The system's main website is That is where the main userbase is and where the engineers who built/maintain the system are.

034 EFI gets its name from the 034 parts prefix that VWAG put on most of the 5 cylinder Audi engines.

Depends on the version, you need to check. But in general, no it is a pain to use. Couple of things. It only sequential fires four plugs. Depending on version timing adjustment is retard only. Not friendly with USB connections. So old it prefers a serial port PC No self tuning capability. Very sensitive to ground connections. But yes it will work. Used it on a 5 cylinder turbo audi and aside from the timing curve being a total pain it worked pretty well. But you have to check which version, as some are crank fire, some are fuel only, etc.
