Swapping ECU's?

[RacerFreakXXX]

First you need to look at how people are influenced, people don't buy tuner magazines any more. Yes, I know some people still do, but since the economy went down hill magazine subscriptions were the first to go. So people go off of what their friends have and what is known.

Most people look at the yaris and don't see its potential the same way they do at a mini cooper or a miata or a civic. Maybe it's because this is the first real generation of the yaris in America that has caused people to start tuning them. Either way you look at it, the market for yaris performance is not in demand. There is a blitz supercharger, that still needs to be tuned to work properly and a zage turbo kit, that needs a better turbo and oil pan. The zage kit could have easily been copied by greddy or hks or any other tuning company. I don't understand why this is, when companies make stuff for a rolling brick (Scion XB). The yaris is more aerodynamic and a better car on the track. It's all comes down to who the car is marketed to. Maybe it's due to the economy going own hill while the yaris was becoming popular.

Onto my main topic, can you swap an ecu from an XA or XB? Isn't it the same engine and they actually make harnesses and tunes for them?
