I am about to put a 4.0L in to my 3.9L NC Fairlane and i was wondering do i have to use a EB computer for the log manifold . Or can i still use my 3.9L computer . Or if i use a EL manifold & EL ecu will i have issues with me climate control i know that i have to run wires and change ecu pins for the EL ecu. Any info would be good

Cheers Rick
