so i just bought a 93 civic ex coupe and its got 4 wheel disk brakes and 4 wheel abs. its also got a dual cam obd1 zc, however its still got a p28 ecu. doe anyone know if changing to a pm7 or pg7 ecu will affect the abs? and if so how it would affect it?
any answers are much appreciated and thanks for reading!

 

abs has a separate module.

 

do the modules need to communicate with one another or does the abs module just collect data directly from the wheel speed sensors?

 

everything will work just fine
