7A-FE Swap (Manual Engine With Auto Transmission)

[love_ads2002]

Dear Group members, i am facing an issue regarding an engine swap.

i swapped the stock 1.3L carp engine with 7A-FE, The issue raised when i opted for an atomatic transmission and there was no engine available with auto tranny. the mechanic coupled an auto transmission with a manual engine. the engine is run by a manual ECU while gear is automatic. Due to this the fuel average is not getting above 5.5KM per Litre in city.

please guide me through how to install an Auto ECU on this engine and will the ECU replacement resolve the fuel average issue.

please note that i have tried all the possible thing like changing the MAP, O2 Sensor and tunning and even changed the spark plugs to 2 earthing point one's but all effort in vain.

Just get auto ecu and wiring. To get maximum out of your engine. Between don't expect too much.
