most common used ecu for the 3rd gen is a power fc, and yes it can be tuned using a laptop (only recommended if you know what your doing). Its whats used on my car and my local tuners know it very well.

The Apex'i PFC will come new with a base map. Two options....a "Commander" that you can monitor all sensors, Inj. duty-cycle, temps, boost etc. and make some changes. And with the optional "Datalogit", you can make major changes to the maps, but a professional is highly recommended.

The general consensus is stay away from AEM for the FD.
You have a few options depending on your overall goals and level of modifications.
There are some piggyback ECUs that work very well for a given set of mods - Pettit, RX7.com and possibly others from the UK or Australia or Japan that we never got here in the US.
Then there are standalone ECUS such as the Power FC (aka PFC), Haltech etc. All of these can be programed to fit whatever mods you want to add to your car. The benefit of the PFC is that it plugs into the stock engine harness. Some ECUs have base maps that work for a typical setup. The PFC has a base map for a car close to stock mods. All standalone ECUs require the knowledge to tune the timing and fuel for your given setup. If you don't have that knowledge, learning can be time consuming and expensive if you make a mistake. If you are going to have someone else tune the car, then they NEED to have experience with that ECU AND they need to understand how the rotary works so that they don't blow the engine using the same tuning approach applied to piston engines.

hi guys,
thank you all for the help.
the pfc unit seems interesting.
my questions for that unit are:
can this unit drive the omp?
aws?
i heard some problems with the ac.
thanks!

ok guys,
many thanks!!
i will go for a pfc. this time i have another problem :
will the pfc will be ready to work as i receive it?i saw that there is a map already but i assume that this map will be for the stock sequential twin setup. will this work? if its setup is for twin then it will be like the stock ecu.still having trouble?
can i order the pfc with a single turbo mode ?
what can i do?
find a map for pfc? where?
my problem is that at my area there is none to setup the pfc . i must do it myself with your help
is it so dificult?
i have the stock injections and fuel system. is it a problem too?i am not going for 500ps.
i changed the intercooler and now i am fiting an areomotive fuel pressure regulator .
the air pump is removed
egr is removed
double throtle is removed
thats all i have done so far.
thanks again for your suport

What are your mods? The base map is OK for use with sequential twins and some air flow mods.
For single turbo, the tune (timing, fuel etc) needs to match the air flow needs of the motor and turbo and intercooler, exhaust etc. Different turbo setup, different exhaust setups will require different tuning of the fuel and timing to match the air flow. A map from another single turbo might be close. It requires knowledge to safely tune/adjust the ECU to work with the air flow needs of the motor. Some people are capable of learning that on their own. Some are not. Some think they are.
Some people say that a good approach is to use the ECU for which you have a local tuner if you need a programmable ECU to fit the custom needs of your motor.

I think you indicated you still have AWS. Personally I would recommend you delete that as well. There will be no issues with the PFC for deleting any of those.

Jim , thanks
the regulator is a gift for a friend . i have it so i will fit it. also i read ate the aeromotives instructions that the pulsation dumper is no need anymore . do you suggest to remove it or leave it? i heard stories that it broke and the car cought fire.
the injectors will be my next step. for now i am thinking the ecu upgrade .
i want to leave the boost at the factory 10psi max because i do not have any ceramics apex seals.am i right? can i change the injectors and increase the boost without ceramics?
thanks!!!

Its not the ceramic apex seals that limit how much boost is safe to run. It is injector capacity and duty cycle. The stock fuel injectors have enough fuel for somewhere between 12-13 PSI (I forget exactly). You generally want injector duty cycle under about 86%.
Once you have an ECU like the PFC, you can go with larger secondary injectors and change the settings in the PFC to manage the larger injectors. Lots of people get the secondaries bored out to 1200 or 1300cc by RC Engineering.
Many aftermarket FPR incorporate their own dampeners so the stock FPD is rendered unnecessary. The FPD can leak over time (probably due to heat exposure) and can cause fire if not fixed.
