Thread: LM-1 problems
07-21-2008, 08:59 PM #1
I have a new innovative L M-1 AFR meter. It was bought a few months ago NEW and used twice with no problems.
The past 2 weekends i have been trying to recheck AFR readings on RXP to check in hotter temps and Get base numbers before installing headers.
Now the guage will read correct for like 5 seconds and then goes to showing 30 to 40 % AFR. The lambda goes from .94 to like 3 to 5. I even recalabrated the sensor to the instructed 20.9 % showing once you turn it on but still goes to high readings.
Any help or suggestions are aprreciated as i cant install headers without my LM-1 working correct. thanks

After recalibration it will show like 11.8 to 12.4 while engine is idling. Then just goes up to 30 to 40 %
I guess i will call innovative tuners tommorow and ask them for trouble shoot and sounds like will need to get another sensor.

I tried checking the plug wires this weekend or atleast the ones that go to LM-1. They all seemed to be ok. I did not try to recheck the connections to battery but seemed to be working as when you disconnt wire to LM-1 from battery it would show no 12 volt in line sorce, so i figured was getting good connection.
I find it hard to believe that my sensor was hurt as it was used 2 times.
Sucks to have the mods in hand and cant install cause brand new LM-1 want work.

when i did my first bung hole add to a j-pipe i ran through two sensors in 15 minutes and thought i had a LEAK ...........i didnt though.........i take everything apart pressure test the j-pipe to find it doesnt leak as i knew it didnt.....then reinstall with a new sensor and i havent lost one since.....dont know why i burnt two out of the gate but i did then havent burnt one since....if u can shake it and it rattles its junk and may be junk even if it doesnt rattle.......its a Bosch Premium Oxygen Sensor #17014 available at Auto Zone for about $70.00 a pop and they carry 1 year warranty. so save your receipt......good luck!

Sounds like a bad sensor skoepp I like that autozone sells them... easy way to replace it if it goes bad. Too bad there is sensor that works in our ski's that can just be left in it without a problem. Would be cool to have a little digital display showing your AFR always available.
