  • Requires v.2 ODB

    By larryp1941
    Ordered this app plus the add-on Lexus PIDs. App says it requires V2 ODB. My scanner is an ODB2 which appears to use v1.5 protocol. Not enough details on the h/w or s/w to indicate this might be an issue. I’m out $40 and still can’t monitor my Lexus.
  • Cool app

    By kmk6272
    This app works great and has some pretty cool features. I highly recommend it!
  • Please add 60-130 timer!!!!

    By BigbabyKP
    Please add the ability to time between certain speeds. Great app!
  • Satisfaction

    By InterestinglyMe
    The Carista adaptor works fine with a 2004 Impreza WRX with the OBD Fusion app. They will allow you to view things like engine temperature, boot/vac pressure, a/f ratio (calculated?), coolant temperature, O2 voltages, intake temperature, etc. Maybe the KIWI3 is faster but, the money saved could go toward an Accessport
  • Bunch of snakes

    By mrich2019
    So the app is $10 bucks and the thing to get it to work is $30. That’s a lot! However, if you want to actually get use out of this and clear/ read codes, it’s an EXTRA $10! Why would you mislead us? Just make the app $20 or don’t charge extra to make it worth something. The interface is crappy and needs a huge makeover. Fix it, and you’ll get recommendations.
  • Great Customer Support

    By Squirrell223
    Fast customer service and very helpful, well worth the cost of the app.
  • Pretty cool

    By AlohaRicky
    I thought modern cars were uncool coming from my 22re, but this thing impressed me.
  • Good app

    By Faxanidu
    I had a knockoff and asked for a refund and they responded. I actually just ordered one from the recommended list. So I'm keeping the app.
  • It seems fine but.....

    By TomB212
    I think all the gauges and everything about the app seem good but I can’t get the gauges or anything to work when the engine is on. Is there something to enable that?
  • More options then you can imagine!

    By my nickmame is fine
    I needed transmission fluid temperature for my 2011 Camry. Easy!!
