Hi, was wondering if anyone knows of a good ECU for my BA falcon ute? it's a 6 cyl.

just go out and spend 2500k on one of those top of the line motecs they run in the v8 supercars, would give you awsome wank factor. if however on the other hand you want power, try other mods first.
the factory ecu does a fine job with stock motors funnily enough.
