There is other plug-n-play option other than the AEM. There is the Hydra Nemesis 2 for non drive-by-wire with Richard Bulmer being the man to map the car. He is one of the best engine mapping specialist anywhere in the world, Ex Toyota WRC mapper and Ex Motec amongst others.
The AEM system was based on the GEMS EM36 (GEMS designed the AEM ECU originally) so there should really be no problem finding someone capable of mapping it correctly here in the UK.
Haltech also have a new plug-n-play system due out soon based on their Platinum Sport Series, though there is a custom harness already available to allow the use of the Sport 1000/2000 series ecu's.
If you don't mind a little custom wiring then there is also the EFi Technology srl Euro 2 and Euro 4 ecu's. The Euro-4 is around £1600 + an additional £400 for the Can Bus interface, however the new Euro-2 will do everything you need and more and is quite a lot cheaper.
They are genuine oem quality and EFI Technology srl supply their ecu's directly to Honda and Honda Racing (which is run by JAS Motorsport). Mugen also worked directly on the software alongside EFI.
Take a look at the spec's here..

Immobiliser works fine. The central locking and alarm is independent of the ECU so that also works fine. You lose the green key, replaced by the CEL which primes the fuel pump. No CEL when car is operational.

Agree RE Hydra / Bulmer, i'm guessing you are an ex Impreza man like myself? 
AEM is a well priced solution though, and you can often pick them up second hand for 700 ish. Plus there is more mapping support.

Mark, by traction control your talking about the AEM? or after-market bolt-on ecu's?

@ Irvatron
Previous GEMU users, here in Greece, state that the EMU is a bit "slow" compared to other units such as AEM or VAFC2.
Especially at VTEC, they said that the crossover was a bit more harsh dropping first- staying like that for about half a second and the jumping into Vtec.
Is that something that rigns a bell or is yours functioning flawlesly?
Cheers,
Kostas.

Hi Kostas.
IMO that is rubbish, plenty of owner in the US have no such issues like me.
Mines work flawless mate, no such issue at a 4k vtec. Very happy with it.
I think its down to their tune, set the vtec too low or too high without altering timing and NOT getting the optimum point may introduce a stall/bump (when tuning i set it very high then very low and see where the lines intersect for the optimum point). As i said it doesn't only manually switch the vtec on/off via cams like a vafc2 - it takes complete control.
Of course most people dismiss them/don't understand what it will/wont do and how it works.
There are some issues with PnP harnesses but i believe that's been sorted by boomslang etc, oh and the jumpers need to be correct inside.

Very nice.
I really dont understand why more people dont use the Greddy Unit.
From what i know, its cheap, its customisable, it keeps lots of OEM goodies (functionality, cold start, idle etc) and apart from the negative opinions i have heard over here i cant find any good reason why not to go for it.
I always keep second thoughts about what i hear.
Could it be that no tuner here in Greece is able to tune or hasnt spent time with the actual unit?
Could this have caused a domino effect on the GEMU ratings?
Maybe so.
Anyhow, thanks a lot for an explanatory answer.

I'm not sure a mappable ecu is worth the spend for an NA S with bolt ons.
Finding a competent mapper for the EMU is like trying to find gold dust. Gilles tuned EMU's make good power but they cost $1600 and I'm not sure he does them any more.
A second hand, mapped AEM will set you back £1100 or so.
VAFC's are really only good for trimming fuel. Once you go 70mm cat back and decat you start to get very lean - unless you can find a way to add fuel the VAFC is effectively useless. I did get 202whp with i/h/60mm exhaust and 70mm HFC
Unless you plan on going FI mappable ECU's offer a high £/bhp ratio. PNP ecu's are the way to go. Either way gains are only minimal - you'll have more fun with gears.
