Additional Information with Diagnostic Trouble Codes

Hi,

I'm using OBD Car Doctor on IOS (latest version on app store as at 22 January 2015) connecting to a Mazda RX8.

When I read a diagnostic trouble code (for example P2270), there is a lot of supplementary data also recorded.  This looks really useful, as I would like to try to correlate the appearance of a trouble code with engine condition at the time.

However, the supplementary data is all corrupt.  Engine RPM is shown as 29.00 when I know that when the DTC was raised I was on a motorway, cruising at about 3500RPM.  Similarly speed is shown as 1km/h, which is not possible, and Air Intake Temperature shows as 4294967296.00C!

If I read the same measurements from the real time dynamic parameters screens, I get much more plausible numbers - but that doesn't help me correlate with the trouble code instant.

Can anyone offer any help or advice please?

Thank you.

Please try to read trouble codes and then send us a debug log with appropriate option in Settings, also please provide the observed values, we will check the issue. Thanks!

Thanks for replying.  I can provide a log file.  Do you want me to email it or is there a way to upload a log file as an attachment to the forum posts?  (I can't see one).
