Mp9 exu

Post by Saf1 »

Hi. I changed my 1.4i agy Polo engine to 1.6i afx engine. Do I need to change the ECU as well. Car moves well when cold but has surge/fish bite when under load and at three quarter acceleration. Picks up power when throttle is flat down. Fuels pressure is at 3bars. Any help would be appreciated. Thanks
