Finally got my ECU in today and it worked!!! It was a P0H-L61 ECU from a 96 EX. VTEC is popping now, and the engine is running smoother overall! Now to tackle that darn throttle bracket...

 

Your impressions of the F23? It feels like quite a lot more torque along with some increased top-end to me, but that may just be the butt dyno talking.

 

It definitely has a bit more top end power than the F22. It just pulls a little stronger overall! It's a great engine, I'm very happy with the choice I made for this engine swap. If anyone is looking for a good DD engine for a 5th gen, get the JDM F23!
