Electrical problems in swapped 5AFE Engine

[shanii89]

Aoa. Guys
I recently got my corolla 99 ‘s engine (12 valve) swapped with a japanese 5AFE MT (1600cc) engine.
Now its in running condition from 5 days but there are few problems that i noted
1) Main issue that i noted is that electrician have used 7AFE ecu with my 5AFE engine , he also replaced the original 1 wire oxygen sensor with four wire sensor that comes with 7AFE. According to my electrician 5A ecu are not short in market so we used 7A and it will working fine and also will not disturb the milleage or anything
But i am confused about it

2) Engine is running fine with good acceleration and also engine check light is working But noticed That at idle RPM are high like above 1000 to 1300

3) AC cooling is not good (i am comparing it with swift 2011) and ac guy says that 5A compressors will do the cooling just average. So what do u say guys is it true ?

Kindly Guide me what to do
Thanks

No 5afe ecu is not short. He just didn't have it.
5afe is 1.5. Swap the ecu with original.
AC of 5afe works fine not average.

Ur electrician has messed up 1.8cc engine ecu in 1.5cc won't work properly.

So can you suggest a good electrician In rawalpindi who can replace the ecu and check the wiring if its proper or not
Also who can check AC
May be its wiring is also not good thats why its not working properly

goto @rajaatta in RWP or @dani_kk in islamabad

Aoa. Brothers
I have another confusion
I went to the guy from whom i bought the engine to get a 5AFE ecu but he was again saying but 7AFE ecu works fine with 1.6cc engine.
But now i am thinking that as far as i know 5A is 1.5cc and 4A is 1.6cc.
So now the question is i kept saying that i need 5A ecu but if its 1.6 cc then i need 4A ecu
So guys kindly tell if i am correct ? Also how can i check by looking on engine that whether its 5A 1.5cc or 4A 1.6cc ? There is no sticker on it
Also ecu harness has grey grip (i dont if that also helps in identifying)

Thanks

Yes bro 4a is 1600cc
While 5a is 1500cc
They r identical engines but there is a little differnce by looking at them

How did he wire up the 6 pin 5afe distributor to a 7afe ecu which requires additional pins?

5afe has no cam sensor and just relies on a 4 pole crank sensor to time the injectors and ignition.

7afe uses the 4afe system with a 4 pole crank sensor and 1 pole cam sensor. Did your mechanic swap out the distributor too

The idle speed is completely ecu controlled, and remains stuck at high rpm unless engine reaches 80c coolant temperature. It will also increase idle rpm if the air leak ports that connect to the power steering pressure switch and ac idle up solenoid are not connected or are leaking.

Brother Can you guide me how to differentiate ?

[shanii89]

I have no idea about the wiring brother
I am planning to visit @rajaatta as 1 bro suggested in reply.
I am hoping that he can check whether any wire or sensor is missing or ecu needs to be changed

In 5afe the corners r little round

[aziz.rehan]

In 4afe they r little different

i think no point to worry as things seems pretty normal.
