ECU Swap

[jtrikakis]

I have a 91 with a stock ECU. I got my hands on SOS Hot Chipped ECU for a 91-94 NSX. Do I just swap units, or are there other steps I need to do to take this work? Yes, I've done a bunch of searches, but I haven't found anything telling people to perform certain steps. Thanks. - Jim Trikakis

It's weird to run unknown firmware tuned on unknown engine with unknown mods.

It's not something I would do without a dyno and making sure the a/f ratios are in a safe range and/or you are actually getting positive results.

But to answer your question, if it's a full blown ecu, just plug and play.

I called SOS and yes plug and play. I know about the motor that ECU once serviced so that's covered. The dyno sounds like a smart idea. Thanks.
