A wideband UEGO sensor controller accurately monitors Air/Fuel ratios (AFR) during the tuning process to prevent a lean fuel mixture, which could lead to engine damage. AEM has combined its single-channel wideband UEGO controller and gauge display into one unit, uniting unsurpassed AFR accuracy and control with an easy-to-read interface. AEMâs Gauge-Type Wideband UEGO Controller features a digital LED display and sweeping LED âneedleâ that changes colors as AFR changes from rich to lean. The unitâs 52mm (2-1/16â) gauge housing fits in most gauge pods and can be remotely mounted virtually anywhere.
Ideal AFR monitoring tool for EFI and carbureted applications, and engine dynamometers
Does not oscillate AFR reading like narrow band sensors
No laptop required for monitoring!
Bosch sensor included
Accurate to 0.1 AFR
Reads in AFR or Lambda via a switch in back of gauge housing
24 Color-coded LED display lights provide immediate reference to engineâs air/fuel ratio (AFR) or Lambda ratio
Integrated three-digit display reveals AFR or Lambda in real time
User-programmable 0-5v analog output included for use with data loggers and virtually any engine management system
Serial data stream included for output of AFR (RS 232)
Customer Reviews: Great product , fast shipping and easy installationMay 4, 2010 Alex Bond 1 out of 1 found this review helpful
AEM 30-4100 UEGO was very easy to install. I had it up and running in no time and also made a RS232 wire as well as a Firewire IEEE 1394 (male to male) for dataloging. The RS232 was connected to a Hyper Terminal program found in Windows Xp(Only optional and was used to double check my formula in Live Link..I did not datalog by using both cable at the same time) . The IEEE 1394 cable was connected to a Xcal3 from SCT and used with Live Link to datalog more efficient. I hooked up the 12v cable for the gauge on a 12v ignition only wire on the car and a ground under the dash. Simple as that. Also has lights integrated in the 12v and ground circuit so you don't have to mess with also hooking up the lights as in other gauges. Only downside is the Bosch O2 sensor ,which I have heard that they go bad pretty quick , especially if your car is running to rich .The cost for it is about $60.
