ok guys i just did my gsr swap and i am using a p73 ecu thats integra type r ecu for some reason when i am driving my car it feels like the timiing is retarded on it the car feels major sluggish but when it hits past 3 thousand it feels easys but when i swiched ecu to a jdm b18c ecu it ran just fine could the timing needed to be advance since the type r's have more aggressive cams and cam gears

 

try advancing the timing with the p73 and see what happens.

 

get a p28 if you can its better
