hi. so I came across a box of stuff when a customer dropped off their old mustang....it contained a complete 034 EFI control system.a standalone it seems pretty similar to megasquirt,simple,and apparently according to anecdotals it can run an LS with 8 injectors/coils,boost etc etc and let you tweak every aspect of it.im looking to build my 77 MGB in the next year or so,and already have a truck 5.3 LS,and now buddy doesn't even want his EFI kit,sooooo..... anybody used this system?any info on it as to function,problems etc? any info whatsoever would be welcomed

The system's main website is www.motorgeek.com. 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.
