Mostly tuners do Trionic 5 (T5) conversions. The performance folks ought to know more. The tuning folks at ecuproject forums have hacked into the 9000 engine management ECUs and made them tunable using software you can run on your laptop. It's surprisingly easy now that they have paved the way. The T5 ECU takes care of boost, fuel, and spark, so it can run your engine closer to the brink of knock, without going into detonation, which translates into more efficiency and more power off whatever gas you put in. It is much more refined than our 900s' systems, which involve stand-alone control for fuel, boost, and spark. Trionic can even detect knock before it starts, by sensing ionization in the combustion chamber via the capacitance across the spark plug gaps. Then it dials back timing on individual cylinders, if it detects a pre-knock state. It's very sophisticated, and you can have it as cheaply as buying a few junkyard parts from a donor car.
It can be as DIY or as "buy it and bolt on" as you want it to be. Obviously if you DIY you pay less and have more control. I think you'd be giving Eeuro about $2500 if you bought all their bolt-ons, but really all you need is a good donor car (any car with T5 - I went to a junkyard). And that's what the T5 conversion is all about: power to the people. You can have an engine management system about as sophisticated as current cars from the major manufacturers on your 900, fully tunable, for a few hundred bucks and a lot of hours of your time. So the old adage about paying for speed is no longer true.
Earth-shattering, no?
The biggest problem is getting a crank position sensor that will work. You can buy that crank trigger flywheel from Eeuro, but who can afford $400 for a flywheel? You can use a stock crank position sensor trigger wheel from a 9000 in place of your air conditioning pulley, but who wants to fry in the summer? You're left with one option, and that is to DIY. You can drill holes in the back of the flywheel with drill press and protractor to mimic the T5 crank trigger pattern - just make sure you balance it afterwards!
