Installed new engine, and got unsolved problems... Options

[Iceman22]

Hi.
This week the workshop finished swapping engine (3s-ge) from a JDM ST202 into mine AT200 (7A-FE). The whole exhaust incl. the cat was also swapped. The new engine only had 80000 miles before the swap.
Almost everything seems too be fine except this:

1. Rough idling and very poor engine performance (feels like 60hp). Engine gets very warm when driving. Also when the engine is cold and I start it, I have to give some gas in the beginning or it will shut down. The muffler is also making abnormal noise.

2. Fuel gauge is showing lowest position and yellow lamp lighting. Before I delivered the car it was showing half tank.


What can be the cause for these problems and where should I start for solving these problems asap?
The ECU hasn't been swapped yet.

And sorry for my bad english..

Ok guys, it appeared to be 3S-FE (jdm SS-I 140hp) engine instead of GE (SS-II)...(I though that all 2.0 litres in japan where 3s-ge)
So I've got less HP than expected and almost the same torque as GE. Maybe there would be more problems with 3s-ge on 7a-fe ecu...
Anyway, the engine is running very well, got no problems at all, only got 80500 miles on it so it will run many years more I believe
I have noticed that the fuel consumption have raised a little compared to 7a-fe, but that should be normal. And finnaly, the oil consumption is normal, I don't need to refill oil every 2-3 weeks like it was with 7a-fe, that was the biggest reason that I decided to get new engine... 3S engines are the best
The power can't be compared to the GT4 I have with 300hp, but it's definitively feel much faster than 7a-fe

Here are pictures from the ecu if anybody is interested and two pics of the new paint .
also added 7a-fe ecu pinouts pic.
