Quick question...are their any ECU's that are interchangeable with the A box?

 

Negative on that one.

 

Can we ask what you are looking to do? if you have a spare A box and want it chipped for your car you can do that but there are only a few people that can do that.

I have a difference ECU code in my car The guys at VAST performance were able to modify the ecu and the files to work

 

Ya but there isnt a Vast performance place anywhere near me
