None of these piggybacks have any control of any systems besides fuel and timing. The iVtec on our cars is more complex than any other vtec system honda makes. You would need a stand alone management or Vmanage to control Vtec and cams. But if you have the money and patients and the knowledge you can control vtec and stuff with the Vmanage. You just need to hardwire it in.

The F/IC is a better unit than the Emanage Ultimate for our cars. It works better for some reason. There is a minor flaw in the Emanage firmware in sudden WOT changes. When you go to WOT quickly it dumps too much fuel when you jump to to large of an injector over stock. If you go from the stock injectors to say something like a 550 or higher it will be hard to tune that problem out. Unless you disconnect your primary O2 sensor and tune straight from the Emanage pressure sensor.

The F/IC has a built in pressure sensor in the unit itself and it uses a better method for controlling timing than the Emanage. From what I've been told. But I could be wrong about this part. Hey Mike, chime in here and let me know if this is correct.
