Using ODB1 ECU on 3.2L engine

[ak]

Hey guys, from the search, it looks like you can swap in the 3.2L engine into 91-94 as long as you keep the intake manifold, injectors, coils, ECU and wiring harness. My question is, has anyone done this and if so, does the ECU need any modification or does it run with the stock ECU without any issue? Would there be any issue with idle, a/f, emissions etc?

You can definitely do the 3.2L engine with a 91-94 ECU. We've done two setups now with 3.2L factory engines in early NSX, and the cars perform well.
