2-1/16" WIDEBAND STREET AIR/FUEL RATIO, 10:1-17:1 AFR, ULTRA-LITE

I would recommend giving our tech line a call at 866-248-6357 for assistance on this.

There actually is no difference between the two as it will only come down to cosmetic appearances.

Thank you for your question. You will want to install the O2 sensor roughly 6-8" past the collector.

Thank you for your question. Unfortunately this unit can only send a wideband signal: 0v = 10.0, 4v = 17.0

Thank you for your inquiry. We don't advise mounting this gauge in a position where it is exposed to the weather. It is designed to mount inside the car.

Thank you for your question. It cannot record and playback a pass, however, it does have a 0-4v output that you can run to a data logger or other device to record the readings with. We have some wideband gauges, such as the #4397 which has peak recall you can use to see your max "lean" reading from a run, but we do not have anything that will record entire runs.

Thank you for your question. Unfortunately, we do not offer just the gauge head by itself. If yours is having issues, you can send it in to us for service with the information on this form: https://www.autometer.com/media/Service_Form.pdf

Thank you for your question. You can always send in your AutoMeter products for service if they are having issues. We will evaluate them when we receive them and then contact you with what options we have available as far as repairing or replacing your unit as well as any associated costs. The evaluation itself is done for no charge, all you need to do is get the gauge in to us. Any repair or replacement we offer may have an additional cost, however, you can always decline all the options and we will send the unit back to you in the same condition that we received it. The older the unit is, the less likely it is that we can repair it, but we are always willing to look at it and see what we can do. You can find a form with the information for sending in a product for service here: https://www.autometer.com/media/Service_Form.pdf

Thank you for your question. Yes, this can be used if you weld in a bung in the exhaust. A lot of factors go into the lifespan and it will vary per application. The gauge has a 1-year warranty but we certainly stand behind it much longer than that. We would expect the gauge to last many years.

Thank you for your question. Yes, harness #5252 is 25ft and works with this gauge.

Thank you for your question. Due to the unique way these gauges are assembled, the placement of the LEDs and the way the circuit board is composed, there is no other form of back lighting besides those LEDs. Unfortunately, the gauge will not illuminate any more than the LEDs on the display.

Hi Robert, thank you for the question. We only sell our wideband air/fuel ratio gauges as a kit with the harness and sensor. We do service our gauges and you can send in your gauge for evaluation and service. While this form isn't required, this is the type of information you'll want to include along with an invoice or receipt if the product is within or near the 1 year warranty period: http://www.autometer.com/media/Service_Form.pdf

Thank you so much for contacting us. The E02 code typically means there is a connection issue between the gauge and the sensor. This could be damaged wiring, a pin in a connector that isn't seating properly or can also be caused by using a non AutoMeter oxygen sensor. I would recommend checking the wiring first. If you've got other questions, I strongly recommend contacting out tech team at 866.248.6357, hitting the Chat link at the top of the page or emailing us here: http://www.autometer.com/resources/index/ask_a_question Hope this helps!
