  • Must have app if you own Peugeot/Citroen
    Great app!
    The clear errors option have saved me when I was 3000 miles away from home and the adblue pump failed. The car allowed only 1100 km drive before it locks starting the engine. I was able to reset it every single time, and come home without any problem.
    One suggestion though. Once the DPF start regenerating, the buzzer should be a bit louder, informing the driver that is regen-ing.
    I hope the app will continue working once Amazon app store closes.
  • Great app... when it works!!!
    This app would be a great app IF it actually worked. 9 times out of 10 it closes suddenly, usually a minute or two after opening, with "Amazon Appstore could not connect to the Internet." My Internet access works fine and my other apps don't have any connectivity problems. I was told that Amazon Appstore requires a very, very stable Internet connection as it must constantly connect to the Internet. I don't understand why the developer chose this platform when he could have published on the Google Play Store like everyone else. I regret paying the amount I did for it.
  • Works fine, but don't use a first price OBD reader
    Use a good ELM reader, with all protocols. Not a bad copy.
    ex : Vgate iCar Pro is ok.
  • Puedo confirmar que funciona para Peugeot 307 motor 2.0 del 2008, con ECU MM6LPB
    Funciona correctamente con Peugeot 307 motor 2.0 del 2008, con computadora del motor MM6LPB, sin embargo no funciona con el ELM327 azul chino, ni tampoco con el Konnwei kw903 que es de mejor calidad. Tuve que comprar un Vgate vLinker MC+, y allí funciono correctamente. Aunque solo es capaz de comunicarse con le Computadora del Motor, y la de la caja DP0 AL4. Aún así hace su trabajo, muestra mas datos, que cualquier app OBD2 universal, y te muestra los errores de la caja que otras apps no pueden, por que no saben comunicarse con la caja. Y borre mejor los errores que con otras apps con las que a veces persisten.
  • Amazing!
    This app is absolutely amazing, it registers everything I needed it to do from a tuners perspective.

    However I would like to add some pointers.

    I would like to be able to alter the look of the "gauges". I like how RPM and boost are made into a bar type gauge, but perhaps I would like the injection quantity to look the same or the other way round.

    Also the data points on the top of the page, I would like to be able to rearrange them how I see fit.

    As far as logging goes, I would like to be able to determine the datasets I need it to log. As a lot of the data is irrelevant for what I would like it to do.

    Maybe by disabling the ones I dont need or limiting the number of selected measuring points, we can increase the rate somehow?

    For the plotted datalog chart, maybe a smoothing function would be nice to display the curves?

    Also adding a simple button to start and end a log on the main screen would be superhandy.
  • Works fine with Peugeot 807 2007 HDI CAN
    Immediate ECU connection using my generic OBD2 BT adapter. I used it to diagnose a turbo malfunction (requested boost vs delivered boost). Using this I could test safely on the highway at 100 km/h at WOT to see turbo response. It was also useful to clear codes. I have Peugeot Planet (original dealer software) but FAP is much easier to use and more practical than PP with a laptop and huge dongle hanging off the USB port.
