um for what car/engine

I am trying to install a Apexi turbo timer and when i followed this diagram that you have had to have windows translate it. But when i hooked the white wire the front oxygen sensor to b134 33 the 02 sensor did not work I checked the pin placement on how they are all lined up they all matched but i sooned realized that the jdm model is a different ecu same setup and everything. But I have the a different model number then this one. And if anyone has a ignition diagram that would be helpful too thanks

I think the turbo timer O2 readout is meant for narrow band sensors only

MDTURBO 05-14-2006 02:10 PM

^^ Correct... narrow band 0-1v, ours is 1-3v

thanks alot for that info very helpful. just need a ignition diagram and thats about it. My buddy and I hooked it up the other night and when I started it it was fine but when i pushed in the clutch it made a grinding noise which is obviously not good for my car lol but did not do any damage thank God so pretty much we just ungrounded the wire so it would stay off. thanks guys
