Review on Innovate Motorsports 3894 Ratio Oxygen by Solomon Baron

, not analog cable /out) It doesn't work well with HPTuners If you're thinking about connecting this device to something like an MPVI Pro in HPTuners, be careful. I don't think I've read a forum thread where someone got this unit to work with HPTuners. I say this as someone who has tried countless hours and ways to make it work without success. Every now and then I think maybe I've found a way, but it always turns out to be wishful thinking. But again, I've used it without OBD data integration and have had pretty good success diagnosing AFR issues.
