Since the PR3 will come with the motor I'm contemplating this because the swap, apparently, will be very easy to do with the zdyne one wire conversion (b16, crx).
only down side is the decision.
Zdyne conv.
pros=very easy swap with stock ecu and one wire. smooth running engine.
cons=price

pr3 chipped/not chipped
pros=designed for the engine, comes with the engine
cons=difficult wire conversion and perhaps possible harness purchase.

I desperately need feedback because I hate spending money and hate extra work but I LOVE doing things RIGHT!

Thanx in advance

 

The wire coversion for the PR3 is 4 wires. It is very simple.
