Just replaced the engine in my 1998 Escort 1.8 Gti with one out of a 1997 Escort 1.8 Gti, the 97 engine came with the ecu for it and I want to try swapping them over to see which one the car runs best on

Problem is I can't find the damn thing in the car, web searches aren't helping me find it so I'm wondering if anyone on here knows where it will be?

Cheers
