Hiya,
Just got done getting an Innovative Motorsports LM-1 Lambda Meter installed (with some help from Mac Autosport :) ).Â* Turned out to be a lot easier than I had anticipated - actually I could almost swear :mitsu: anticipated this, hehe.Â* The exhaust I'm using is a [forum-restricted] Signature Series, but this procedure should work for most Evo exhausts.Â* Here's basically what we had to do:
1. Weld the O2 bung to the end of the downpipe, basically mounting it right before the cat (which is where Innovative recommends it to be placed on a turbo car) and on top of the downpipe.Â* Again, Innovative recommends that the O2 sensor be mounted above a horizontal plane, so I figure that mounting it vertically is perfect :D
2. Removed a rubber grommet located right above where the O2 sensor will mount.Â* This opened up a passage right into the passenger-side footwell, terminating behind the center divider (I'll take a pic of the location later).
3. Mount the exhaust
4. Drop the O2 sensor down from inside the car (you may or may not have to make the existing hole larger).Â* We ended up making the hole slightly larger on mine ... at 9pm we just didn't have the patience to try to fit it through the existing hole.
5. Screw the O2 sensor into the bung.
As it stands, the cable from the O2 sensor is exactly long enough to terminate right next to the glove box behind the dash.Â* So far the LM-1 seems to be very accurate.Â* On my dyno runs, I was using it to compare the AF readings of the dyno vs. the LM-1 and it looked right on.Â* However I won't be able to tell exactly how accurate it is until I figure out how to get the logs into my computer and read them, hehe.Â* I guess it's time to RTFM :p
