They're bank fire, though they're effectively batch fire depending on rpm/load. (I'm not sure how the stock ECUs handle sync/async fueling... been spending too much time staring at $58)

you can run a '730 ecu with the sy/ty code (ID is $58). a little repinning is involved from the stock harness off of a 3.1 but its do-able.
