PFC Pro model. The pro model had a two-step and soft rev limiter (ignition based rather than fuel cut).

From the Skyline PFC FAQ:

"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." - 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. Consideration needs to be taken into account when placing the map sensor (or map sensors) for the Djetro system to avoid idle problems on multiple throttle bodied engines.

# Tuning will take considerably longer
It will take considerably longer to tune a Djetro PFC over a normal LJetro PFC. This is because all of the work has to be done from scratch instead of just doing the main bits in the AFM/LJetro version. You should discuss this with your tuner and find out the total cost for a Djetro tune."

What is the "Power FC Pro" and do I need it?

The Power FC Pro Spec.CPU has been designed for drag racing use. These units have two additional functions over the regular units: 1. Ignition cut used for rpm limiter - Regular Power FCs cut fuel feed when the preset revolution limit is reached. At high rpm, there is the possibility of knocking when the fuel is cut in high-powered cars. The Power FC Pro CPUs cut ignition at the rpm limit to prevent the knocking that could potentially destroy the engine. 2. 0km/h rpm limiter setting - Allows for the setting for an initial rpm limiter that is active whilst the car is not in motion. This allows for mainting a rpm level for consistent launches.

PowerFC Pro versions are no longer available brand new. You need to purchase one second hand if you want to buy one."

Thanks guys. I got the part number and the seller was in fact selling a standard Power FC for the FD3S. I think he referred to it as 'D-Jetro' because our cars only use a MAP sensor.

i agree d jetro is for maf based cars converting to map.
if i recall didn't the pro come with fuel and ignition cut. instead of just fuel. hence why it has the soft touch ect ect. and flat foot shift.
