p72 ecu with b16

[aso]

hello
a friends and i recently picked up a 92 honda civic 4 door with a b16A swap.
the car come with a p28 ecu in it but it didnt appear chipped so we got a p72 ecu to put in it. now the car is running rich and i dont know why? also is it hard to install a knock sensor in the block? any help is appreciated thanks

p72 is for a gsr

you dont want a ecu thats been chipped with some random program, they usually cause more trouble than they are worth. either stick with a stock ecu or get dyno tuned

i know a p72 is for a gsr but we swapped em because the p28 is for a single cam. we figured that switching to a ecu thats made for a dual cam i was just asking if becuase its a gsr would it make the motor run rich?
