I didn't explain my point very well and for my sins I drive a TDi Galaxy which produces it's maximum torque (330Nm) at only 1800 rpm so I get to use it regularly! The engine itself is going to be at it's peak efficiency at around it's maximum torque figure BUT aerodynamics also come into play to a greater extent as the speed increases which will cloud the issue somewhat. It's very noticeable on the Galaxy that if you devioate either side of 1800 rpm that fuel consumption suffers, I did a recent trip to Sandown Racecourse from Gainsborough, Lincs. In one direction steady 70 on the motorway, cruise set and used to accelerate back to 70 after roundabouts gave a fuel consumption of 44.9mpg On the return journey staying at a very boring 55 mph (1800 rpm) gave an incredible 54.7 mpg.

But surely even when cruising the max torque RPM means that even at reduced levels i.e. throttled back the engine is producing most power with least fuel and thus at the optimum mpg point?

It's a major task to install it afterwards, maybe better to sell what you have and buy one with it fitted already. Is it worth having? YES! Regards - John

The TomTom reciever seems to work anywhere in my Gal (I was doing tests with it compared to the installed Clarion unit). The permanently installed unit has its receiver at the left hand side of the dash under the tax disk, it's unobtrusive and hidden from onlookers. Regards - John

>>In theory you don't need a filter when in recirculation mode, as the air has already been filtered on its way into the cabin<< How do you get in without opening a door or window ? What about when you drive with the window open ? Sorry, just being argumentitive :lol:

I would be very tempted to get another opinion, even a Ford Main Dealer would be worth a shot. It sounds very unlikely to be a valve to me because they usually have an effect on tickover. I would be more inclined to ignition / injection problem which would be easier and should be cheaper to sort out. Regards - John

I assure you it is most certainly NOT an urban legend, the person concerned lives in Gainsborough and was well known to me for many years, he purchased his replacement computer equipment from my business. I have said all that I'm going to say on this subject, you guys continue to discuss the Tis and admit to owning one as much as you want, I don't think it's worth the risk personally, these forums are easily monitored as is eBay. Regards - John

Hi, No apologies needed at all, no I don't work for Ford but I do know someone who's house was raided at 02:00 in the morning, searched and all of his computer equipment (nearly

I'm not getting upset or aggresive, just a friendly word of warning that people are exposing themselves to fines up to

I would be VERY careful about discussing such subjects in a public area like this. The TIS disc is copyright and belongs to Ford Motor Company and it is not in the public domain. Regards - John

The general opinion earlier was NO you don't. I tow a large Tow-A-Van that is often loaded to the max permissible weight for my 115 TDi Auto Galaxy, so far there hasn't been any indication of overheating or other problems. That said I don't cane it either. Regards - John

Most standard chargers are fine with the battery connected, I use a 4 amp one to do just what you propose and have never had a problem on any car that I've had including the Gal. In my Gal I conveniently plug it into the power socket in the boot. If you're unhappy or unsure if you get a stabilised PSU from Maplin/Farnells/RS and set the voltage to 13.80 you won't go wrong. Me personally I would go to halfords or Machine Mart and buy a 4 amp charger. If you want to be doubly safe get a power conditioner plug from a computer shop (about

Oh Dear, I must be getting old it was my obviously failed attempt at humour (Humour=something that may occasionally make you smile). TTFN - JB

Yes it's legal for off road use :D

Is the huge gap between the bonnet and the grill normal ? Nice paint job! Regards - JB

try Fordparts I have had fantastic service from them, always the right part, next day delivery and good discount. Regards - John

I think you may be wrong here and if it were a petrol car you are definately wrong. The MOT test does NOT require a CAT to be fitted, it DOES require that certain emission levels are reached and thus the only practical way is with a CAT. I was in this situation with a Range Rover, new CAT's were over

You shouldn't get any noise or vibration from it and you should get shed loads of cold air. I would take it back to the dealers, you can prove it's working (or not) by the vent temperatures, you should easily see 6 deg C or less at the vent. The realy switching on and off IF it's for the compressor should be 30 seconds or so cycle time, not chattering like a buzzer, it's possible that you have other problems causing high or low pressure trips. Regards - John

Thats it, you've got it in one ! When I had my Range Rover it had the full blown Land Rover tow-bar and a Citroen ran up the back end of it (he was way too close most of the time). I braked, he wasn't looking and he hit my Rangie. His car was 14 months old and a right off, the Rangie ? New tow ball cover needed. If the people behing think a tow bar looks threatening they can always leave more distance, if someone runs up the backend of my Galaxy thats their problem. Caio - JB

My Towsure bar also removes the metalwork in the bumper, I assume a) the Towbar is a very suitable replacement (attached straight onto the chassis rails and thus makes the other vehicle my Galaxies rear crumple zone). The towbar also has several brackets which attach to the bumper to make it secure.

Bit of a 'Bright' lad are we? Wanting to see the 'Light' :lol:

BUT, fuel is injected right on the valve seat, when the valve is closed there isnt any air movement and thus can be little or no turbulence, when the valve is open the air is sucked in and fuel added how on earth can something plumbed into a pipe 2 to 3 feet upstream have any effect whatsoever on the process in the combustion chamber ? All this device can do is admit air into the inlet manifold, this will weaken the mixture, the lamda sensor will then inject more fuel so I fail to see on closed loop how this can have any effect on emissions, fuel consumption or performance. The only way it can help is by making your wallet lighter and hence have less weight to carry in the car :rolleyes: All of the above is confirmed with the links Nimrod supplied.

I think there are a few points to be raised here:- 1) You say you haven't improved the performance so think of the following, if what you say is true you're using less fuel at a given speed you MUST have increased the engine power by making it more efficient (same power required to maintain the speed). 2) If 1 above is true then at full throttle you MUST have MORE power than before so therefore it's a performance mod. Moving onto how it works, you say "the valve works by causing turbuilance in the inlet air flow which in turn supports greater air/fuel suspension" The fuel / air ratio is controlled in closed loop by the engine management system. No matter what you do in the inlet manifold the fuel / air ratio will be the same. If this device somehow gets more air into the engine, the management system will up the fuel metering to keep the ratio the same so how can it possibly work ? Caio - JB

And there's another advantage I forgot !!! :rolleyes:
