Features & Product Details
The Prosport Wideband Digital Air Fuel Ratio Kit has been designed for you to provide good insurance for your engine. If you don’t know where your air/fuel ratios are, and if you continue to run your car hard then you risk either leaning your engine out, or even washing a cylinder.
The Prosport Wideband Air Fuel Ratio Gauge features the latest Bosch wideband O2 sensor which is a 5-wire heated LSU 4.9, and Prosport Inc. is the only one in the USA to use them. This wideband range reads from 10.0.1 to 20.0.1 AFR readings.
Featured with this wideband is a blue LCD with a digital readout in the center of the gauge, and a bar-graph style LED’s around the outside of the gauge that change from green (rich) to yellow (optimal) to red (lean) for immediate reference to the AFR.
Included in this gauge is the Bosch 4.9 5 wire heated O2 sensor, weld-in bung, wiring harness, and instructions for installation.

REVIEWS & CUSTOMER MEDIA
This review doesnt apply towards Rally Sport Direct, I still give them 5 stars. Perhaps I should have done my homework before buying, but I believe when a company (Prosport) says they have an output for datalogging, that it should datalog as the competitors do. I feel a bit mislead by Prosport. At the time of this review, their website states in big bold red letters that the gauge is capable of datalogging, a big selling point. It fails to mention that the signal is analog and not a digital signal, such as the AEM UEGO, which I have used in the past, and the AEM worked as advertised first time around. Basically, they should give a little more detail. It is capable of datalogging, just as the United States is capable of going to the moon (or Hollywood to act like we are going to the moon, either way) It takes way too much effort to get this to datalog on a WRX. Now I am finding myself doing what I think is unnecessary wiring and ordering more parts to make this work, and have to change parameters and scaling in Rom Raider just to be able to datalog Air Fuel Ratios, which was the sole purpose of this purchase. I know this gauge will datalog with EVOs by tying into a rear o2 sensor, but this review is save other WRX owners the hassle of going through all of this. If using with a WRX, just spend the extra money and get the AEM. Overall the gauge, wiring kit, sensor are of good quality for the price, and if it had the same ease of use as AEM and others, I would give it 5 stars. If you use the ATI or Autometer triple cluster that replaces the dash clock, it is very easy to wire in if you have any wiring experience by splicing from the clock harness. This gauge has a dimmer wire to tie into the the headlight switch, but the rest of the Prosport Digital series gauges are not dimmable. So that doesnt really make sense. I used a 7/8" holesaw to drill for the bung, then a dremel to grind out a little more for a tight fitment which leads to a better weld. Downpipe off the car of course. It is kind of tough to see the words "lean" and "rich" in the gauge, although I just want the number anyway. This may bother some people.
