dounome Posted May 20, 2006 Report Share Posted May 20, 2006 Im hooking up a LM1 tomorrow and will be using it as a narrowband also. Well to do this I believe I have to route the analog wires to the O2 sensor Im taking out. Red analog wire to the sensor and bare wire to sensor ground. Just looking for a little insight to this process or point me in the right direction for the installation. Thanks Quote Link to comment Share on other sites More sharing options...
dounome Posted May 20, 2006 Author Report Share Posted May 20, 2006 If you have the LM1 and are using it as a narrowband also please pm me. I have questions about the O2 sensor wiring colors. I have no idea what color on my anolog harness goes to what. Thanks Quote Link to comment Share on other sites More sharing options...
zippy Posted May 21, 2006 Report Share Posted May 21, 2006 I've never seen anyone use it as a narrow band. Why would you want to do that? Quote Link to comment Share on other sites More sharing options...
cadowns Posted May 21, 2006 Report Share Posted May 21, 2006 Check this old post LM1 Post Others have done it with help from the efi Forum. CD Quote Link to comment Share on other sites More sharing options...
Holty Posted May 21, 2006 Report Share Posted May 21, 2006 zippy, he is wanting to use his LM-1 WB 02 sensor to log WB data, and simulate a NB sensor so he dosn't have to add a new bung in his exhaust. don't know if this is what your talking about, but you can check this link and it should give you ALL the answers you need. I know you are wiring a LM-1, but the LC-1 wires basically the exact same way. http://www.hptuners.com/forum/showthread.php?t=2947 Quote Link to comment Share on other sites More sharing options...

Thanks <{POST_SNAPBACK}> You've got big balls using narrowbands with FI... just put the truck in OL and take out your NB to insert the WB Edited May 21, 2006 by MN C5 (see edit history) Quote Link to comment Share on other sites More sharing options...
dounome Posted May 21, 2006 Author Report Share Posted May 21, 2006 I have the WB sensor installed and I have the LM-1 reading the AFR fine. BUT I couldn't wire up the anolog harness for the LM-1 because I have no idea what wires to tap into on the factory O2 harness? Quote Link to comment Share on other sites More sharing options...
dounome Posted May 21, 2006 Author Report Share Posted May 21, 2006 Thanks Holty. I put the sensor into passenger side foward location. And yes I did this to avoid putting in a new bung. My problem is I have no idea what wire to tap into for sensor power and sensor ground, for the anolog 3 wire harness on the LM-1. I did check out that link and it only talks about the rear style connector which is shaped like a box, where the front connector's are shaped like a triangle. I have 2 black wires, 1 white, 1 blue. Can anyone tell what is what. 1. heater 12V 2. heater ground 3. sensor pwr 4. sensor ground Quote Link to comment Share on other sites More sharing options...
BenKey Posted May 21, 2006 Report Share Posted May 21, 2006 I still don't get wanting to do this just to avoid paying someone $25 to place another bung in. Quote Link to comment Share on other sites More sharing options...
dounome Posted May 21, 2006 Author Report Share Posted May 21, 2006 Well in that case Ben if you think I should not do this then I won't! Come on man is this all you have to do. If you really don't have the answer to the problem then mind your business. Quote Link to comment Share on other sites More sharing options...

Your LM-1 only has 3 wires? If you could explain a little more, i might be able to make some suggestions. Quote Link to comment Share on other sites More sharing options...
dounome Posted May 22, 2006 Author Report Share Posted May 22, 2006 Holty thanks man. I did get it figured out today. I needed to know which of the 4 wires on the factory sensor was sensor signal and sensor ground. You need to hook up the red wire from the LM-1 anolog harness to the sensor signal and the bare wire to the sensor ground. I found out what was what. Just incase anyone else needs this info. Blue=sensor signal, White=sensor ground, 2 blacks= heater ground and power. I have noticed that my sensor I replaced is real lazy now on the scanner. Someone said something about changing the voltage on LM-1 anolog tabs in the program? I have no idea what to change them to. Bank 1 is switching just as it was before the install and now bank 2 (WB sensor) switching slow. Quote Link to comment Share on other sites More sharing options...
