I just acquired a Apexi Power FC management system, while doing some research I stumbled on a great page while looking for a English version manual basically it explains the actual differences pros/cons…
So I wanted to hear some opinions on here what do you guys think is better? Why?
As well as share this page very informative page http://paulr33.skylinesaustralia.com/docs/powerfc-faq/powerfc-faq.htm
^^^lol don’t you have an ems
Ljetro
Pro’s
-> Out of the box, works great, plug and play nothing more to add/change
PR: This is suitable for the majority of customers
-> Supports factory airflow meters and larger models
PR: This is suitable for the majority of customers and tuners (less fiddling the better)
Cons’
-> Some tuners/owners believe the airflow meter is a restriction
PR: Turbocharged cars have a restriction after the compressor outlet, not before.
-> Once you max out the airflow meter it can’t show any more useful load to the ECU
PR: Once you max out a given airflow meter, move to a larger unit with higher resolution.
If you stay with an airflow meter maxing out (stockish GTST customers) then you basically have the same
load bearing as Djetro customers. Once you peak or reach max airflow (the most the AFM can show) then Load doesn’t increase anymore.
This is dead obvious for stockish GTST customers who do a map trace.
Djetro
Pro’s
-> No air intake restriction
PR: Turbocharged cars have a restriction after the compressor outlet, not before.
-> No airflow meters in pipework
PR: This can be helpful for large twin applications. It may also help avoid chuffing or compressor shuffling.
With correct pipework and bends you should be able to run twin MAF’s or even a big single MAF relocated in the after FMIC pipework
-> Can’t max out airflow meters
PR: This is a valid Pro. But once you max out any airflow meter simply change to a larger unit or more scalable unit.
Con’s
-> You loose load point resolution once you reach target boost (horizonatal shoot across, as pressure never changes)
PR: This would be my main caveat of moving to map sensor system, the lack of tuning points, as the map isnt a 20x20 useable map anymore.
for lazy ppl
I’ve tuned lots and lots of each system…both get the job done and at the end of the day you (as the driver) won’t know the difference between the two.

stick to the stock ecu
