    hi

    I found this under the bonnet on my Fiat Ducato today.
    It was caught between a pipe and some wiring loom and unconnected.

    I think it's a diesel tuning box. Make is CRD Tuning.DE

    Has anyone got one fitted to your motorhome and if so, what's your thoughts?
    I've got a 3 year warranty on mine, so don't want to connect it up incase it voids the warranty. image.jpg

    Your suspicions are exactly correct. It's a tuning box.
    You could find out where to plug it in and try it. If it all goes t1ts up you could disconnect it in a flash and pretend it never happened.
    There again, can I have first dibs if you don't want it.

    someone probably tried it and decided it wasn't for them.. or disconnected for the MOT emissions test.. ? just a guess.

    bin it .. or sell it.. I wouldn't risk using it..

    I'm not sure about that, won't a modern engine management system record such things?

    No Keith, it wont. All they do is alter the signals and trick the ecu to alter the fuel rail pressure, which in turn gives better performance (and sometimes more smoke). No harm in trying it. I have one on my diesel jag.

    I stand corrected, I must have been watching too much Star Trek. :)

    I hope my reply didn't come across as harsh/abrupt?

    No settings are changed in the ecu, it just carries on as normal but the signals from/to some of the sensors are changed slightly outside of the ecu if that makes sense?

    Not at all, I'm always happy to be corrected. Forty years of marriage have conditioned me to being in the wrong and I usually have to endure a poke in the ribs to go with it. :D

    I have one fitted to my Fiat ducato 2.3 diesel.....works great.
    I fitted one after a discussion with the best mechanic i know recommended it.
    More power and smoother....same mpg or slightly better one a run.

    Is that possible ? There was a lot of quality SiFi under that name.

    And it gave us the flip phone and the tablet.

    Thanks for the replies.
    Think I will leave it off girl the time being and will record what mpg I'm getting and ten decide.

    i tried one of those plug n play tuning boxes, total waste of money, no difference in mpg or power or mid range.
    just caused loads of embarassing black smoke when changing gear or accelerating from round abouts etc.
    Sent it back and got a refund. the 3.0 has plenty of poke without it, i just fancied more mpg

    Just increases the fuel pressure in the injector rail so when the injectors open it forces a small amount of extra fuel, because its under a higher pressure, into the cylinders.....most of which will get thrown out the exhaust as unburnt fuel.

    Waste of time considering the cost.

    I Had one on my Td4 freelander , it had an adjustment facility ( a dial in 10 increments and a switch to alter something or other ) when first fitted it made the car fly but started to kick out black smoke ( over fuelling I think ) so I turned it down . After a bit of fiddling with the settings it settled in and made the car more torquey from the off and a little bit quicker all round. I reckoned it was improving MPG by 2 or 3 and put that down to it having more poke when accelerating and so was able to change up to the next gear/s sooner. It was an auto box . Made the car much better to drive , wish I hadn't sold it now . Doh !

    I have a Torquing of Diesels box..
    With it on I get an average of just over 1mpg but more importantly for me I do not have to chase gears so much ( still cannot believe I bought a 5+ tonne van that has a 2.3 lump in it ! )
