How accurate is that Scan My Opel app ?
« on: 26 March 2014, 22:05:49 »

Thought I'd try it on the tablet.

I cleared these codes to see which came back.. No idea why some are red, orange, green..  :-\



These are after clearing few days later...



Along with live data (at idle)





I haven't a clue what any (well most of) that livedata means..

from the app details ...

"Fault code status meanings:
red - present
yellow - intermittent
green - not present"

Thanks for that Entwood  :)

..But if they are green shouldn't they clear themselves  :-\ .. I did clear them with the Erase option manually but some came back as Red/Orange that where green, odd  ???.

If you cleared them, then there should be no codes (assuming the thing works properly, and I'd expect this part to work, as its well known how to do it), so the fact that some have reappeared would indeed mean they are intermittent or present, as they have come back.

Simples.

As I understand it .. the ECU "records" any faults detected and has a "priority" type list built in to it ... different faults have different levels of settings (x, y, a) ... but if a fault has occurred "x" times it is a "pending" fault, if it has occurred "x" times within the last "a" cycles - be it starts/minutes/selections whatever, it is an intermittent fault, once it occurs "y" times it is now a "present" fault.

Probably totally wrong.. but that's how I understand it .. :)

Thanks for the clarification  :y

Anyone know what the live data should be like on a reasonably healthy 3.2 Omega by any chance that could look over mine above ?  :)

Unfortunately you have NOT published useful "live data" .. as the engine is not running !!

This is easily seen as the fuel pump is OFF, the RPM is zero, the Mass Air flow is zero and the 02 loop is "inactive" .... 

IMHO "live data" means .. "engine running data"  ... but that's just me ..  :)

Engine was running at idle see coolant temperature 54c, When revved the RPM, Mass meter etc. where 0..

Well the data received reckons the engine was stopped ... or your bluetooth device ( I assume an ELM327) is not talking to the phone correctly .. if it's a "cheap and cheerful"  chinese one then many of them are not too good.

I went by the RPM=0 and assumed (wrongly) that the coolant temperature was residual ... as a "normal"  running temp is around 85 degrees

No worries I see how it could be mistaken for being off, Car had only been running for 5-10min roughly, Not used it today..

Reading the advert ... instant question .. what version of Android are you using ??? 

The advert says it won't work with Android 4.0 and up ...... so check which version the tablet is using ..

4.2.2 on the Asus tablet.

Reading a few reviews they are generally good.. 

"Excellent product, worked fine straight out of the packet. Although the description notes it does not work with Android 4.0 or higher, this is not the case, at least with me. I used it successfully with my Samsung Galaxy S2 and the Torque app running on Android 4.1. Very useful device.

Definitely worth spending an extra few pennies to get this model."

Can't answer that one then .. might be worth downloading the "Torque" app .. the "lite" one is free and seeing if that gives anything different. I use "Torque Pro" and get pretty good live data, but can only do engine stuff ...

I'll re-download that app...

I did have the "Torque Pro" before i had to reset my tablet and remember the RPM did work on that, Just thought the Scan My Opel would be better for Opels/Vauxhalls
