13B2NV

i know the short answer is no but this is what im wanting to do.

i have just mounted a full cut bridge port N/A 13b-re in to my s4 which was a 13bt.

i just was wondering if any one can tell me if it will be possible or what problems i will come up against trying to use the factory s4 13bt ecu to run the injectors on the jc cosmo (13b-re) intake?
iv been told the primaries on both engines are 550cc but the secondarys are 880cc instead of the s4 550cc.
im pretty sure thats a no but im hoping i can at least start it up and get it to idle.
any feedback i can get would be a big help and any low budget way to be able to take it for a drive around the block
cheers
