Its Curtains for 125ps & 135ps TDCI MK6 Transit Tuning. ( & a few others )

Vantuner no longer tunes them, as they  are not  reliable & any tuning will add more risk to already over sensitive injection system.

One issue , on this Delphi injection system setup, is tolerance on fuel rail pressure deviation, anything over approx 60 bar from spec at full pelt (1600 bar) & you have limp mode. A standard van is kissing this limit anyway so even tuning which avoids any rail pressure increase directly will lower this margin..So they can run good apart from going into limp mode under full load intermittently.. What a load of bollocks.. The creators should be ashamed of themselves  – In ancient Greece, the word Delphi may mean “Womb”.. Clearly Fords 1st common rail offspring has a birth defect.

Problem solving in cases like this van’s relies on a tuner having access to something called a description file, an “A2L ” a ” Damos ” , These  illegally gained manufacturer’s  files identify maps  & functions & would in this case allow the rail pressure deviation tolerance data to be increased, but no such files exist ( outside of Fords Dearborn U.S.A  HQ) for  Fords of this vintage  so no go sadly.

 

If you need speed limiter removal , thats no problem. For EGR delete ( assuming your EGR valve is currently working ok)  just disconnect the vacuum pipe that operates the EGR. You wont get an engine light from doing this, same with fitting an EGR blanking plate. You’ll get a P0404 engine trouble code thats all, as this is a Euro 3 engine & EGR performance was not as crucial , unlike with  later Euro emissions regulations, where any EGR issue will light the MIL ( Malfunction Indicator Lamp on dash) .

 

110ps Transit Mk7 Euro 4 have a tendency to develop a vibration at about 1690rpm. It can affect any Euro 4 diesel Transit but its very rare on all models apart from the 110. Any repair or tuning that adds torque to that RPM point or corrects a loss in the case of a repair, can induce the vibration & its tricky to solve. Its a balance  / calibration error, an argument between 2 maps if you like. Not something that can be solved by someone like myself for various reasons. Here’s one  – you adjust the calibration ( mapping ) load it & its gone, 300 miles later its back. Why  ? Because some short term fuel trims via an adaptation process are reset ever time you reprogram the engine ECU so full torque, via a slight fuelling reduction isn’t available until the adaptation process completes.  As you can imagine that complicates any fix.  For this reason, vantuner no longer tunes or works on 110ps van’s. 

130ps MK7 Euro 4 Transits, I consider the 130 fragile & unreliable. The piston crown weakness that blights the 2.2 is most prominent on the 130 , & the usual EUro 4 issues ( injector wear, hunting, egr, turbo actuator failure)  seems to affect the 130 more  so vantuner no longer tunes them, but will carry out other repairs like recalibration, EGR delete, software updates etc. 

LDV Convoy still a good van to tune

Usually of about 2003 vintage, the Convoy are  beast of a van, often long wheel base , twin wheel high roof etc. Great candidates for a camper conversion or for one man & his beard (& dog) road-home conversions etc.

Often 1st owned by like Royal Mail  & charities.They come with the excellent  Transit Duratorq 16 valve turbo diesel engine in either 75ps or 90ps limited to 62 or 70mph.. All Transit tuning & maintenance advice applies… the limiter is also easily removed..see this page :  Transit Service Tips

Ford Transit Diff Ratio’s & Axle Swaps

“My van is screaming its nuts off on the motorway”, is a common complaint & leads many owners of rear wheel drive Transits get in touch hoping a remap will fix it but it is a common misconception that a remap can truly change this.. Whilst more torque & a quieter tuned engine can sometimes give the impression of less rpm, its just an illusion,

The true  solution is a different axle ratio, achieved by an axle or diff change.. if you have a 5.11 or a 5.13 currently, an indicated 70mph will be made using about 3500rpm..Anything over 3000rpm can be noisy..I’d recommend 1 full “point”  so something in the low 4’s like a 4.27 would suffice without acceleration suffering too much. How about a 3.73 i hear you say ? X amount of torque will be needed depending on your model & usage so get in touch to discuss tuning options..Vantuner doesn’t do axle  / diff changes )

Using the Ford Etis database

Anyone can enter their registration number or VIN here & bring up quite a detailed spec of their van..follow this link & select vehicle.. if the option to enter reg isn’t showing, go back to the home page , select preferences  & select united kingdom. the reg number entry should now work.. if your reg wont work enter your VIN.  This is a handy service for looking up what axle ratio was originally fitted , among other things.. to search for items once the spec is shown without trawling through every entry, press CTRL F , this in many browsers brings up a search widget for the current pages shown content.

Corsa D & Combo 1.3 Speed Limiter Removal

BT  Fleet , Openreach & various other UK utilities still seem to be auctioning off these from time to time & nearly all have a 68 or 70mph limiter, which drives new private owners nuts from what I can tell . No main dealer can remove them despite the girl on reception saying yes no problem I’ve checked with Gordon & that’ll be 100 quid please… Vantuners removal solution on these  is a bit long winded & expensive, compared to many other small van solutions, but is effective nonetheless & an optional  power or economy tune at little extra cost softens the blow. Model year 2008 on vans seem a little easier than earlier ones thankfully.

Interesting Result on 115ps Renault Trafic 2010 Tune.

Sometimes the dyno surprises & this Vivaro is a good example. The van’s performance in mine & the customers opinion was  transformed yet it “only” made 135ps & 311nm on a local super honest Dyno Dynamics dyno.. it ran great prior to tuning & was very well maintained so I suspect they don’t make the specified 115ps as standard.. sadly i couldn’t make the session to load the stock file for a “before “ run.. It’s an epic tune that I have worked out for these over the years nonetheless so no need to change anything…

Hi Martin …long time no speak …

just thought i would let you know my van has now reached 150,000 miles
and still running perfectly ..let no one say re-mapping shortens the life of an engine ..it has never been in the garage for engine related problems since you re-mapped it at 5000 miles ..

Many thanks ..hope your keeping well ..feel free to put this on your website ..will have to change van shortly so will be in touch ..

Regards

Nigel

170ps run on a 2.2 110T280 MK7.

Nice result on Ian Jones’s 2007 Mk7, it was a 110 originally but is now running 115 injectors & software, & is tuned as far as possible in the 6hrs we had.. Exhaust Gas Temperature stayed nicely within limits , smoke level is zero before 2700rpm & “acceptable” after that. The curves as you can see below are very smooth &  boost still stock at 1bar, there’s room for more power & less smoke for sure, roll on the next  session 🙂 as a result of this session, a 155ps (smoke free !) option is now available  if you have a MK7 110 or 115 in perfect order.

Dyno Test Transit Mk7 110ps

My 243ps Diesel Transit Mk7

My own Transit, a 2008 Ex RAC Short wheel base  / low roof  with a 5 cylinder 3.2l Duratorq engine, makes about 240ps & 580nm Torque, thats about 20% up from a  stock 200 Transit  & about 120% up from when i bought it 2 years back,  when it made just 105ps ( as a 2.4) .. , the plan , now pretty much achieved , was 50ps per cylinder with no hardware mods.

Here is the 1st run, bog standard,  from July 2015

200ps Transit Dyno

 

& the 2nd run, with tuning reloaded via the Droid, straight after…….

243ps - 580nm

A hybrid turbo is probably next, but there’s the issue of the stock boost mapping limits or MAP sensor to get around 1st.. the MAP sensor is a 2.5bar unit as used on all other lesser Mk7’s .. it maybe time to test the zener diode trick..
