Bluetooth Module for Comms to Tablet?

[Androo007]

Hi Guys,

 

I’ve been toying with the idea of buying a windows tablet and running this in the space of the double DIN for a live dash. However, the connecting cables are either data or power.

I’ve read somewhere that you can actually connect a BT module to the ECU to talk to it, is that right? If so, how the heck do I do that?!

This way I would retain the usual charging hooked to ignition, then comms via the BT module.

Would this be a possible and ideal solution? I’d imaging the actual lag for comms would be pretty minimal.

Although good with spanners a plonker with electronics so would pass any steps onto my tuner…. If you could please help that would be really appreciated!

You can wire the CAN output from the ECU to a OBD port as per attached image.

Then you need a suitable dongle and App for the tablet. It will then be an option to display the following parameters.

PID Number	Description
PID01	Number of CE (Check Engine) Codes
PID03	CLL (Closed Loop Lambda) Status
PID05	ECT (Engine Coolant Temperature)
PID06	Short Term Fuel Trim - Bank 1
PID07	Long Term Fuel Trim - Bank 1
PID08	Short Term Fuel Trim - Bank 2
PID09	Long Term Fuel Trim - Bank 2
PID0A	Fuel Rail Pressure (gauge)
PID0B	MAP (Manifold Absolute Pressure)
PID0C	Engine Speed

Hi,
this is the way to do it wireless.
Or just use your PC tuning cable and purchase a USB to mini USB adaptor and run the PC cable direct to your WINDOWS based tablet with PC LINK installed.
If you go to my FACE BOOK PAGE, VIPEC_ LINK PRO TUNING page you will find some videos of the setup I did a few years ago.
So you can customise some awesome dash configs and have live warnings and the ability to PC log and tune with the tablet.
Hot spotted to your phone or other internet device then also gives the ability for remote desktop tuning , a service I have been offering for many years now.
I tried to load the video but the file was too big.
Regards
Dave.

Sorry to bring up an old thread.  Do you know if this would work with a Vipec v88 ECU?  is this something that could be completed with one of the can cables?

[Simon]

No the V series units did not have the OBD option it only arrived with the introduction of the I series units.

That sucks...  looks like an upgraded ECU is in my future.

I use virtual here to supply usb over wi-fi.  It works really well, you get native usb so you can run pc link wirelessly.  The module i use is a GL-MT300N-V2 which is about 20 quid.  I then use a 12V to usb unit to power it.  

 

HTH,

 Richard.
