Review on 🚗 Innovate Motorsports (3837) LM-2 (BASIC) Digital Air/Fuel Ratio Wideband Meter - Bosch LSU 4.9, Black by Erik Snyder

I have had many problems with this instrument which appear to be quality control issues. Unfortunately they didn't show up until after I'd had them for a year, but in that time I've only used them for 3-5 hours tuning a rebuilt VW engine. I was never able to get the laptop's USB connection to work properly, it worked for a few minutes and then shut down so I only had to read the display while driving and was unable to use the ACM Write down information for later reference. . The SD card slot is also only compatible with older (non-SDHC!) cards of 2GB or less, it would be nice of you to mention this in the manual rather than looking it up online after hours of trying to figure it out. Why isn't my 8GB SDHC card working? And finally it now freezes during warm up so I can't use it at all and after reading their online forums it looks like I'll need a new O2 sensor cable more than $$ to fix that to repair defective product. It's all pretty ridiculous. for something I've only used properly for a few days and paid a lot of money for. I wouldn't buy it again and wouldn't recommend it to a friend (but possibly an enemy!).
