I keep reading about if a p28 ecu is used with a GSR it won't control the secondaries of the intake manifold and will not be able to use the IABs. I am not knowledgable of these things. I am doing a LS/VTEC using a B16 head and intake. Do I need to be concerned about those things? What is IABs?


Also, can an automatic p28 ecu be chipped?

How can I find out what the rpm vtec engagement is and what the rev limit is on a p28 from the factory? Is it the same for an auto and stick?
