Spartan 2 Dual Wideband Gauge Kit 52mm & Bosch 4.9 Sensors

$419.00 $446.95
  • Product Code: Spartan-2-Dual-52mm-Bosch
  • Availability: In Stock

Here we have our dual wideband gauge kit made up of two Spartan 2 wideband controllers, 2x genuine Bosch 4.9 02 sensors and our 52mm dual air fuel ratio wideband gauge which will give you readouts for each Spartan 2 controller on a single gauge. These are used in applications where you have a v6 or v8 and want to measure the air fuel ratios on each runner from the motor, just to make sure both sides of the motor are running the same air fuel ratios. These kits can be used on both fuel injected & also carburetor vehicles.

The 52mm LED gauges are simple yet clear and easy to read and scale 10-20 AFR, each input is clearly marked as A & B, the blue LED’s are bright enough to see clearly during the day and won’t blind you at night. These are without a doubt the best value dual wideband gauge packages around, but don’t let the price fool you, these are an extremely tough, accurate and reliable dual wideband gauge setup.

If you are looking for not only a quality dual wideband gauge package, but a reasonably priced one as well then look no further, as these are it. 14point7 in our opinion make some of the very best wideband products out there, and is why we are proud official resellers for them here in Australia, they are tough and reliable, incredibly accurate and all round just terrific little widebands. On top of this, they manage to do it keeping the cost of their products at extremely reasonable prices, no big name taxes here, just good down to earth widebands.

14point7 have been around for a long time, but some of you might not have heard of them before. This is because unlike Innovate & AEM who are very large companies, 14point7 catered more to the tech savvy DIY car people out there, they also more targeted the aftermarket ECU community of the Megasquirt which isn’t huge here in Australia. Don’t be fooled by the lower price, the Spartan 2 is one mean little wideband controller, it can hold its own against the big guys and in most area’s that matter outperform them.

Where this Spartan 2 dual wideband gauge kit differs from the bigger name brands is it doesn’t come with a whole bunch of features that most people won’t use. Like Innovates logging system, most of us have aftermarket ECU’s and we don’t need extra logging, it’s just wasted tech that adds to the price tag and more components that could eventually fail. The 14point7 Spartan 2 is just a wideband controller, and a bloody great one at that. This kit also uses and ships with the very latest Bosch 4.9 oxygen sensors, which have become the industry standard replacing the older 4.2 models. It has a linear 0-5v wideband analog out to connect to the 52mm dual air fuel ratio gauge supplied with this kit and can also be run simultaneously into aftermarket ECU’s, it also has a simulated narrowband output that can be run back to the factory ECU if you are replacing the factory narrowband sensor with the Spartan 2 wideband so that your car’s ECU will still receive the info it needs to function properly.

The Spartan 2 wideband controller itself has been made with all automotive grade components, the same quality that you would find used by major car manufactures in what they would consider critical systems in their vehicles. These levels of components mean increased reliability, an increase in resistance to electromagnetic interference and overall a higher level of durability than non-automotive grade components.

List of features for the 52mm LED Spartan 2 dual wideband gauge kit

 

Bosch 4.9 02 Wideband Sensor IncludedBosch 4.9 02 Wideband Sensor

This dual wideband gauge kit comes with a latest generation genuine Bosch 4.9 02 sensors, we specifically import these sensors from the USA to here in Australia just for these kits and you can be assured they are genuine Bosch wideband oxygen sensors. These 4.9 sensors superseded the older 4.2 models and they improved on their design and function in the areas of accuracy, response rate and life expectancy. When buying an air fuel ratio gauge setup, the 02 sensor itself is one of the most important aspects, we have you covered here.

 

0.01 Lambda Accuracy

14point7 takes extreme pride in the accuracy of their Spartan 2 wideband controllers, because of the high quality components used and their extensive factory calibration process each unit goes under, this little unit boasts a 0.01 Lambda accuracy out of the box. Another feature of these is that they do not require any free air calibration ever. Unlike other wideband air fuel ratio gauges on the market which get you to remove the sensor from the exhaust after certain periods to do a free air calibration, the Spartan 2 is designed so this never needs doing.

 

Wideband 0-5v Analog Output 10-20 AFRWideband Analog Output

The Spartan 2 has a linear wideband analog output, which can be used to connect to air fuel ratio gauges, ecu’s, data loggers etc. If you want to take advantage of your aftermarket ECU’s closed loop function or auto tune, you will need to run the wideband analog out from the Spartan 2 back you’re the analog in on your aftermarket ECU. There is no problem sharing this output between the air fuel ratio gauge supplied in this kit and ECU’s either. The Linear Output is: 0v @ 0.68[Lambda] - 10[AFR] to 5v @ 1.36[Lambda] 20[AFR] equivalent for gasoline.  Check before purchasing that your ECU is able to accept this format, if un-sure, give us a call and we can assist.

 

simulated narrowband outputNarrowband Output

The Spartan 2 can also output a simulated narrowband signal that you can use to remove the factory 02 sensor and replace it with the Spartan 2 and still provide the ECU with 02 data that will keep the car running as it would with the factory oxygen sensor. If you simply remove your cars old narrowband sensor and replace it without running a narrowband signal back to the ECU, it will throw an error code and your fuel economy will suffer, so if you are replacing your factory narrowband with this unit, make sure you run the simulated narrowband signal from the Spartan 2 back to your car’s ecu.

 

02 sensor temperature monitorMonitors 02 Sensor Temp

Another handy feature of the Spartan 2 wideband is that it can actually measure and report sensor temperature, some of you might not know why this can be helpful, so I will explain. It’s important when placing your oxygen sensor to not only angle the sensor correctly in your exhaust, but also to place it where the sensor is not exposed to too much or too little heat, both of these can be bad and shorten the life of your sensor. The Spartan 2 comes with a little LED light you connect to the kit which will blink slowly if the sensor is too cold, or blink fast if the sensor is too hot. It also will just remain a solid light when the sensor temp is optimal and installed into the ideal location in the exhaust. One of the leading causes of premature sensor failure is related to improper placement, with this feature you can see if the sensor is placed in the optimal position in your exhaust system for sensor longevity.

 

Output Diagnostic Sequencer

This dual wideband gauge kit has a nifty little feature that can help you make sure after install that you’re ECU and air fuel ratio gauge are seeing the correct readings and all your wiring is correct and free of any issues such as voltage drop or ground offsets. When the Spartan 2 is first powered, it will output two calibration voltages before moving to live readings. It will output 1.666 volts (13.3AFR) and 3.333 volts (16.7AFR), you can use these calibration voltages to make sure the dual air fuel ratio gauge supplied with this kit is receiving the full un-effected voltage by checking on power up of the gauge it is displaying 13.3AFR first followed by 16.7AFR shortly after.  If you have also connected the wideband output to your aftermarket ECU, you can check the ECU is also receiving the correct voltages and displaying the correct AFR’s to ensure everything is correct. This is a very handy little feature that professionals in the business using these wideband gauges have commented to us many times on, and even for end users it’s great to be able to confirm simply that the air fuel readings you are seeing on your gauge or ECU are actually correct.
