I highly recommend staying away from the LC-1 and going with the AEM UEGO instead. The LC-1 has some serious reliability problems and it's unnecessarily complicated to wire. I've now owned two and when they worked, they worked great and read over a wider range than the AEM and I think it was more responsive as well. However, given the reliability problems, I am not willing to give them a third try. The AEM installed in a fraction of the time (VERY simple wiring), really isn't any more expensive these days, and I prefer the gauge layout over the cheap DB gauge option on the innovate. Both my LC-1s were located on the battery tray as well. That's just my 2 cents now that's I've owned in excess of $600 of wideband gear.

I use an AEM controller and can't complain. I deleted my stock o2 sensor and use it's 4 pin harness to wire my sensor in. Megasquirt reads the controller perfectly and can tune in failsafes incase the car runs too lean1989 325i LS Swap (Money Pit):https://www.r3vlimited.com/board/sho...d.php?t=244933

Hi,
i have got an Innovate MTX-L wideband o2 sensor.
Like this: http://www.innovatemotorsports.com/products/MTXL.php
The difference to the LC-1 is that it has only one ground wire instead oft two like the LC-1.
Can someone tell me how i connect this thing correctly to my e30 ?
Thx

Probably. That was a trick we used on after cat 02 sensors when we removed the cats to fool the computer to make it stop throwing CELS back in my vdub days.Your signature picture has been removed since it contained the Photobucket "upgrade your account" image.

In a day or so my install will be done, so I wanted to update this thread with my experience from a beginner's perspective.
I've made my harness plug and play except for the ground at the latch bolt. it was simple, and I'd recommend doing it every install because you can't hurt the harness in the car this way! I used the pigtail from the old o2 and wired the pushbutton and led inline where it will sit in either the glovebox, the battery tray, or under the firewall wiring cover. I have not decided yet, whatever is most practical when I've routed the cabling.
When I modded the relay for the heater, I just used the soldering iron to plastic weld the cover back on it, I feel like it will be more durable in the elements this way.
P.S. WOW, the stock o2 sensor was a SOB to remove.sigpic

Im a bit confused at the part where it says to jump the fp relay to the o2 relay. Do you leave them connected to the relays? Or splice the two wires together leaving them ALSO connected to the relays? Also curious wich relay is the 02 relay? Asumming its the one immediately next to the fp relay.. the wiring coloring is not the same in a 91 325ix.
