To start off I did my swap about a year ago now. It was out of a 95 legacy so it has dual port heads. My car is an AT with 4.44 gears and I still have the original 2.5L ECM.
A few things I've noticed and wonder about or am maybe concerned with.
1. I noticed zero fuel economy difference from before and after. I was slightly hoping for at least 1mpg improvement as I read most people have economy gains from this swap which makes sense seeing as its smaller. Anyone who has done this swap have the same results or better?
2. I recently drove a 95 legacy with a 2.2 and noticed the tach shows redline at 5500 where as mine shows redline at 6300 or so. And if I go wide open it takes it at least to 6k before shifting. Am I over revving this 2.2?
I have ZERO issues with this engine and haven't regretted the swap for one second. My concern is if my current ECM allows for it to rev higher than it was engineered for? Or if I got an ECM from a 2.2 car if I would notice a slight economy gain but maybe with a slight power loss?
My local picknpull has these cars constantly so getting a new ECM will be a piece of cake. Curious if anyone has tried this and if its worth it or has zero effect.
