Question Mysterious black box

Hi all,
I have just had an installer fit an alarm system to the F250.

While under the dash we discovered a small black box
labeled DB Power X Monitor.

The guy I bought the truck off never mentioned it and there is
no paperwork for it.

Checked DB Power's web site and the only XMonitor info I can
find is about a digital gauge system.
I have no gauges so I have no idea what this thing does.

Anyone able to enlighten me?

Went to the site and brought up the X monitor. Go to the download section there and have a look at the install pdf. Pics and all. Should be able to check out if its the one. Do you have a pyro in one of your manifolds ??? Or a plug where one was ???

Brian,
That's the box alright.
I will get under and see if there is any sign of the sensors.
Thanks.

Chased the Xmonitor.
There is a thermocouple screwed into the turbo outlet.
As this is not ideal I will drill the manifold and insert my
new one there for the analogue gauge I have bought.

There was a black hose with a screw jammed in the end.
It seems to have broken of the Xmonitor box.
Chased that back and it is tee'ed into a line and from
looking at pics on the web it appears to be a boost gauge line.
The tee piece looks like a cheap piece of plasitic crap that I
will replace with a decent brass fitting and then get a boost
gauge installed.

There was a green wire pluged into the box input marked "sensor".
I chased that and it goes into a large loom that heads to the back
of the truck.
I will need to finish chasing it to see where it ends up.
There is no signe of any temp sensor on the tranny or any pressure
sensor anywhere on the fuel line under the truck so I can't figure
where the wire might be attached.

Anyway I have removed the Xmonitor as there is no display unit
in the truck.
Called the previous owner and he did not even know it was there.
Most have been fitted before he bought it.

Another method with the boost gauge is to do the AIH delete mod and buy a AIH delete plug with 1/4" NPT port. A barb fitting can then we screwed into the AIH delete plug to run the boost gauge.
You can then just put a brass barb joiner back into your stock line - which I presume is the one going to the waste-gate controller.

If you're going to do the EBPV delete you can get the 'high-flow' turbo outlet to replace the EBPV outlet & thereby get rid of the PO's thermacouple hole.

On the good side, at least the PO's PO was monitoring EGT & so your turbo is probably in better knick now for their care.

The AIH delete is on the to-do list so I will go with the ported
delete plug, it's a neater option.
Likewise the EBPV is destined for the scrap heap. Intend buying the
replacement turbo pedestal and high flow outlet.
There are a few other things to be done before that lot.

Personally, the only things I would recommend doing before the AIH delete and the EBPV delete is ordering the parts!

OK, gauges 'might' have a higher priority, but the above mods are like removing (unnecessary for Australia) plumbing obstructions - i.e. to save fuel, lower temps, less mechanical stresses, improved reliability, more POWER, all for about $400.

The AIH delete takes about 15 minutes.

The high-flow turbo outlet takes a bit longer, maybe 4 to 5 hours. There is the risk though of upsetting the donut gaskets in the up-pipes and causing a leak. So when doing the high-flow turbo outlet and EBPV delete (turbo removal) it would be worthwhile also changing over to the IH bellowed up-pipes at the same time (sorry just spent another $800 of your money there)... Don't ask me how I know.

Lets just say that it took me 2 goes to get it right (yes, I tried to defer the $800 IH uppie cost into the boss's next accounting period).

Mate,
that whole job is over $900 Australian plus freight!
The missus will have a fit.
I know it's logical to do it all at once, don't want to be pulling it
down repeatedly doing each bit one at a time.
I will have to slowly accumulate each part till I have it all ready to
go in one hit.

Yeah mate, it's not a job I'm looking forward to.
Hours laying on my belly on to of an engine is not going to be fun.

Got the tapped AIH delete plug on it's way from RR.
Have installed LPO pressure, EGT, Tranny temp and
boost gauges into the cab.
As soon as the AIH plug arrives I will get the business
end of the gauges installed along with the oil bypass
filter and auxillary fuel filter.

Got all the bits to do the hutch thing BUT there is an
aftermarket 250 litre fuel tank on the truck
so getting it off to do the job ain't gonna be easy.

Thanks for the offer but I just wouldn't feel right burdening you with it.

I did the Hutch mod on my Long Ranger 270 litre tank. Getting the last of the fuel out to drop the tank was the biggest issue.
As the tank is 270ltrs I didn't bother with the Harpoon mod. I was able to just drop the front half of the tank to get at the fuel pick-up port. Then work from there. It wasn't too bad!
