im really new to the honda game but not cars so i am mechanically incline. i bought a an 00 civic si with an h22a4 swap. when i checked the car is still running p2t civic si ecu... i want to change it but dont know what is the correct way to setup this car... please any info will help. thank you

 

Why don't you mention the code it's throwing? Why is it not running the correct ECU if the swap was done correctly? It should be running a P13 if I read that correctly.
