i have a 96 ek with a h22 swap. i am using a p72 ecu out of a gsr. do i need to get this chipped or will it run the h22 without chipping it. they are both dual cam vtec and have iab's so i was told that this ecu could run this engine but i want to be 100% sure. thanks for all the help. merry christmas

 

It will not run properly with the stock P72. You will need to get it chipped with correct H22 maps.

 

^ Im with him. If it runs it will run all ****.
