currently have a swapped engine in 98 corolla, was originally 2c engine (2.0d) but swapped with 4afe a/t 1.6 , facing a problem with ecu , have no details on ecu but want to replace. **WHICH ONE IS BEST OR REAL ECU. the cold startup on the car is wayy worse than any carborator engine check the car to electrician all things were set but he said ecu has problem.

Ecu depends upon generation of an engine.
Get wiring properly done.

Like whole wiring refresh ?

Yes, very easy to do.

Sorry hut are you talking about whole wiring out from engine and clearance or just see the connections... One more thing thorttle body and ecu communication has been checked ... Everything is fine but ecu doesnot ask the thorttle to raise rpm when any load is on or in cold start....

One more thing how kuch will the 4afe A/T ecu cost in isb

Yes take the complete engine wiring out. Redo it and put it back.
Have you checked the IACV
Ecu will adjust rpm on electronic load only if ELS pin is connected to load.
Probably 5-7k now.

IACV IS is completely cchecked and is working but the problem is same... Ok will do rewiring soon and will update.. actually our electricians refuse to do this work of rewiring so he said to buy another ecu
