question about turbo ecu

i did a jdm turbo swap and i read here that the jdm ecu does not like to work correctly with the american wiring.
is this every time or just sometimes?
should i give it a shot or could i ruin my car?

Search "N374". No, it won't ruin your engine. It will just fire an injector improperly and cause it to run like crap or stall.

its probably a fuel cut due to something not being hooked up properly

N374 will usually work w/ S5 Turbo.
N374 won't work w/ S5 N/A harness.

Chipped N374 will sometimes work w/N/A harness

No one seems to know *exactly* why
