APSX D2 Wideband O2 Air Fuel Ratio (AFR) Complete Controller Gauge Kit (Including LSU 4.2 Oxygen sensor). WHITE Face Plate & Green LED Display (V2 now comes with Anti-Glare Face Design).
APSX Wideband Controller has been designed to exceed the performance of similar devices, while offering lower cost. It is easier to install. When you make modifications on your engine, accurate air/fuel ratio data is so important. Engine runs rich, it can cause a loss in power. Also if it runs lean, it may cause serious engine damage.
Time to shut down your engine before damage occurs. This kit includes: D2 52mm gauge assembly, pre-assembled output and oxygen sensor cables with connectors and Bosch LSU4.2.D2 assembly includes clear lens, black bezel, face plate, bung and LED display. It is smaller and more cost effective than other leading brands in the market today. It comes with benefits such as. 1 Less wiring no D1 controller required. 2 Simple installation no D1 controller required.
3 Bright LED Display and supports Four types of fuel (E85, Diesel, Gasoline and Methanol) and lambda display. 4 - Sweeping LED "needle" indicator from rich (green) then normal (orange) to lean (red). 5 - Fail safe connector - it is not possible to make a wrong connection. 6 - Multiple outputs for digital (to PC), analog (to data logger / EMS), narrow-band for simulation and extra switch options. 7 - No need a PC or tablet for programming upper/lower limits and other settings.
Less Wiring & Simple Installation. Since there is no D1 controller required, there is only Bosch LSU4.2 Wideband Oxygen Sensor (17014) and output cables to be connected. 1 Analog 0-5V linear output for engine management systems (EMS) and data loggers (MegaSquirt).
Lower and upper limits are 9 AFR and 19 AFR (0V = 9 AFR, 5V = 19 AFR). 2 Digital output is 9600 8N1 serial that can be connected to your PC. Both EFI and carburated applications are ok. Soft Start technology protects oxygen sensor for damages. The low and high limits for analog and simulated NB (Narrow-band) can be modified using the setup procedure.APSX D2 has a 4ft output cable (5 cables / green-white-red-orange- black) as shown in diagram above. Red power cable goes to 12V source in your vehicle. Black cable goes to a grounded source such as battery ground (-) post. Green digital output is 9600 8N1 serial that can be connected to your PC. If you want to connect other devices such as data loggers or AFR gauges, you can use white analog cable for 0-5V output.
Orange narrow-band cable is for simulated NB. The sensor cable (8ft) should be routed in a way so that there would not be any contact with the exhaust piping and other extreme heat sources to prevent damage to the wiring. GUIDELINE FOR THE LOCATION OF THE OXYGEN SENSOR.
Weld the bung at least 24 downstream of exhaust port outlet or 24 after the turbocharger. It should always be before the Catalytic Converter. Also it should be before the X or H pipe if there is. Please check your vehicle for exhaust leaks, camshaft overlap and open exhausts because those would cause false lean readings. Not following these directions may result in premature failure of the sensor.
Oxygen sensor can get very hot when powered. Keep the oxygen sensor powered when the engine is running to prevent damage to the O2 sensor. Already Calibrated (Plug & Play Installation). The O2 sensor should be exposed to free air for the first time calibration. Hold the button back of D2, you will see display unit counting from 1.1 to 1.6.Hold the button until you see 1.6 blinks and release it to complete the calibration. This should take less than 60 seconds. Once it calibrated, display reads 19.0. You can now connect the O2 Sensor onto the exhaust pipe. See the guidelines on the left. For the factory settings, disconnect power, hold the switch while turning the power on and wait for 3 blinks.
You should re-calibrate after this action. Calibrated for the enclosed sensor. For the Calibration Video please visit "widebandapsx" at our official YouTube account. Please perform a bench test before contacting with us. Please also use the battery as your ground source with an 5A fuse to be on the safe side.
If you are having 8.88 reading problem, there might be a discontinuity on your chassis and can not be used for grounding. Place all parts of the kit on a bench/table. Make connections by using a reliable 12V battery or other power source.
Check the display to see if it shows logical outputs while you place the oxygen sensor into a gas soaked towel or paper towel. You can even use a lighter gas. Readings should change between 9 and 19 AFR. If not, please send us the unit for inspection to repair or replace. Depending on when you release the button on D2 after holding it, you can modify different settings.
1 Set the fuel type (1-Lambda, 2-E85, 3-Gasoline, 4-Diesel, 5-Methanol). See the chart and table above for fuel types. 2 Set NB lower limit. 3 Set NB upper limit. 4 Set Analog lower limit (Range 7-25 AFR/Default is 9 AFR).
5 Set Analog upper limit (Range 15-25AFR/Default is 19AFR). 6 Calibration (Calibration range we have seen among the Bosch LSU4.2 sensors 70-130). 14.7 AFR or Stoich: Cruising or on Neutral gear.19 AFR or Max range: On gear and gas pedal is not pushed.
