Fuel Pump Runs Continuously - how to prevent....?

[LS3_Z4]

Hi,
I am swapping a 2010 Camaro LS3/TR6060 drivetrain into a 2004 BMW Z4. (first that I know of)
It will be California CARB/smog legal......

I have it mechanically in, and reflashed enough to get it running.
Driving around the block is AWESOME - think modern Cobra...........

I am used to vehicles that only enable the fuel pump for about 3 seconds if the engine is not running.
Is that how the LS3 should operate?

My swap has the fuel pump running continuously when the ignition is in "run".

I do not have the Chevy "Fuel System Control Module", so am running the output from the Chevy ECM connector X1-50 (through a signal inversion transistor) to the BMW Fuel Pump Relay control. (BMW needs "low" to enable the relay coil)

I have tried the "F0585" (FSCM Fitted) parameter both left at default "yes", and have reflashed to "no".

any suggestions?

Thanks
