Autometer Carbon Fiber 52mm AFR or LAMBDA Digital Wideband Air/Fuel Ratio PRO Wideband A/F Kit

Product 4778 DESCRIPTION:
Knowing the exact air/fuel mixture running through your engine is the most important factor to extracting the highest levels of performance and durability. Not all wideband gauges are created equal. AutoMeter utilizes an advanced calibration method that automatically calibrates your gauge on every startup to assure you of the highest degree of accuracy over the entire lifespan of your sensor (no free air calibration is ever necessary). Compatible with nearly all fuel types, the AutoMeter Pro Wideband has a configurable display to pinpoint the exact range you want to keep an eye on. An advanced peak recall function and lean warning system make sure you’re safely making power, whether on the track or on the street. An automatically dimming display tailors light output for any condition. Data logging output is included for one wire or two wire systems in both lambda or AFR. Our specially designed O2 sensor and wiring harness are included for ease of installation. Quite simply, there isn’t a more accurate or easy to live with wideband gauge available on the market.

2 out of 5 stars.
Worked for about 4 months and then stopped
This is the 3rd guage in the carbon series that has stopped working on a car that does not see a lot of use. first the trans temp gauge, then the speedometer, not the AFR guage. What is going on at Autometer?! I don't know if I want to invest anymore in this product to try to fix or just get another brand. One other user says he is on his 3rd AFR guage from Autometer, they are not inexpensive, so I can't afford to guess on how to fix it.

Thank you for your question. No, our Pro model AFR gauges are only compatible with the LSU 4.2. Our Pro Plus models use the LSU 4.9.

Matt from AutoMeter · 7 years ago
Hi Shawn, thank you for connecting with us. Yes, the Pro Wideband is compatible with methanol and can also be adjusted so that the range is more applicable to the 6.4:1 stoichiometric point of methanol.
