Leon R on here just bought an AEM FIC for his VX, it's just a universal piggyback ECU so it will work for our engines. The problem is finding a knowledgeable person to tune it correctly to our application especially if you end up boosting you rig.
Hopefully he will post up here, he's been posting on Bradzuzu's turbo build thread on the Planet so that's how I know he purchased one.
Also if someone is seriously considering doing this on their naturally aspirated VX then they should definitely re-do their exhaust and intake prior to get the best results, and so you don't need another tune when you add that stuff.
We're eagerly awaiting the results...from the dyno, that is.
