Review: Works like a charm - Works great, the silver ring makes it look OEM in my G8. Datalogging works great too with the PC port. If you buy a cable to do datalogging, MAKE SURE TO GET ONE WITH an FTDI Chipset. Review: Dual Gages Make Reading Easy in Most Conditions - I added this gage to my older Volvo Penta V8 to enable tuning the ECU for best performance. It wasn't to difficult to install considering that I didn't need the gage installed in the Dashboard. The engine is in the back of the boat and the dash board is 10ft forward of the engine compartment. I sat in a rear seat with my Laptop and adjusted the fuel delivery for 14.7 through out the RPM range. Having the digital display was good for precision and the radial LED's to emulate an analog gage was nice to get a quick reading. ## Features - FASTER Sensor Frequency for faster O2 sensor feedback - FASTER Analog Output Speed helps ensure that your ECU sees changes in air/fuel ratio as they happen - ENHANCED Heater Control for superior sensor performance in forced induction and other high performance applications - Large digital readout and programmable β€œDigital Needle” provides the functionality of a needle gauge with the pinpoint accuracy of a digital display - Digital display in AFR or Lambda - 52mm (2 1/16”) diameter gauge body with included interchangeable faceplates and bezels - Bosch LSU 4.9 wideband O2 sensor - Patented 100% digital wideband air/fuel ratio technology! - Faster sensor frequency for faster O2 sensor feedback - Faster analog output speed helps ensure that your ECU sees changes in air/fuel ratio as they happen; Included components: gauge,genuine bosch lsu4.2,3ft. cable, silver bezel,more - Faster analog output speed helps ensure that your ECU sees changes in air/fuel ratio as they happen - Enhanced heater control for superior sensor performance in forced induction and other high performance applications ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B072MXHR5Y | | Best Sellers Rank | #984,568 in Automotive ( See Top 100 in Automotive ) #658 in Automotive Gauge Sets | | Brand | Innovate Motorsports | | Brand Name | Innovate Motorsports | | Customer Reviews | 3.7 out of 5 stars 44 Reviews | | Global Trade Identification Number | 00856428039241 | | Included Components | See description | | Item Type Name | Gauges | | Item Weight | 1.6 Pounds | | Manufacturer | Innovate Motorsports | | Material | Aluminum | | Material Type | Aluminum | | Model | 39240 | | Number of Items | 1 | | Part Number | 3924 | | UPC | 856428039241 608067014390 | | Unit Count | 1.0 Count | | Warranty Description | 1 year mfg, excludes O2 sensor | ## Product Details - **Brand:** Innovate Motorsports - **Material:** 100% Innovate Motorsports - **Item Weight:** 1.6 Pounds - **UPC:** 856428039241 608067014390 - **Global Trade Identification Number:** 00856428039241 ## Images ![Innovate Motorsports 3924 39240 MTX-L Plus: Advanced Digital WIDEBAND AIR/Fuel Ratio Gauge KIT, 3 FT.
