Innovate Technology Releases LM-1 at SEMA 2003
Affordably priced, the LM-1 is the first fully-digital air/fuel
ratio meter for the professional and the enthusiast alike.
SAN JUAN CAPISTRANO, CA, November 3, 2003– Innovate Technology,
INC. today announced the release of the LM-1, the world’s
first fully-digital air/fuel ratio meter. In a major advance
for engine tuners, the LM-1 enables precise measurement of exhaust
air/fuel ratio (AFR) at an affordable price. The meter’s
digital signal processing technology provides data on exactly
how rich or lean an engine is running at any load. The LM-1’s
self-calibrating circuitry also compensates for changes in temperature,
altitude, and sensor condition.
Tuning an engine for maximum power previously required long
trial-and-error sessions on a dynamometer. With the LM-1, precise
AFR measurement allows the user to correctly adjust many variables-
including carburetor jetting, fuel injection, turbo fuel curves,
etc.- without long and expensive dyno sessions.
Another key feature of the LM-1 is its ability to capture and
log up to 44 minutes of AFR data, 12 times per second, in multiple
sessions. This data can be quickly downloaded into a PC via the
included serial cable, viewed, and analyzed via the included
software or any standard spreadsheet program. And with the available
auxiliary-input cable, the user can capture and log up to five
additional inputs (RPM, MAF, MAP, TPI, etc.). Thus the LM-1 can
serve as a completely integrated engine tuning workshop.
“We often see people make expensive modifications to their
engines, only to lose horsepower after installation,” says
Klaus Allmendinger, Innovate’s VP of Engineering. “The
key to tuning is accurate measurement of results, and the key
to accurate measurement is the LM-1.”
Competing air-fuel-ratio meters vary widely in their precision,
price and portability. The best ones are in the $3-$5,000 range,
are designed as lab-grade instruments for big operations, and
require careful and regular calibration. They are, however, no
more accurate than the LM-1. In fact, because of calibration
problems, in many cases expensive analog meters are less precise
than the LM-1’s 0.01? accuracy specification.
On the other end of the spectrum, low-cost analog AFR meters
in the sub-$500 range typically use a standard, narrow-band oxygen
sensor and are therefore only able to tell whether the fueling
is rich or lean but not by how much. These types of meters are
therefore of limited value for engine tuning.
“There’s a lot of technology in this device,” states
Patrick Thompson, Innovate’s President, “but we’ve
made every effort to keep the price as low as possible to make
it affordable for everyone. Now your average enthusiast can measure,
analyze, and tune as precisely as a big racing team.”
The standard LM-1 includes a Bosch wide-band oxygen sensor and
cable, cigarette-lighter adapter, serial cable for PC connection,
9V battery, exhaust bung and plug, CD and manual. Available accessories
include auxiliary input cables, battery-clip power cable, exhaust
clamp, and analog output cable. Additional accessories include
an RPM converter input cable, dash-mountable displays, and AC
adapter. The LM-1 ships with a Bosch sensor, however, it can
also function with other wide-band sensors, including Honda/NTK
and VW sensors.
The LM-1 sells for a retail price of $349. Contact Innovate Technologies at (949) 388-4442 or visit www.tuneyourengine.com for more information.
