benkei Posted March 19, 2011 Share Posted March 19, 2011 After selling the Apexi FC ECU and replacing the stock ECU on my J-spec TT6, the idle hunts around 450-500rpm, and will sometimes stall itself. Also there is a whine from the back of the car, maybe the fuel pump? When driving the car it's fine, although the engine sounds different, more 'meaty' and the exhaust note is deeper too. There doesn't seem to be much of a change in performance, and the stock BOV dosn't make half as much noise as it did before either! Any ideas? Does the car maybe have cams?
