Innovate LC-1 Wideband Problem

[marcman804]

I just installed the LC-1 wideband on my car using the included instructions. I installed it in place of the second o2 sensor. I calibrated it and then started the car but it will not read pass 10.3. When I first start my car it blinks at 7.4 and then it jumps to 10.3 and stays there, even when I rev the car a little it stays the same. When the car is off and the key is in the on position its reading the same thing. This is how I installed it...
Brown - ECU Pin 76
Red - Accessory power supply
Blue + White - Grounded at same spot on chassis
Black - wired up for the calibration button

I am also wondering about this. I just got an AEM Wideband Uego
AEM AIR FUEL DIGITAL WIDEBAND O2 UEGO CONTROLLER GAUGE 6-IN-1 30-4100 FREE SHIP (840879013417) | eBay

and I read in this thread http://www.dsmtuners.com/forums/bolt-tech/34954-truth-about-exshaust-ground-strap-2.html that Violater101 put his wideband in the 2nd o2 sensor and used dsmlink to disable the 2nd o2 sensor.

I was planning on doing that too. When I get my dsmlink.

Anyone else do this? Is there any reason not to disable the 2nd o2 sensor and put the wideband there?

I snipped the wire from the rear O2 and use it to log the wideband. No issues so far other than (obviously) Link picks up a CEL from the rear O2 being non-functioning. The front O2 is what the ECU reads for fuel trim, not the rear. It's rather pointless if you ask me, especially if you live in a city that doesn't do emissions testing like mine.

Version Check: Please take note of the version of LM Programmer shown in the screenshots. There are newer versions (v3.19 and 3.27) that are shipping with the units that Innovate knows does not function as it should. For some reason, they do not mention this anywhere. The easiest way to determine if the version you have works is to make the changes below, click the Program button, and then go back in and see if the settings were retained. The most recent version does not hold your changes. The latest known working version is v3.15. Until Innovate provides a fix for this, you can download the older v3.15 software here:

Blue + White - Grounded at same spot on chassis

It's a minor point that won't address the larger problem you're having, but we actually recommend running the white wire to sensor ground and the blue wire to chassis ground.

Also there has been issue with the Version 1.10 on the Lamda cable itself. You need to down grade to Version 1.00. That may fix the issue ## having. I dont remember where I got the firmware file but I do believe it was off innovatives website. It took a few mins of searching to find it for me

It ended up being bad wiring, I had a buddy of mine help me with the install and he had the yellow wire connected to the ECU instead of the brown. I swapped the wires and recalibrated it and everything works perfect now. Im not exactly sure how accurate it is in place of the rear o2 though. Does anyone have any info on this?

Accurate as in reading the same A/F ratio as if it were in the front O2 location? That's certainly fine. The air to fuel ratio isn't changing between those two points unless you have an exhaust leak.

Being installed in the rear O2 will, however, introduce a delay in the reading just due to its increased distance from the engine (compared to the front O2). This delay can be pretty significant at low airflow (idle). At WOT, not so much. At idle, I think I've seen as much as a 0.8 second delay. Doesn't sound like much unless you try to run closed loop fuel control off that sensor. Then the delay will drive you nuts. We have a little more info at the bottom of our narrowband sim page.

Oh ok thanks for that info. I had intended to place it in the front o2 but was told not to because it would kill the life of the o2 sensor.

Hit the nail on the head there. win
