I have a Honda Civic 01 and I have a problem with my ECU fried told me that I got to replace this but when I went to install it I saw that the current model are different installed in my car is 37820-PLM-A53 and I replacement got 37820-PLM-A72.

There will be some inconvenience with this ECU or the same??

 

Your still using a PLM, which will be fine. But, you will need to have a Honda dealership match your keys to the immobilizer regardless of which ECU you use.

 

So no matter what the model is A53 or A72 will work with my car?

 

Its going to need a reflash to match the immobilizer ring, but yes it should work.
