Alright Mikey, I understand this thing can control the RPM that the T-VIS platers open, BUT, can it be programmed to vary the AFM siganl?? Opening the T-VIS 1,000 RPM early doesn't increase the power because the fuel and timing curves remain the same. Can the stamp trick the computer into changing the fuel and timing? Say at 3,500 RPM change the AFM signal by a certain percentage, and at the stock T-VIS opening(4,400 RPM), turn off and return to the stock parameters. Maybe work with the inlet air or water temp sensor? Change the timing with the NE signal? Will it work with the signal voltage of the US spec ECU? Remember, the problem with the S-AFC is that our ECUs here work on a different voltage signal. I believe the JDM work on a 5v signal and ours work on a 9v signal. Just something to consider.
