This is half right. Refer to my post below that i had posted a while ago explaining how to do a system in the FR-S/BRZ to get a better understanding.

So the immobilizer in most newer Subaru vehicles requires you to either Option A) Give up a key and use what is known as a 556uw in the industry. This module takes a key hides it inside and reads the chip from the key while the car is trying to start. The chip has lets say a "password" for the car to start. If the password isn't there you guessed it no remote start or regular start. It was very common to see people go and get keys cut from the Home Depot or Lowes after finding out how much a key from the dealership costs. So while the key fits in the door lock cylinder and can lock and unlock the car when put in the ignition cylinder it will turn and do nothing. Option B is the use of a newer bypass module which "learns" the code from the key and allows it to start. So after going through a programming procedure with one of the keys the module learns the code and then supplies the vehicle with the code when trying to remote start. Don't have to give up a expensive key but needless to say the module isn't cheap either.
Now regarding Option B the module I speak of has some tricks up its sleeve. Essentially in certain cars it can learn and replicate through data a lot of the features of the car examples are Unlock, Lock, Alarm Arm, Alarm Disarm, Fuel Door, Trunk Open etc etc etc. If it is a function that is done electronically there is a good chance the module can duplicate it through data. So the thing that sucks about the FR-S/BRZ is the module can only do one or the other so it can either be a bypass for the key or it can learn all the functions of the car and replicate them for you through data. so you may now be asking "Whats the benefit of the module replicating how to unlock my car or open the fuel door?" WELL instead of having to run a wire to that trigger its being done through data! 10x easier and a lot quicker. So essentially for remote start purposes you need two of the data based modules to make things easy at least.

So if u are thinking about the 5704 you have to do either option A or B there is NO, I repeat NO way around it. If you do a Compustar Remote Starter you have a couple options. You have options A and B and then a modified B. So the cool thing about Compustars is that they have a proprietary bypass that plugs into them called BLADE. It literally a card that slides into the brain and does the same as the AL-CA or FLCAN. So you can essentially have the BLADE and a separate AL-CA (don't quote me on this but i don't believe that FLCAN works with Compustar brains for one reason or another not 100% on this and may be getting it confused with something else but your better off with the AL-CA anyways and they both cost the same).
From a install standpoint it is a lot more convenient since you don't have two bypasses dangling somewhere but the the caveat to this and this is strickly from a installation standpoint in that unlike DEI based products(The Viper 5704 you refer to or any Viper,Python or Clifford product) the Compustar doesn't have some internal relays so you may have to add those on which become chunky at times. The relays are important depending upon what you are doing and if your car is a manual I would suggest ignition kill be wired vs starter. So just my .02 cents. I think after reading the thread and what 086A had to do to get the features to work in the manner he wanted I think i am still forced to buy a BRZ even though dislike that front end. Now if i can get it for a good price no big deal.
