I have asked this question before. What ecu should I use for a LSVTEC setup. It seemed as if I should use the b16a ecu. The only problem with it is that it would make my car run a little lean. Can I get a Fuel Pressure Regulator and turn up the pressure to fix the problem. Another idea I had was to have katman reprogram my ecu for ls vtec. Its like 175 I think from him. What do you guys think?
