Innovate Motorsports LM-2 Air/Fuel Meter Wideband Air Fuel Ratio Install & Test

August 29, 2019


Bucko: The thing about a performance car is
when you start to modify it you’ve got to make sure it’s tuned correctly. I don’t care
if you’ve got a Hemi, or a Mustang, a C6, or even a 9-second drag car. Your air/fuel
ratio is the difference between top performance and your engine blowing up. Today, we’re going
to show you the latest in wideband controllers from Innovate Motorsports. And when you check
out all its features, it’s going to blow you away. Welcome back to the PowerTV Garage. Today,
we’re giving you an inside look into the LM-2 from Innovate. It’s a fully digital wideband
controller that does everything but tune your car. We’re a bit concerned about our Hemi
supercharged Magnum back here, because we added some parts, and we’re worried it might
be running a little bit lean. BJ: We’re going to give you a preview of the
LM-2 to help you decide whether this is the right meter for you and at the same time,
see if our Magnum is running rich or just right. The LM-2 is unique because it features
three capabilities in one. A wideband air/fuel ratio meter that features lightning fast reaction
times, a full OBD-II scanner that reads and clears trouble codes, and a full-feature data
logger than can display log runs on both the device’s screen as well as through the LogWorks
software. Bucko: As you can see, we’ve got the LM-2
installed and configured. What I’m holding here is the LM-2 handheld device. It’s a multi-function
device, as you can see. The large LCD high contrast screen. These six buttons here make
it very simple to use, so easy that even I can use it. So let’s take a quick look at
the install. Following the instructions, first we welded the bung into our exhaust, upstream
from the catalytic converter, and screwed in the supplied Bosch sensor. Power for the
LM-2 comes from the cigarette lighter. The OBD-II cable plugs directly into your factory
OBD-II connector. And finally, we hooked up our RPM input signal,
which can be fed from the coiled ECU injector or ignition box. Of course, there are a bunch
of options with the LM-2, such as hooking up one of the four fully differential analog
inputs for logging things like boost or real speed, if desired. Finally, we decided not
to use an external gauge, instead using the LM-2 handheld screen itself. Now that we’ve
shown you the install, let’s take a look at the Innovate LM-2 in action. Most people who are going to buy the LM-2
are going to do so because it’s one of the best air/fuel meters on the market. Innovate
Motorsports claims that it’s fastest and the most accurate. The Innovate LM-2 lets you
record a run either on the street, at the track, or on the dyno, just by pressing the
record button. You can see the LM-2 screen will inverse. It will display a little ‘r’
in the status bar down at the bottom. If I want to stop the recording session, I just
simply press the record button again, and we’ve got the whole run saved. So let’s head
back to the shop and see how we went. Okay, check out how easy this thing is to
use. To check out my acceleration run, all I have to do is hit mode, then enter. You
can see the acceleration run playing over time. Now, this is great because, basically,
I’m getting full access to what my air/fuel ratio is doing, and I don’t have to look at
a gauge. Another cool thing on this system with the controller is they’ll let you toggle
between one and two channel operation. It’s also a line graph for dark channels and a
fuel graph. But this is just another cool thing to show off to your buddies. BJ: As an ASE certified mechanic, I know how
important the OBD-II onboard diagnostics are for troubleshooting. The LM-2 gives us the
ability to read up to 16 channels from the UCU and record it to an SD card. Not only
can we troubleshoot with the LM-2, but we can get valuable data from the sensors, like
coolant temp, spark advance, and air inlet temp. And then you can cross-reference this
against the air/fuel and RPM in the LogWorks software. Bucko: While BJ’s been up the front working
on that, we’ve been down here going through the setup processes. It’s a pretty simple
affair, really. The first thing we had to do was configure the channels that we want
on the configuration screen. And we’ve chosen four. We’ve got the O2 sensor up here. We’ve
got RPM sensor, spark advance, and a map sensor, as well, to measure the boost levels. Now,
check out the log trace of the OBD-II data. You’ll want to reference your LM-2 instructions
here, because the logging capability of the LM-2 allows it to really be a powerful resource. Now, we also discussed reading and clearing
DTC codes or trouble codes. This is as simple as choosing OBD-II on the menu and selecting
“get DTCs.” If there are any error codes, that will be displayed. To clear them, it’s
as simple as choosing “clear DTC codes.” BJ: And that gives us a full OBD-II scanner
in our wideband for no extra dough. Bucko: The guys at Innovate have got a complete
step-by-step manual on how to do LogWorks. But, in essence, the way it works is it allows
you to review your data either by time or RPM on any Windows-based computer. Now, rather
than going into all the capabilities of this system, what we want to do is show you a few
screenshots of how you can review your data from a log run, including the OBD-II parameters.
Now this is typically the kind of depth that you’d see on a $2000 data logger, but not
anymore. Now, hopefully, you understand a little bit
more of what the LM-2 is capable of. What you probably don’t understand is that this
little handheld device costs under $500. Up until five or six years ago, to get the kind
of data that we’ve seen here today would have cost over $4000 in data logging equipment
and wideband equipment to get what we’ve seen here today. So thanks to LM-2, we’ve now got
a 5.7 liter Vortec-equipped Magnum that’s tuned for maximum horsepower and runs a very
safe air/fuel ratio. Till next time, my name is Bucko. Thanks for watching PowerTV.
