Hi Guys I'm trying to figure out an installation on a Unit thats called VART from company called Swoosh (Overseas) and basically what this unit does is enables you to Control Vtec , get A/F readings., RPM a bit liek other existing units on the Market. I have installed it and cannot seem to get the VTEC thing going. I have attached the wiring diagram of the UNIT if somebody can help i would appreciate it. I only have a problem with VTEC everything else is fine. The VTEC WIre should be Green/Yellow on ECU , I plugged it like Diagram on the Left and doesn't work properly, tried Diagram right with Vtec pressure switch wire and vtec Solenoid Wire still no results check engines lights up . i reconfigured everything back to original and it works like usual. If you experienced an install of this type of Unit or have an idea on how to wire the VTEC please let me know ThanksMy Webpage
