ive got an lm-1 and it has built in narrow band simulation via an analog output. innovatives instructions say to connect output 1 to the purple (o2 + signal) and to leave the rest unhooked. i tried this and scanning in freescan the voltage just hangs out around .45x volts while idleing with a warm engine. i tried connecting the ground and it pegs out at 1.0x volts. anyone successfully used an lm-1 to send narrowband signal to the pcm?
