my buddy is running an earlier ecu on his 97.5(obdII) turbonetics kit and hes having problems with it now. jwt is not the best place there is for the turbo setup but unfortunately, its probably the only place for an altima at the moment. there are various pin-out diagrams on the net that are available and if memory serves me correctly, i have one of them on my computer at home. when i get home later, ill see if i can find that and post it. until then, youre more or less stuck with changing the wires over to run the earlier ecu's that have been reprogrammed by jwt.
