You might want to ask on dirtyolbc or the liberty rs forums for any specific Q's.
I have ran the z4 ecu on a full ej20g before I got my robtune, ran great with the USDM boost control solenoid and sensors. I was running the td05 & gray 440cc injectors that the ecu is looking for.

Mines an AWIC ej20g so I wasn’t sure if the ecu is okay with that, I’m also running the TD05 but I believe I still have the stock 380cc injectors

The difference is the legacy ej20g ecu controls the speed of the pump. I read on the bbs that without the ecu control, the pump still runs, but at full speed.

Like Mike was saying about the AWIC pump, does the ECU still work with the AWIC? Also I believe my injectors are the 380cc grey tops, but if someone could confirm that for me that’d be nice

They measure all the injectors at a lower PSI over there. So their 380cc graytops come out to 440cc injectors using our testing.
Same thing with the ej20k yellow tops, those measure out to 440cc there, and 480cc here.
