Hi Idrees, Sorry for the topic bump - late answer, I've got a 4E-FTE that came out of of a black EP8x automatic frontcut. Right after the conversion, I drove(?) a manual transmission (also EP8x ECU). When I was doing some stuff at a local garage from a friend, we hooked the Corolla (yes, not a Starlet) up to check the emission figures, and we discovered that the engine was running WAY to rich. It would also NOT pas the dutch version of MOT. I could feel that after placing the 'automatic' ECU it picked up much better. MOT emission figures where excellent after that! Instead of running 10 kilometres on 1L with the wrong ECU, I can get 13 kilometres on the good ECU if I control my right foot by the way, I had a special wiring loom made to connect the first wiring loom to the automatic ECU. A 'converter' . When removing that second loom I can drive with the manual ECU. Cheers, Marco.
