Thanks for the info. Just ordered mine too.

Lorryman,

Did you remove the OBDII socket from its bracket to facilitate this fit?

I understand the routing down the back, but in its normal position the socket sits pretty flush to the front of the fuse box cover and anything plugged into it stick out by a considerable margin...

Cheers,

What i did was to plug in the scangauge/ultragauge etc and then undo the OBDII brackets fixing screw and gently push the whole ensemble back into the fuse box. It wont go all the way as the OBDII bracket won't allow this. The OBDII leads supplied by the scan tool companies is the low profile 90 degree one so by undoing the mounting screw and using this cable the fuse box cover goes back on with a slight hump visible once fitted. I know that some people push the OBDII lead out of its mounting bracket and then feed the socket around the back of the fuse box. Though you would need to pull it back into place for dealer visits/breakdowns etc so that you can plug in a diagnostic tool. Others have used an OBDII splitting cable so that the scan tool can be left connected and there is another OBDII port to allow the use of a diagnostic tool. Just remember to unplug the scan tool before using a diagnostic tool.



You can see the OBDII plug for the scangauge and the splitting OBDII lead in the below picture



The ultragauge comes with a similar 90 degree OBDII plug as the scangauge.



HTH Brian.

Also I did not use the windscreen mount supplied with the Ultragauge as it was far to long for the Pumas dash. Instead I had a few old mobile phone sucker mount brackets lying in the garage and I cut one of them down to fit the Ultragauge. Instead of making a mounting bracket I used velcro to hold the gauge onto the mount and as the Ultragauge weighs very little it has worked a treat. You don't even need to remove it from the velcro to use the three function buttons on the back as I just gently push the relevant corner on the screen front to activate the menu screens. However it can easily be removed to allow me to set up new gauges/screens etc in comfort from the drivers seat.

Interesting.

Is plugging in a scan tool and a diagnostic tool at the same time going to permanently break anything? Or will they just not play nicely together while both connected?

While I'm being a newb, does OBD misbehave if you plug in 2 scan tools at the same time? I was thinking of a full time ultragauge and part time (touring / off road navigation) laptop over split OBD ports...



Thanks in advance

Brian.

Any idea if there is a similar one which does work on TD5's? As opposed to going the whole ems / madman permanently mounted sensor route?

If you have two tools plugged in and the first tool is reading the EMS sensor information then the second tool won't be able to communicate with the EMS as the first tool is already communicating with that module. Also the OBDII socket supplies the power for the tools plugged in. You would be able to communicate with the ABS module though, not sure about the IPAC as it would be communicating with the EMS over the CANBUS. The 10AS communications are done with the ignition off as that is when that module is most active. Then there are possible conflicts of two tools trying to communicate with the same module that may lead to issues I haven't tried or wish to do so. If you do try it will you let me know of any issues?
