I have purchased a halfcut from Japan of VR4 RS "CYCLONE" engine and swaped that with my Australian stock VR4 engine.

Will I get any improvement by replacing the original ECU with the Cyclone ECU from Japan?

I know this probably doesnt matter but the Greedy piggyback system is a betterway to go all together, then with just a palmpilot you can monitor your systems as you build your engine, knock sensor, engine timing, air/fuel... and even one better the standalone ems try it out.
