Thanks for the answers to my "VX engine not performing", my engine is a Japanese VTEC-E (D15B block & P07 heads). I know I have the wrong exhaust manifold (4 into 2), and 4 wire O2 sensor. Now I need to know about the ECU, I have a P08, it seems from everything I read yesterday that I should have a P07, can anyone confirm that? I really want to get the great mileage this engine's known for, but I need the right parts because I'm not getting great mileage now!
