what ecu would you swap it out for? the suv it came out of? no you dont need to swap the ecu. the motors are pretty much the same and shouldnt make much of a difference.
Use the same ECU but change any sensors on it to OBD1. Use your LS intake manifold.

Great to hear that then.
The reason behind using the LS manifold ( if you didn't already know ) is the B20 manifold is way too tall.
@bacon Purchased a b20b from JEI with a lower manifold .. so it should be the same.
