For those looking for 1.8t Aftermarket EMS
I was reading a Perf. VW article about a Mk1 GTI w/ a 20v 1.8t swap... noticed the mention of use of a "emerald fully mapable EMS, tuned by Dave Walker".
I found this website, looks outdated... granted he is in the UK, but maybe he has something to offer for those needing custom engine management?<ul><li><a href="http://members.aol.com/emeraldm3d/">http://members.aol.com/emeraldm3d/</a</li></ul>

I read somewhere that you can get a hefty increase in bhp with the help of a Motec ECU in line with
the stock one. The Motec is fully customisable and has the great advantage of allowing you to get rid of the MAF sensor. It uses other sensor to provide that info to the stock ECU.
Think it was an S2000 article, but this can be done on the 1.8T as well. the Motec M800 ecu though costs an arm and a leg.

Why would you need an M800, for an S2k or 1.8t?
The M4 controls 4 sequential injectors (like the factory system), and also deals with the turbo stuff. Just ask anybody who is in charge of the powertrain on the FSAE car here. Its a brand new F4i engine with a variable vane turbo, on stock internals, using the M4 (an older one at that).
If you must, then step to the M48. M800, IMO and from what I have read on it, is overkill for a 4cyl.
Also, WHY piggy back the Motecs?? They are completely stand alone!
"The M4 uses 3 dimensional mapping of engine speed against throttle position, manifold pressure or mass air flow for improved accuracy. Ignition control gives you the ability to drive your ignition module and set your spark timing to be at its absolute best at all points. Sequential injection lets you fire the injectors at the optimum time in the engine cycle and to adjust this for different engine RPM's."

I quess you're right. It's just that many Impreza owners go for the M800. The stand-alone Motec
sounds great, but I have no idea how easy it is to set it up from scratch on a car like this, and what implications it would have to the immobiliser and other control modules of the car. I think it all comes down to who installs and programs the thing.
Anyway, thanks for the info! =)

Trust me, the M4 or M48 will be plenty to handle a 4cyl turbo (cheaper than the M800 too). You can even have them output to traction control modules and the dash/data logger, but that gets to be messy when its time to program.
Setting up any Motec is not for the average Joe to do. I certainly wouldn't do it unless I had some really good help, a spare engine or two, and a good engine dyno.

Re: Engine dyno? Thats pretty hardcore
And dropping around $3k for the ECU only isn't? 
Engine dyno just allows for easier changes to be made to sensors, parts, etc. Plus, if you toast an engine during testing, its easier to swap engines on a dyno vs in a car...
