I installed an Innovate LC-1 in my KB 02 GT last summer and have two issues I'd like to pass by others for feedback. Background: The car is running the factory H-pipe. I have removed the B2S1 O2 sensor and installed the WB sensor there. I wired the LC-1's Analog 1 output to the factory O2 sensor wiring at the top of the bellhousing and am using it as a narrow-band simulator. Analog 2 feeds my A-pillar mounted WB gauge. I'm confident the wiring is correct and sound but am open to all suggestions... Issue 1: Engine-start procedure or gauge doesn't register If I get into the car I basically need to turn the ignition on but not start the engine and wait for the gauge needle to make a complete sweep (0 to 18 and back to 0). If I start the car then everything seems to work fine. If I start the car while the sweep is in progress, however, the needle will subsequently sit at 0 and not move. If I turn the ignition off, wait a second, and then do the procedure "right" the gauge behaves normally again. Anyone else seen this? Issue 2: B2S1 OBD codes If I allow the engine to idle for a while -- say, a minute or two -- sometimes the SES light comes on. When I pull the codes I get P0174 (system too lean B2) and P1151 (lack of O2 sensor switches on B2S1, bank lean.) This is the input to which I have the LC-1 connected. I hooked up my scanner and took a few screen shots while idling and running it up to 2000RPM. Here's a "closeup" shot of the front O2 sensors for B1 (green) and B2 (blue). This is at hot idle: Here's a shot while holding the engine at 2000RPM in neutral: Here's a couple more "zoomed out". Idle: Holding 2K RPM: You can see that at idle the B2 signal seems to be full of noise and random variations. At 2000RPM, however, it looks much better, much more like the "real" O2 sensor (green.) I've tried programming different time values (instant, 1/12, 1/6 and 1/3-sec) and it doesn't really seem to make a difference to the signal quality. I can't see this being a wiring problem since I wouldn't think that would be RPM sensitive. As well, the WB gauge on the pillar doesn't do anything unexpected. For example, I see no evidence B2 is "lean". At idle the gauge is ~14.5:1 (give or take). It's not like it's constantly above 15:1 or more. Any ideas on this? Anyone else using this analog output in this fashion? Is this perhaps a firmware revision issue?
