5.2 to 5.9 ecu

[RatRodDesoto]

is the ecu for the 5.2 the same as the ecu for a 5.9 in an 01 dodge ram? the 5.9 block would be coming from a 95 dodge ram. the magnum heads and everything else should fit on either right? and the engine should run standing alone one the ecu right? any tips or answers to these questions should help a lot i'm doing the swap in a few months after i rebuild the bottom end. thanks in advance
